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.
