End-to-end encrypted temporary email
A temporary inbox whose messages only you can read. Encryption happens in your browser — the server stores ciphertext it can't open.
Encrypted in your browser
Your key never leaves the client. The server only ever sees ciphertext.
Nothing to leak
We can't read your messages, so there's nothing readable to breach or hand over.
Temporary by default
Messages auto-purge every two hours; the address stays until you delete it.

Can MailFlat read my email?
No. Decryption happens client-side, so the contents are unreadable to us.
