Emails encrypted and decrypted on-device, never on servers. AUTHENTICATED EMAILS Verified sending guarantees you know who a message is from. Emails show the sender’s real name, verified with cryptographic proofs. UNIQUE ‘FOR YOUR EYES ONLY’ SETTING Turn on to make sure emails are only decrypted when the intended recipient is looking at the screen — as soon as they look away, the email re-encrypts. For Your Eyes Only emails are protected against screenshots/screen recordings. WORKS WITH ANY EMAIL Get started in minutes with your existing email address. No migration process or technical knowledge required. PROTECTION AGAINST HACKERS Only you can send or read encrypted emails on your account. Even if someone guesses your password, on-device authentication prevents them from impersonating you. DATA PRIVACY BY DESIGN Identity proofs work through cryptography, not by storing user IDs. Your personal data is only ever kept on your device. Combining advanced cryptography with real-world identity verification, c.Email exists because privacy, safety, and convenience shouldn’t be mutually exclusive.
