## What is TalkOnce?

TalkOnce — the message no one else can read. Not even us.

TalkOnce is a private messenger built so that we cannot read your messages. Your messages, calls, and media are end-to-end encrypted with post-quantum cryptography — sealed on your device, opened only on your recipient's. We hold no keys.

No number. No name.
Sign up with nothing — no phone number, no email, no real name. There's no account profile to leak, subpoena, or sell.

Built for tomorrow's attacker.
TalkOnce uses hybrid classical + post-quantum encryption on every message, call, and file — so traffic recorded today can't be broken by a future quantum computer.

Ephemeral by design.
Delivered messages are erased from our servers the instant they reach you. Anything undelivered vanishes within 30 days. Disappearing-message options put conversations on a timer.

No tracking, ever.
No ad networks, no analytics SDKs, no trackers — anywhere in the app.

A full messenger.
• 1:1 and group chats
• Encrypted voice & video calls
• Stories that vanish in 24 hours
• Zero-knowledge encrypted backup, unlocked only by a code you hold
• Three privacy levels: Standard, Shielded, and Blackout (routes over Tor with cover traffic)

Radical honesty.
We tell you the exact boundary of what our servers can and can't see, in plain language, in our Privacy Policy.

Say it once. Trust no server with the rest.
