Eter Encrypted

Eter is a messenger built for people who take privacy seriously. Every detail is designed to minimize traces and protect your conversations against 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 intended recipient. ZERO ON-DEVICE STORAGE Unlike other messengers, Eter never writes messages to disk. Content lives only in protected memory and is wiped when you leave the app. No local files, no database, no backups. THE VAULT After 24 hours, your messages are locked in a cryptographic vault. Reopening requires mutual consent — both parties must agree. Real control over what can exist. ANTI-FORENSIC PROTECTION Screenshot blocking, aggressive RAM cleanup with native SecureBuffer, content-free notifications, and automatic wipe in risk scenarios. Designed to minimize residual traces. ENCRYPTED CALLS Voice and video calls with end-to-end encryption. Group calls via SFU supporting 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 required — just a 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.
