That's why I always avoid installing any apps on my phone, if I can live with a website version. Yes, websites also try to collect as much as they can, but at least there I have a browser sandbox and a possibility to use an uBlock Origin.

Of course, the issue is always with other apps that don't have a website version and require the internet to work. There, one needs to be much more careful about what he installs, and to prefer open source when possible.
