After being registered on a few sites  that offer online  gambling I have experienced on my mobile the increasing number of push notifications from other services of gambling  field.  My mobile is not tight to those sites where I'm gambling but bounded with Gmail.

I gamble via my laptop rather than mobile.

Does those push notifications mean that Google has linked somehow my  laptop and Gmail account?

What is the best way to protect myself from such "guardianship" (if any)?

I gamble on both my phone and laptop but I do not notice anything like push notifications. What I noticed are messages through email from the gambling sites that I registered but it is not frequent at all in a way they are not disturbing me. I do not think all the sites are sending the email message.

As for push notifications, you can disable it from the settings under app management and info. Go to the app info and click on notification, then disable it if you want it to be disabled. But that is only if you installed the gambling site app on your phone. As for email, at the down part of the email message, you will see unsubscribe. Click on it to unsubscribe and you will not receive email notification from the gambling site again.

As long as you're using same email address on both your  PC and mobile device, your activities tend to be monitored to a very large extent. There ar cases when I just access a gambling site in my chrome and then when I go back to my Facebook wall, I see lots of ads bringing other gambling site to my wall. It's a combination of what an algorithm does and the fact that most of your account are linked in some way.

As long as it's just mere push notification that doesn't affect your privacy or security, it's nothing to be bothered about but the fact is that our privacy and security while using our mobile device has been brought down to the lowest point. You won't be supprised that you can just be having a physical conversation where you're talking about a particular subject matter only to go online to see recommendations regarding what you just spoke about. Some of the permissions we grant to our device monitors and take record of the conversation we're having and bring ads and recommendation that's close to that niche on our timeline.

Disable that notification. It's always in the settings. and if possible just use a throwaway gmail account or simply just use something else like protonmail. Classifying those emails as spam isn't even necessary anymore if you are just using an email that you don't care whatever is going into it.  Casinos can modify the user's settings by the way, I have seen it myself when I unsubscribed but after a few months, I received some emails from them which is just like a notification.

From other gambling sites that you are not registered with? That was supposed to not happen unless that gambling site is also connected to the one you are registered with.
Well, the problem is how you could stop a push notification if that application is not even installed on your phone because you will need to select the application first before you can find the disable or enable button. (On or off for other devices) That's why I am a bit surprised that you will find them in your notifications. Regarding using Gmail on all accounts, the same setting is applied. They should not be notifying you about anything gambling related even if you used that account for one or two gambling sites. I checked my e-mail and yes, I didn't find anything from other gambling sites that I am not subscribed to or registered with.

If there's anything, it will be the Google Chrome on your phone. I always search for basketball scores and now it notifies me with NBA and WNBA live scores.

3^rd party cookies just stroked my mind. They may analyze my traffic and send data to interested parties which are bounded with Google. The latter may in turn share those data on mutually profitable basis (let's say via Google ads)  with   other gambling sites. Is such scheme possible?

Looks like you are logged into the same gamil account on your chrome browser both on your mobile and laptop. They both are in sync and that is why you are getting push notifications on the mobile browser. Logout from the Gmail ID that you have used on the mobile browser and it should work fine or you can manually switch off these notifications from the browser. For that you can do a small Google search and you will find tutorial on how to proceed.

This is because of the cookies that you accepted when browsing the website. Also Google see the information you are browsing online and give you ads based on that. But another main reason for you to see it on another website like Facebook are the cookies you are accepting.

Yes but you can decide to avoid the privacy invading OS like Android and iOS. Or do not use what is pertaining to them like Chrome, Google search engine, not register any email account on the device which means you will not use Play Store, Youtube App and everything rhayt has to do with Google.

It is simple as long as you link your google address to a specific gambling site after sometime you will see new emails from other providers of casino games.The reason for that is simple,we all know that Google does not care that much about privacy and especially Gmail which is part of their applications that they always update and innovate by adding new features.There is a cost to these innovations and that is privacy,no matter how hard they try to improve privacy so far they are not known for doing it well so I would not be surprised by such notifications,all fault of Google Gmail.You also have used the same Google account.

Well, if it's in your gmail or email, then you can simply change your settings in gmail and block those unwanted emails that do advertisements; they can go to your spam or trash section. The thing is, those emails may be dangerous because some of them might be phishing emails, wherein if a user clicks on them, it will suddenly retrieve your information, so be wary of what link you click on and what website you are visiting. Also, when it comes to websites, you better have an ad blocker so that you will not accidentally click on a website that suddenly pops out. It can also be a dangerous link, and it is common to happen when visiting gambling sites because that's where money is. So its better to search for ad blocker or how to block those malicious website and emails in order to protect your informations and of course your money, these days its dangerous to just clicking on different websites or links.

This is something I haven't heard of before. Just like other users have commented, the notifications I get from casino are only via email and it's because I subscribed to receiving those promotional offers and announcements. I am not too sure but you maybe experiencing these push notifications if you use the casino's mobile app or if when you accessed the site via your mobile device you kind of inadvertently accepted to allow push notifications when the option came up on your screen.

For the second part of the question, Oshosondy has already given us the perfect reply.

As long as I gamble at some casino sites with gmail bound from laptops and cell phones it does not have any push notifications except those that come to gmail with promotions that the site offers, but this can be unsubscribed if you do not want these notifications.

But for apps for example maybe push notifications will always be there, but I very rarely install gambling apps and I don't think that all casinos should be accessed from the site directly.

You just have to flag them as spam or totally block the number itself so that you won't get SMS or text message from gambling sites that you don't registered.

The same with Gmail (if you uses their services), just click on the ... dots on the left side mark as spam and unsubscribe. In that way there will be no more email to text messages coming from unknown source.

I do agree, though, I have experience the same, and even if I don't have any accounts on other gambling platforms, I was getting some text message as well.

If I used to my number to deposit to a casino as we have this apps called Gcash, I have noticed that after a couple of days, I will get a lot of messages as well and I'm thinking that the casinos that I have played might have been selling my phone number. And this really bothered me that I stop using the apps to gamble for the time being, but still though it's kinda late so I have to block those kind of text messages. But as far as crypto based casinos that I have registered, since I subscribed to them, I will from time to time received some promotional emails. Just surprised to hear though that gamblers here are claiming that they haven't experience this kind of push notifications from either Gmail or text message.

That is weird. I have also talked and logged on casinos and I have not received any push notifications to gamble or associated to gambling whatsoever. By chance your smartphone is of Chinese origin?
Because those smartphones usually come with a lot of trash and bloatware which indeed track what you do on the internet and show you those push notifications and advertisements.
It is likely Google does not have anything to do with those push notifications, that have other invasive ways to show you advertisements, like when you watch YouTube videos or when you see News on their Google News app, it is likely it is more about your phone being from China and those Chinese advertisement providers throwing those push notifications at you as part of their business model: they sell their smarthohones cheap and then they start getting profit from selling ads.

it is something you can disable, fortunately, but it requires some knowledge about messing with Android. Do you know anything about fastbooting, customized ROMs.or getting super admin privileges? That would help you to clean up your phone from thing you do not want to see.

I think there's a way to disable that notification so you won't receive it anymore. I'm not sure how to do that since I have been gambling using my laptop and phone with the same Gmail number registered, but I'm not receiving a lot of notifications from gambling platforms.

There's an algorithm in Google or Facebook that probably monitors your interests, and they'll send you anything related to that. It's their way of marketing for those who paid them to sell their services and products.

There's no need to panic you are still safe except you suspect a malicious activities from those notifications then it will raise concerns to handle. whenever you register for a gambling site or online casino as such, you get to see suggestive notifications resulting from the fact that google notice how frequent you visit such site so in other to make it somehow easier for yo to be able to navigate through easily, they allow such suggestive notifications of which they to have options for turning off notifications and as well as muting notifications if the have appeared to be disturbance to you.

Your Gmail isn't connected to others  site automatically by google because i know for every gambling site you have to make sure to register first before your  mail will be linked to any of the sites, they don't automatically link your mail to another site because you have your mail linked or registered on a particular site just like that. If it keeps inconveniencing you any further, just make sure to turn off notifications.

I have not also seen any gambling site push notifications before but this is because I have not installed any gambling site application before on my device. I prefer to just use the gambling site website instead. Have you installed any gambling site application before on your device? If you have not, that could be the reason you have not gotten such notification before. If you install an app on your device, you can get push notification from the application on your device.

The simple question I can ask you, is do you log into your email account both on your laptop and on your mobile phones, sometimes maybe?
If yes, then it is possible that google has linked both accounts on both devices, so when you log in, they recognize the device you are logging in from.

Also, it is possible that your allowed access to your email accounts from the sites your visited. Check your initial registration pages or profile info and terms and agreement you agreed to at the onset. It is even possible you already bookmarked these sites once you last visited or embedded their extension somehow and have not cleared your history and cache files and report logs so far.

Google account or email to create gambling site, it seems like there will never be notifications related to gambling from other services, so far I have never experienced similar problem, this is the first time I have heard of problem related to push notifications on cellphone or laptop just because use of email in gambling.
Moreover, email address linking cannot happen by itself without user intervention and this is really quite strange.

Personally, I always use an email that was specifically created for gambling, I use more than one gambling site and they are all registered with different email addresses, but I created this email only to register on the gambling site and not for other purposes.
Notifications will always be there, but only on one gambling site service, moreover this also gives me sense of comfort in any matter related to notifications from the gambling site services that are used.

Gambling push notifications is another issue I will want us to look into. There are so many gambling company today in the internet. But genuine and fake ones. Scammers have made it difficult for people to believe some of this gambling company online because I one or two way they have been scammed. Of course I am a victim of that. Even the genuine gambling company online today it's very hard for people to register and start gambling with the company because some of this fake gambling company that always use people information registered with them to penetrate into people's bank account. Please we should be careful with gambling push notifications online for some of this are not reliable.

When you register to gambling platform or any other platforms especially if the platform is a membership type of platform, they have an opt to subscribe when you are in the process of sign up and some sites do not have this and there is a mandatory subscription to their newsletter.

You can opt to unsubscribe if you want to or if the platform do not have that option you can request to unsubscribe All subscription based emails coming from membership platform have unsubscribe button at the of email if you find them annoying you can unsubscribe.

I unsubscribe on many emails subscription that I have no interest to use or not active anymore, don't hit spam if there are unsubscribe button to avoid the newsletter from being flagged as spam.

By any chance do you setup sms verification security on one of your casino account. I experienced the same too after using sms verification on one of my gambling account. Some casino usually share customer information. This practice is rampant in my local since I frequently received push notifications from local casino.


Have a spare mobile number dedicated for gambling. And set a security settings to blocked gambling related content by marking one sample as spam.

Are using an android device or iPhone? If you are using an iPhone, I'm not sure these notifications would be coming to your phone because if there is something iPhone take seriously, it's users data and personalization of information, the only thing I think you will see is email messages. However, if you are using android device, then there is high change Google has personalized your information and they are giving you notifications based on what you have done before.

To avoid all these uncertain risk, don't use your important emails to registered into casino, used a good email but it shouldn't be the one that contain sensitive information on your phone, there is high possibility of casinos sending you marketing emails which you may not even want to see in your inbox and you can't be frown at them because you probably accepted their terms and conditions to use your email for marketing during the registration.

If you do not want gambling push notification, disable it from the gambling app that is on your phone. Also check if there are apps on your phone that you do not install by yourself and delete them all.

If you are using a good gambling site, that should not be a problem. If the gambling site that you have its app on your phone sends you message through push notification, you can just go to the gambling website to check what the notification is about. If you do not want such notification, delete the app.

@satscraper
Let me ask you a question, did you have any gambling site app on your device where you get the push notification? Secondly is that did you suspect any app on your device is doing it? Go through your apps and delete the unwanted ones.

First the email used to register on those gambling sites are logged on in your phone same as your laptop which definitely we are entangled to receive mail notifications from both devices.

If you feel inconveniences having those notifications on your phone but preferably on your laptop, then you willi have to either logout the email from your phone or better still... take  he settings steps as @Oshosondy has guided.

Yes, it happens from other gambling sites, it doesn't have to be same or affiliated gambling sites for it to happen that way. Just as the common ads that appears on our screen about a related subject, a product or service you  might have engaged with, google will just at will be sending ads about some other similar products and services.

Just that in the cases of op having those notifications prompt on his phone instead of the  laptop he uses for gambling  is because the Gmail address must have been created using that particular phone that's why the notification messages are directed to the phone not his laptop. All he can do is to deactivate it through settings in his phone.

For email it's very easy, you will just have to unsubscribe, top tier casinos will give you that option. But if you register on a like second tier casinos, you can still do that if you uses Gmail as your provider.

That's why I practice to create a new email account for casinos that I will register and not use my main account.

For SMS, it's the same, depending on your service provider and the phone model itself, you can block those numbers, not just for casinos or anything that relates to gambling but any number that you are not familiar with.

Yes that is the right solution op observation of such push notifications does not only occur in gambling site, it's as a result of this connection or usage of same email as many has explained here, another thing is when signing up or registering some site one need mute some notification if you don't want them before it occur, but why your seeing it on mobile device instead of laptop is email which setting can handle.

Yeah, I commonly use the same account on both devices but never login into it simultaneously on mobile and laptop. Still further,I had   never been synchronous login at gambling service and gmail account. All of these set me thinking of some intricate  traces remaining   on my laptop after ended gambling activity.

P.S. Thanks to all advice I have prohibited the push notifications on my Android. However Google's capability to follow my activity bends my mind.

It's good you finally turned off the notification though I guessed not all devices notify users either to accept or reject when they signed up at first.
Don't be too surprised about this, Google gets majority of their funds yearly from Ads, they are the biggest digital marketers and they will do anything somehow right, in order to get users data for this, we can reduce our dependency on their services which seems free but not and that's Degoogle

 I guess it's actually due to your email push notifications. I gamble on my mobile devices but when I'm online since I registered using the same Gmail on my mobile and PC, I get same push notifications anytime there is one. The best thing to do is to switch off the notifications on the device you don't always want to receive such notifications. I do this most times and on some telegram casino where I play, I keep receiving instant notifications about new offers but then I just disable or mute the notifications and only visit when I want. Google push notifications Is similar but you have to set it your self on your gmail account management on which website is allowed to notify you.

We all should assume that, even if we take the measures to avoid tracking (disabling/deleting cookies, using different browsers/devices, VPN, etc.) chances are that our hobbies are still leaked to who knows what actors in the industry, so I would've thought just like you.

Sometimes they are nothing more than pure coincidences, but as time goes on and the industry moves inexorably in that direction, we'd better be suspicious.

You have full control of what you want to receive and what and where you link your Gmail account, you can always disable this in your security setting it is better to avoid or decline a push notification in your browser for opt-in, and yes you can link your laptop to your Gmail account to secure your account better go here
https://myaccount.google.com/ and see where your email is linking.

And about push notifications, you can go here for a guide on how to disable push notifications on many browsers
What are push notifications and what is the best way to manage them? (https://www.mail.com/blog/posts/push-notifications/194/)

Well, you probably may have agreed to some cookies for every notification relating to gambling to be sent to you. If that's not the case, then you might have mistakenly given off your email on another site for them to be able to send notifications to you. 

Due to how frequently I receive some irrelevant Google notifications from Chrome, I decided to just disable every push notification from Chrome and other browsers I am using. You can do so if you don't want to receive those notifications. 

Can disable them. Massive pain in the ass usually since google (or any machine in general) hide it in the deepest darkest dungeon of your phone, but you can disable them. As for push notifications, in general it's just a browser thing I'd say. And in most cases, which I assume the same as yours, you have your google account logged in to that browser so push notifications are enabled.

Afaik though they generally aren't enabled? You must've clicked a popup randomly by accident which enabled it or something. I've NEVER had any popups in my phone, gambling related or not. That, or I just already set up notifications to gtfo when I saw them once lol.

You just have to visit your browser settings and disable notifications.
This are the steps to disable push notifications from your smartphone on any browser.
Step 1.
Click on the three dots at the top right corner on your chrome browser.
https://talkimg.com/images/2024/06/06/cmTFw.jpeg

Step 2.
Click on settings.
https://talkimg.com/images/2024/06/06/cmth9.jpeg

Step 3.
Click on sites setting.
https://talkimg.com/images/2024/06/06/cmzlN.jpeg

Step 4.
Click on notifications
https://talkimg.com/images/2024/06/06/cmN6a.jpeg

Step 5.
Then turn off site notifications.
https://talkimg.com/images/2024/06/06/cmEVo.jpeg
When you click on turn off notifications, you might also want to select the sites you would like to receive notification from, but when you turn it off, you won't receive any messages from any site until you turn it back on.

This is very true. I think there is some sort of algorithm that Google might be making use of, which is not just the Gmail connection to our both devices; if not how, will they detect which site and which site the person visits more often and be given out ads on Facebook without you even suggesting it?
 
Until I started using my mobile phone to visit gambling sites, I had never seen any gambling ads on my Facebook page, but after one or two visits, I started seeing ads on one particular casino. I often use the plinko game, and the ads keep popping up.

It is likely this is the case, if you gamble on the Chrome browser while you are logged in, then Google can push notifications on your smartphone even if you have never gambled on that device, now you could turn off those notifications, however this is how people that are on the recovering stage of their addiction get to struggle to remain clean, as those notifications may serve the function of a trigger and those people may gamble again when they are reminded they have not done so for a while, which is why anyone that likes to gamble should always do so from a device and accounts that are not connected in any way to their everyday life.

Probably the websites where you signed up with your Gmail account have sold or leaked users' data to shady people on the internet, so they keep sending emails of the same kind to you in an attempt to grab you as a customer for services they promote, or in other cases they might be trying to hack you by sending phishing emails that if you click, you are going to infect your device with malicious data which will compromise your safety and privacy.

The best way to protect yourself is to use alternative emails when signing up at websites on the internet. Don't use your personal email in these cases. Keep your personal email only for trustworthy essential websites, services, friends, family, job and real life contacts. Avoid all the rest.

I know what I'm talking about, because I used to commit this mistake since a long ago in this crypto environment, so I still receive a lot of garbage emails in a daily basis, including those ones stating they have very intimate and shameful records of mine and that if I don't give the sender some Bitcoins, I'm going to be exposed. :D

There’s a way to stop that push notifications by simply not allowing it, and on every apps they have notifications not just in gambling. Having this kind of feature might trigger you to gamble more so better to turn it off and just allow notifications for the most important apps like social media platform and banks transactions. If you are into gambling, this might also help you to get updates from your bet online but then again be more responsible.

I gamble majorly with my mobile phone but do my analysis with my laptop. I do not receive these notifications. The only time I see some adds is when I use my facebook account, they will begin to drop adds relating to my browser history to my facebook wall. I don't know if this is what you are referring to as notification because I don't really know how they will send you notification for a product you have not subscribed to or browsed their platform. It could also be that you might have visited some websites and put in your information for access to gambling information. This way, they might be sending you those notification so that when you signup in any of the platforms, they will get their commission.

This really happened most times that you register on a site where frequently visiting so many sites that looks like the same all does the same thing will always appear on your phone Sometimes the search Engine you put in always appears as the same way other sites that you didn’t register to have they send you messages and sometimes they send you the offer and notification and benefits. This is because you frequently familiar sites that looks like them where you are betting on so it is necessary that you get other notification.

You have to turn them off on your app/browser settings and specific on notifications, or go through with each of those apps that are annoyingly goes through your notifs.

That is why I don't really allow and disables them because if you don't, you share a cookie with them every time you visit them and they'll send you bunch of these annoying notifications.

And as for google, they play a big role in here. They save our activities through their browser if you use chrome and IIRC, there's a way through its settings to disable any kind of notification.

I don’t know if a push notification but I do know that, there are still possibilities that your email could have been synchronized with your laptop or any of your devices which might trigger ads from similar platforms rendering same or similar services and I think these type of ads can be turned off(can’t remember).
I don’t think, that just by registering a particular email, a casino would have access to the details of the gambler except in cases where access is been demanded and you accept access to the details, only will it be possible by then.


I think these suggestion is directly for devices and yes I agree with you that, these kind of notifications can trigger addiction as there are always temptations of wanting to try something new especially for gamblers who love bonus hunting, as the bonuses for a casino first timers are always very tempting and most likely for a gambler to fall for them. And I think it should be turned off totally from a device and allow for only important apps and messages m.

The first thing, and I think it's the most important:
Have an email account exclusively for cryptocurrencies. If you use Gmail, for example, you can create address variations on the same account.
For example:
- Your email is: gambling@gmail.com
- On the Duelbits website you use: gambling+duelbits@gmail.com
- On another website you use: gambling+abcdefg@gmail.com

All emails will always be directed to gambling@gmail.com, and with this you can create filters and even find out which website "leaked" your email to other services.

Or, if you don't want to create another email account, you can use something more automated using your main email. For this you can use some redirectors like Firefox Relay (https://relay.firefox.com) to protect your identity.

Second: Use a different browser just for gambling, or create a new Google Chrome "profile", for example, just for that. Because we can accidentally accept browser notifications without necessarily providing an email address.

Of course, I don't see what the OP's problem is. I have them all turned off, and if I forget a new one, for example, because I have installed a new app, I remove it as soon as the first notification is sent.


Good point.

The notification that came into your email is just announcement or information from the online casino. That doesn't mean Google linked to your devices and will check or identify the email. You are responsible with your email account and not Google.

It is no problem if you used email from Google to register on many online casino. But in this matters, I suggest you use secondary email that only use for register on online casino. That is for prevention from something that we don't wants.

You can follows some member suggestion to disable the notification so you will not receive any notification even from other emails that  is not related with gambling. That is why I also suggest to use secondary email that you will use for registering an account in online casino. That will helps you from the notification that will comes to you.

I also experienced this, after I visited a gambling site, the notifications kept appearing on my laptop, what worries me is that the laptop I used was the company issued device instead of my personal laptop, How will the push notif disappear?
Same as your experience, the site I registered is also connected to gmail, so there are a lot of ads and notifs that appear, I tried to unlink my email account but I still receive spam notifs which I found disturbing, it fills up the storage, hassle to delete of files every single time, so it would be better if receiving notifications will forced stop.

You may not be using your mobile phone for gambling but I believe in each smartphone, there is always Gmail installed. So whatever emails you received in your laptop, you will also get it in your mobile phone as long as you didn't turned off the sync function in the account settings, inside the settings of your mobile phone. Also if you did not turned off the notification of Gmail app.

You can also go to mails and simply add to spam those unwanted emails that you don't want to receive anymore in the future. Some gambling sites are only too cruel to sell our data's, and this is why we might still get a message from another company later on. This is so annoying when it happens.

I think this is a topic from the "marketing" board or "help me in my online life," yeah, that is, why topic has to do with Gambling, anyway, just don't use : "....@gmail.com" there are so services where you can stay away from spam, that using gmail to register at a casino is not a good habit.

This is how Google makes billions everyday even though they offer their services for free.

Google knows that you registered to online casino via gmail while receiving email from the registered website that will be sent to Google database and they will sell these info to ad promoters then they send you related ads from the details they bought from Google and this is how the business model of Gmail, Facebook and every tech company works.

You can't run away from this completely but you can restrict from most of these by opting our gmail as the first step, use other email services like proton.

Even if you are not using Gmail still you need Gmail if you're using Android and by that, they track almost everything from your locations, app login and etc.

I do not like to tell people to use any Google products or services but I do not agree with you on this. I have registered on many gambling sites like Stake, Livecasino, Blackjack, Bcgame and other gambling sites, I do not notice any issue at all regarding spamming notifications. The problem sometimes is not the email but what the person subscribed to that he may not know they are even subscriptions of email messages like news letters.

Yeah right, I think the connection that you can attach this topic to gambling is the info that casino typically share their userbase to other casino especially their partner.

I doubt that the email provider will leak the info since it’s suspicious that the spam email is from casino. I experienced this shit when I register to local online casino, I never though that they will share my phone number to other scammy casino since they are trusted brand in the PH while I use the phone number on this specific casino alone.

Probably you've registered your mobile number to a gambling site which is tied with other platforms and  that's something no longer surprising. Most of the gambling providers are not only having a single gambling site and that is to attract more players. As far as I know you can turn it off with the gambling sites or simply block every notification that bothers you. On my end, as long as it is not stealing amounts on my account, I'd be fine with it however I do understand that sometimes it is irritating.
Another option is to avoid using personal email on gambling sites to also protect your informations against phising and malwares. It is basically a common knowledge that we should all be practicing not only in this instance.

Like other posters above said, the email that you used to register your gambling account is active on your mobile and that is why you are receiving those notifications. You should log out the email from your device, and if you are using the gambling site app, go to your phones setting and look for notifications, look for the app and turn off notifications. If all that is done, you will not be disturbed by notification push.

If you're using google search engine to search the site, logged in to your google account, then enter the casino, probably they tracked you down already, unless you are logged out, and using adblocker. Regarding push notifications, it's something you accepted as it's a permission that was asked if you want to receive push notifications from the specific site.

You can just disable notifications from where that gambling ads came from. But with regards to the ads I think the algorithm has detected that traffic from your devices are mostly from gambling that is why you receive gambling related ads more often. It is like how social media works like Youtube, Facebook and any other that is when you are browsing specific niches the system will automatically detect what interest you are into and they are showing you the related ads and contents that suits your taste. It doesn't really need to be binded but I think it's the algorithm and stuff that did it.

You should disable push notifications for the browser on your mobile phone and you won't receive any notifications at all. This is the quickest and the easiest solution to get rid of those unnecessary notifications that you are getting. As said by others, you are probably using the same Gmail in both devices which is the reason why this is happening because your data and everything is synced in your Gmail and it is available across all devices having access to that Gmail.

I would also suggest that you don't use the same Gmail address for every platform you register on, whether it's a gambling platform or anything, you should always create a new gmail when you are signing up on a new platform and save its credentials somewhere so that you don't lose access to it.

Weird question. I noticed this a long time ago that all requests from my laptop or other device combined with one Email are then displayed on my phone. Yes, it's all connected. I think this is obvious. By the way, you can look at it from the other side. This may be for your convenience. That is, if you are interested in something and you made a request for it, then over time they may recommend you something that will really help you.
I think that no one needs you and your confidential data specifically. I think that people are just trying to make money from you by analyzing your queries on the Internet. If your phone and laptop are connected by one account, then it is identified as one profile.

It's wise not to put full attention on those push notifications so that you won't gamble anytime you sees them on your phone screen or pc monitor. It's would be okay and more matured to turn the notifications off so that anytime you have spare money you can only visit the gamble site or app and test your luck.

Gambling push notifications sometimes is annoying if you click some ads and lead to a suspicious website cant lead to you annoying push of ads or even phishing links and other scam sh*t. Tho there is option to turned off all the notification if you are using chrome there is button in up above left side and there is choice to turned off the notification.

If you are using mobile or email you can turned off via casino website and usually in setting or just unsubscribe via email

I think the email of your email is the same both on your PC as well as mobile phone. As you are using the same email and you have saved your password and login ID on your email you are getting the notification. Don't worry about it. You have not been hacked and nothing bad happened to you.

A lot of these is based on cookies and your search history. You can limit the number of push messages on PC by using incognito modes, VPN and keeping your search history clean.
Yes, not only google but also other companies will try to link you with your interests, searches and stuff. They gather data all the time to give you targeted ads. Just start looking online for something uncommon, like clothes for tall women and you'll start getting ads for these all the time.
