# WakeLink — let a trusted contact ring a loud alarm on your Android phone

> Android app plus self-hosted Go backend: someone you have mutually paired with can trigger a loud alarm on your phone even in silent or vibrate mode (no special permission), with end-to-end encrypted messages, voice and pictures, and delivery confirmation that it actually rang.

## Key behaviours

- Rings through silent and vibrate mode, and before the first unlock after a reboot.
- Tells the sender whether the alarm actually rang and when it was stopped.
- Only mutually paired contacts can connect (invite codes); either side can stop it at any time.
- Names, messages, recordings and pictures are end-to-end encrypted to the receiver's phone; the server relays ciphertext only.
- The receiver controls the volume (optional gradual rise) and which sounds and pictures are allowed.
- English and Korean.
