🛡️ HOW IT WORKS
1. Open the app — a temporary inbox is generated automatically.
2. Use the address anywhere you'd enter your real email.
3. Emails arrive instantly with a push notification.
4. After 1 hour the inbox expires and a fresh one is ready — no cleanup.
Built by a small independent team. We don't sell your data — just a clean, fast disposable email app that does exactly what it says.
