I also got that notification from my phone's Google Calendar, and I have since deleted all of the reminders without clicking any of it in the link. This has affected all of my future appointments and alarms on the calendar but I do have some of the most vital apps installed here on my Android. I just hope that this gets forwarded immediately to Google for it to get rid off immediately. Good thing that I haven't installed my banking apps and other important things on this phone, else I might get screwed.

Come-on mate nothing like Google calendar because it reminds you of many stuff that are worth keeping, even dateofbirth among others. The important information from this thread is: never click anything that's not clear for you no matter whose platform's the ads shows. I got series of these notifications but always careful for what I click, also, Brave browser can be of a help to block those unwanted ads show from your phones or desktops and prevent you from phishing links.

I believe they send you an email that makes Google think it's an event, so they automatically add it to your calendar.

It's like buying a travelling ticket. Most companies send their email in a way Google know when and where the travel is going to happen, so it adds it to your calendar to make things easier for you.

Now that you are aware of their trick, you should start backing it up on a piece of paper or somewhere which has no connection to the internet. I'm also using this calendar, is this the red icon calendar that's already installed to each android phones?

Though I use it but I don't keep important data like my private keys, I don't store it on my phone. OP you need to act quickly though nothing happened for now but it's better to be safe and don't be confident storing your sensitive data there.

I don't use Google products, and so I had no idea Google did this. Are you saying Google automatically reads the contents of all your emails, picks out anything that looks like an appointment, ticket, event, meeting, flight, hotel, whatever, and shares that across all its apps and databases? And people just accept that this is happening? I knew Google's privacy invasion was bad, but wow. Are people honestly so lazy that they will allow Google access to literally everything about them just so they don't have to remember that they've booked a flight?

And now it seems that using Google products is also a security risk for your crypto, not just a privacy risk. For anyone interesting in moving away from all Google products, here is a good place to start: https://www.reddit.com/r/privacy/wiki/de-google

Exactly. I had a booked fly last year and Google automatically organized everything for me in many of his products. Talk about convenience, huh? But at what cost? That was what made me finally move to a privacy-oriented email provider.

They basically scrape your email and add a card on top of it with every information about the fly. So they basically have access to all of it.

They do. It's not that big of a surprise.

This is scary, though, I haven't encountered or experience it yet, upon browsing the net, there are more than 600k result about the phishing attack using google calendar.

Sometimes, we get excited when receiving invitations and haven't thought twice before clicking the link. This very tricky idea to take advantage on the others.

What a smart way to trick someone to click phishing link, and some people will actually believe that this is something legitimate, because it comes through official Google app. I never use that app, and I do not see it in my new smarthphone (Huawei), so I check on Google Play and there is available for download.

Google is actually involved in everything, and there is no doubt that it can help you in many things, but since all that is free for users, they need to in some ways to make a profit on that. They use all that data about users and make huge profits, but it is same with Facebook, Twitter or any similar service. If you use Windows OS as most people do, you are also under constant surveillance.

Privacy is a very demanding and expensive privilege today, and if you use anything to hide your track, you become even more suspicious in the eyes of those who want to control everything.

khaled0111, you probably know, but mobile phone is not good way to keep such sensitive data. I hope you can find a better solution in the future.

I decided to dig deeper into the subject and here is a great article I found:

Using the settings Google provides to tell Google products to stop collecting data on you almost certainly does nothing except stop you from seeing the data being collected on your devices or on your Google account. I fully expect they still collect and store all that data. There are lawsuits against Google for tracking users' locations even when they turn off location history, so I doubt turning off search history actually stops them from recording your search history; you just won't see it anymore. It's just like on Windows 10 when you turn all the privacy settings up to max and disable all its telemetry, yet you can see it still calls home to Microsoft owned IPs thousands of times an hour.

The only way to actual maintain your privacy from these companies is to not use them at all.
