Remove dependance on google play services
Protonmail android app is dependent on google play services and that is obviously against privacy and security.
Users who removed/disable google play services or used vanilla "lineageos" without gapps cannot get the mail client work properly.
Google play services collect every possible piece of info about the user; location, body sensors, application usage, and every other possible thing. So telling the use to enable/install google services you compromise his privacy and security by 3rd party app which is clearly against the idea if Protomail.
I hope you can correct this and have no dependence on google at all.
FDroid is really important - a key feature for a secure and trustworthy app.
fdroid is a MUST

Would it be possible for them to make a repository that users can add to Fdroid? I'm pretty sure the main Fdroid repo requires apps to be GPL licensed.
Would that translate into a Google-free life in a Jolla?
Protonmail should work without Google services installed. I use a Blackphone, that is Google free, because I don't trust Google.

With the emphasis on security, it'd be great if you could put the Android app under a free license and place it in the F-Droid repository (https://f-droid.org/) so that we don't need to use Google Apps/Services to install and run the Protonmail app.
I've noticed that the beta version asks for Google Services, but doesn't seem to need it to function. It'd be nice if you can remove this message/requirement.
