Burner Email: addresses that expire in 24 hours

Need an address for a sign-up, a code, a download? Make one inside Kryptis. It receives mail for 24 hours and then it is gone. Save a message to keep it, encrypted, in the vault.

What it does

Burner Email creates receive-only addresses that live for 24 hours. You can have up to five at a time. Verification codes are picked out and shown for a tap-to-copy. Remote images in a message stay hidden until you choose to load them, so a sender cannot tell when you opened it.

Saving a message

Open a message and choose Save to Kryptis. The copy goes into Saved Emails, encrypted in the vault, and survives the address expiring. Saved Emails are included in a manual encrypted backup.

What it is not

It is receive only. You cannot send or reply. The addresses are for the sign-ups, trials and downloads you do not want attached to your real inbox, not for conversations.

Privacy

The app talks to the inbox service with a random device token that is created on the phone and stored in the Keychain. It is not tied to an account, a purchase or any other identifier, and it is deleted by Self-Destruct Mode. Burner Email is a Premium feature.

Frequently asked questions

Can I send email from a burner address?

No. Burner Email is for receiving. It is not a full email account.

What happens to mail after 24 hours?

The address stops receiving and its messages are gone unless you saved them to Kryptis.
