Private by design — proven, not promised.
Every message and file is encrypted on your device before it's sent, and stored encrypted on our servers. Keys rotate to a fresh epoch every seven days for forward secrecy, so a compromised key never unlocks the past. Our servers store only ciphertext — they never hold a key that can read your content.
Key benefits
Authenticated encryption seals every message and media file on your device before it's sent.
On phones, the keys that sign you in and seal your account key live in your phone's secure hardware (Secure Enclave / Android Keystore) where available.
Direct and group chats are encrypted end to end.
Epoch keys rotate every seven days for forward secrecy — old keys can't reopen old messages.
Servers store only ciphertext; media is encrypted on your device before it's uploaded.
