Alpha: what works, what's missing
YGOOW is not released yet. This page shows where it stands: the interface of the current build, what already works and what is still missing. There is no download here, and nothing to buy yet.
What already works
- Contacts without accounts. Scan each other's QR code in person, or add someone remotely and compare a safety number on another channel.
- One-to-one chats and group rooms, end-to-end encrypted, over Tor by default.
- Several identities behind one app-lock.
- App-lock with a password, a file, a link or a quorum, plus biometrics. A YubiKey as a second factor over NFC; over USB it is in testing.
- A decoy profile for coercion, and a panic lock.
- Dead Drop: one-time notes, in the app and at /d.
- Conditions: a key per message, disappearing messages, open-after, burn after reading.
- Delivery without Google: no Firebase, no push broker.
- A sealed backup file that restores your profile on another phone.
- A self-test that re-runs the cryptography on your own phone.
Each line in more detail, with what it does not protect against: progress.

What’s still missing
We won’t release without these:
- The Double Ratchet and the post-quantum hybrid in every conversation. Both are built and tested; live conversations don’t run them yet.
- The other security fixes within our reach, from our own reviews and measurements.
- A signed release, with the signing key kept off the build machine and its fingerprint published on the security page and in the canary.
Also still missing:
- Less for the relay to read from timing. The encrypted message header and a steady channel per device are being built and measured. What the relay can infer today is written down on the progress page.
- Delivery on real phones, measured. How messages fare on phones that save battery by sleeping is being measured right now. Until we publish the result, treat a late or missing message as possible.
- Photos and voice messages. Text only for now.
Not audited: we have committed to an independent audit when it can be paid for, and nothing on this site calls YGOOW audited.
Licensing
Still open, and settled before the first release:
- Licensing: how YGOOW is licensed and what a license covers.
- License validity: how long a license is valid.
- Updates and new features in paid licenses: what a paid license includes.
Until then there is nothing to buy and no download. When it is settled, it will be on this page.
