That’s great and everybody should do that, but it’s beside the point that an app running code on your device is there. It’s even better to do all of the above and still not use the bullshit apps when there is a website available.

I use GrapheneOS and I still don’t install anybody’s app. Discounts on hamburgers with an app? Fuck that. No app for you.

Actually yeah I do install some apps, but most are open source from F-Droid.
