Well, I am asking to everyone who had an experience with it. But thanks for your insights. I use android. I don't use many apps but for example, if I use google and youtube without using my account with a GrapheneOS, then I guess, the searches I make are completely private. It would be interesting to know if they allow apps to mine some sats or is that a bad idea because it can harm the phone? Sorry if I make very ordinary questions, I am still learning about these things.

What you search on YouTube is known to YouTube because you are doing it on YouTube. The platform wouldn't make a difference. Their ability to infer an identity to the searches is dependent on other information you give it, like your account, IP address etc.
There could be mining apps, but I don't think they'd be a good platform to do it on. Get a cheap mining hardware.
Thanks for your info. I appreciate it a lot. This weekend I am going to do research on this topic. Have a nice day!
