Unofficial ProtonMail repository
ProtonMail (https://protonmail.com) is secure email based in Switzerland. This is an unofficial ProtonMail F-Droid repository. The APKs are from ProtonApps (https://protonapps.com/protonmail-android). Note, the packages are renamed to include version nubmers. Older packages came from APKmirror (https://www.apkmirror.com/apk/protonmail/protonmail-encrypted-email) and the packages have been renamed to get under the 100 character limit in Repomaker (https://f-droid.org/en/repomaker).
