Can I emphasize one more time how cool Blokada is?
You don't know it but your phone is *full* of trackers. It's not better than the web. I thought that we don't have any tools to deal with it - after all, it's not a browser. But turns out there are!
Blokada works as a VPN but locally. It has a blacklist (which you can change) and it just blocks all connections to trackers or ads. It works wonderfully.
Of course Google wouldn't let it in the Play Store.
