Eter Encrypted

Eter is a messenger designed for those who take privacy seriously. Every detail has been thought out to minimize traces and protect your conversations from extraction — even in advanced forensic scenarios.

END-TO-END ENCRYPTION
All messages are protected by the Signal Protocol with Double Ratchet. Your conversations are encrypted before leaving the device and can only be read by the recipient.

ZERO DEVICE STORAGE
Unlike other messengers, Eter does not save messages to disk. The content lives only in protected memory and is deleted when you exit the app. No local files, no database, no backups.

VAULT OF THE PAST
After 24 hours, your messages are locked in a cryptographic vault. Reopening only happens with mutual consent — both parties need to agree. Real control over what can exist.

ANTI-FORENSIC PROTECTION
Screenshot blocking, aggressive RAM cleaning with native SecureBuffer, notifications without content preview, and automatic wipe in high-risk scenarios. Designed to minimize residual traces.

ENCRYPTED CALLS
End-to-end encrypted voice and video calls. Support for group calls via SFU for up to 50 participants with adaptive quality.

PRIVATE CIRCLES
Groups with controlled access, social graph protection via HMAC tokens, and the same privacy guarantees as individual conversations.

PRIVACY BY DESIGN
No phone number or email — just username and password. No feeds, no data collection, no dark patterns. The app serves you, never the other way around.

FAMILIAR INTERFACE
Intuitive navigation you already know. Same ease of use, with the depth of security you deserve.

Eter doesn't promise the impossible. It promises to drastically reduce risk — by design.
