💡 Additional information about Proton mail

🔒 Proton mail PGP encryption, anonymity

Proton Mail's security features, privacy concerns:

🌐 Proton mail precautions guide

Things to watch out for while using Proton Mail:

  • If you don't verify your recovery email, you'll block sign-up verification code emails from other platforms
  • Blocking emails from some platforms (it seems like messages are automatically blocked because of domain reputation or spam filters)
  • Because of Proton Mail's strong filtering security policies, you sometimes don't receive important emails from other email providers
  • The results of the security audit for the Proton Mail mobile app have not been released (it looks like they haven't received the security audit yet or they haven't officially released the audit report to the public)

⚖️ Precautions when using Proton Mail

Precautions that may cause your account to be suspended:

  • Duplicate sign-ups on a specific platform will result in a ban
  • Restrict the use of temporary email domains
  • Block virtual number registration (even if you create an account, it will be blocked)
  • Account banned because of username regardless of ToS

  • The Proton Mail app is not on F-Droid because it uses Google notification framework.
    Proton Mail clients rely on Google Play services and have other Analytics trackers such as Sentry
