The app
YGOOW for Android puts the whole design in your pocket: a local identity, offline keys, per-message encryption, and a connection that can ride Tor.
Status
The app is in active development and headed for Google Play. The walkthrough below describes the current build; screenshots and a full getting-started guide land here as we approach release — follow the blog for news.
What it does
- Local identity, no account. Your keypair is generated and stored on the device, behind your biometrics. Nothing leaves without a deliberate action.
- Your key is anything. Start a conversation with a password (Argon2id), any file (SHA3), a link, or a random key shared in the invite QR.
- Per-message encryption. Each message can use a different key; unreadable lines show as a lock — no error, no hint.
- Connection you control. Reach the relay over Tor (no IP, no location), over bridges where Tor is blocked, or over clearnet — the app states what each mode reveals.
- Works asynchronously. Messages wait, encrypted, until the other side reconnects — even across a dropping Tor circuit.
Getting started
- Open the app. An identity is created locally on first launch — no sign-up.
- Add a contact in person. Show each other your contact QR; a key swapped face-to-face can’t be tampered with.
- Agree on a conversation key. A shared file, a password, or a random key carried in the invite QR.
- Talk. Anyone without the key sees only a locked block.
Connection modes
| Mode | Server sees your IP? | Use when |
|---|---|---|
| Tor | No | You want to hide where you are |
| Tor bridges | No | Tor itself is blocked on your network |
| Clearnet | Yes | Hiding your location isn’t the point |
Tor is off by default in the current build and toggled on deliberately; a connection setting will make the choice explicit and persistent.
Your keys, your responsibility
There is no account recovery and no administrative override — by design, we can’t read your messages or restore lost keys even if compelled. Back up your keys. See the FAQ and the whitepaper.
