Where is the #prettyeasyprivacy source code actually? I really tried and always wind up in a dead end. I would expect a GitHub repo at least.
In any case, the project sounds really interesting.
Not excited about the "we only support unencrypted private keys on Android at the moment" thing, though.
Ok, finally found it. Link actually not really visible from website.
The issue tracker does not seem too encouraging, with issues as old as from 2015 marked as "new" and never responded.
