I’ve read many posts asking users to download Firefox but when a noob like me goes to google play store, it shows Firefox collects user activity, location and other data but for Brave it says that Brave doesn’t collect any data or share any data. A company like google must do a thorough investigation before putting an app of their play store. Experts who hold degree in computer science, data science etc and are privacy advocates please explain me why not to use Brave?
You can read what data Firefox collects within the play store itself. Firstly, everything is optional and thus can be turned off to make it on par with Brave. Secondly, some of the things they collect are genuinely useful, like crash logs and diagnostics.
