There are so many app download which ask for access personal information, it is hard to avoid now. For example the Google app is everywhere; they even have all the data what you are searching. We think we are anonymous in the internet, but the big software company can get all our information. We definitely need to carefully download app, some scammer use app to hack our PC or phone for personal data.
For example in google play store they have feature like play protect which is to protect the third party apps from stealing our personal information but not sure how much they were trusted to be.
That's another story for google play protect, it just scanned the apps that we download to protect from unknown resources and remove it. This should be a must for everyone.
So before click "allow" please read it carefully. Don't install any software from unknown source if you don't know about it.
Sometimes you can see some free greedy offer on few website or Google ad. They will ask email, mobile, address etc. So don't provide them your personal details. They can hack you by emails also. May be they will send a link to click. After click computer or phone will be on their control.
This is why I don't save my personal info, private keys or password on it or it will be a dead end and backed up will be uselss if it's already hack.
