also before downloading any app, check exodus:

https://reports.exodus-privacy.eu.org/en/

Exodus Privacy is a good starting point. They also have an app to check your installed apps with.
One possible next step could be to install an Android firewall like Netguard or Rethink DNS + Firewall to block unwanted connections. Both don't require root and are well documented.

trackerControl is a good starting place ☞ https://f-droid.org/packages/net.kollnig.missioncontrol.fdroid

Unfortunaly there no easy way to get rid of it easily since many spy things integrated inside stock os ,so only open source custom os + open source apps like from fdroid .only in this combo together it make sense

You can know it doesn't if it literally can't. Likewise if it can it might. I got thinking about this the other day when, in the grocery store, I was counting cameras waiting in line. They can watch you in particular the entire time you are there. They might. Or they might not be real cameras at all. They only way you could know they aren't surveilling you is if you know without a shadow of a doubt there are no cameras at all. If they can they might. If they can't they won't.

I tend to think about my personal privacy this way. Sandbox what you can. Don't have what you don't need. But at the end of the day, your phone is a computer you always carry with you, so you can never really know for sure. Mitigate what risks you can and don't worry about it past that. Life is too short.

Use the app Brokada 5 or the paid one Brokada 6. I use the free version, tells you if an app has trackers and what they are, blocks bad ones.
