Obliv is a messenger for people who want their conversations to actually disappear. No phone number. No email. No backups. No recovery. Just a six-digit PIN you memorise, and messages that vanish from our servers the moment your device acknowledges them. End-to-end encrypted on your device before anything leaves it. The server is zero-knowledge — it cannot read, index, or recover what you send. Features • Text, photo, video, voice notes, and files • Encrypted audio and video calls with native iOS call integration • Private group chats with automatic key rotation when membership changes • Contact exchange by QR code or short ID — no directory, no lookups, no phone book • Panic wipe after repeated wrong PIN attempts. No recovery. No exceptions. • Screenshot and screen-recording protection on sensitive screens • No analytics. No crash reporting. No advertising. No third-party tracking. • PIN-only unlock. No biometrics. No device-key storage. Threat model Obliv is designed for people who expect their devices to be seized, inspected, or lost. Your identity lives on-device, encrypted with a key derived from your PIN using a slow, brute-force-resistant function. Biometrics are deliberately unsupported — no one can unlock Obliv by holding your phone up to your face. If you forget your PIN, the identity is gone. This is the point. What we store On our servers: public keys so peers can find you, transient encrypted envelopes that are deleted the moment your device acknowledges them, and opaque push tokens for wake-up notifications. Nothing else. No message content, no contact lists, no conversation history, no behavioural data. Limitations Obliv is intentionally single-device. Multi-device support widens the attack surface and is not supported. If you reset your phone or reinstall Obliv, you start over. Obliv is independent. Not affiliated with Signal, Telegram, WhatsApp, or any other messenger.
