What to expect from an ideal product
- Private.Ki stores your encryption keys only on your device, so your email and message provider never holds the keys needed to read your data.
- Unlike standard encrypted email apps, Private.Ki combines email, direct messages, and group chat under one key pair you control, not the server.
- If the provider gets hacked, subpoenaed, or compromised, attackers still get nothing readable because the decryption keys never left your phone or computer.
- Setup does not require trusting a third party with key escrow or backup, your keys stay local from the first message you send.
- Businesses switching from ProtonMail or Tutanota gain a unified encrypted workspace without splitting workflows across separate tools or exposing keys to any hosted infrastructure.
