One app for everything that wants to reach you.
NOTIFICATIONS FROM ANYTHING YOU RUN
A server, a script, a NAS, a washing machine — anything that can call a URL can buzz your phone. Five priority levels; only the urgent one crosses your quiet hours.
APPROVALS WITH YOUR FINGERPRINT
A deploy, a smart-home action or an AI agent can ask before acting — Approve or Deny from the notification shade, with a biometric check when the service demands one. Denying never needs a fingerprint; refusing should always be cheap.
SIGN IN WITHOUT GIVING YOUR EMAIL
Sites that speak Lauther see a name you invented and a random ID that exists only for them. Two sites can never work out you are the same person. Burn any identity in one tap — its alias, ID and push channel die together.
THROWAWAY EMAIL ALIASES
For sites that insist on an address: mint one that arrives as a notification, delete it when it misbehaves.
Everything that protects you is free — recovery, multi-device, biometrics, revocation. No ads, no analytics SDK, no tracking. Sign-in is an email link; there is no password anywhere. You can delete your account, and everything in it, from inside the app.
Works with curl, Home Assistant, Uptime Kuma (webhook), GitHub Actions, Apprise and anything else that can make an HTTP request.
