Send a secret. It disappears the moment it's read.
Zero-knowledge, one-time links for anything you'd rather not leave sitting in an inbox or a chat log. No account, no tracking, nothing left behind.
What ends up going through Selfdestruct
A password you'd rather not type into a chat box
Wi-Fi codes, shared logins, a one-off staging password — handed over once, then gone.
Something with a name and a number attached
Bank details, ID numbers, anything you wouldn't want sitting in someone's inbox.
A handoff between people who don't share a Slack
SSH keys, API tokens, database access — passed to a contractor or client without a permanent trail.
A message meant to be read exactly once
Something personal, awkward, or just none of anyone else's business.
Built-in protection
Zero-knowledge encryption
Encryption happens on your device, before anything is sent. We store scrambled bytes we can't unscramble — there's no key on our end to lose, hand over, or be compelled to produce.
One-time, self-destructing link
The link works exactly once. The moment it's opened, the secret is deleted — permanently, not just hidden.
Duress passphrase
An optional second passphrase that reveals a stand-in message instead of the real secret — indistinguishable from the real one to anyone watching.
Quick exit
A one-click way to leave instantly and land somewhere neutral, available on every page — the small button in the header. If you ever need it, it's always right there.
No accounts, ever
Nothing to sign up for on either end. No email, no password to reuse, no profile tying a secret back to you.
EU-hosted infrastructure
Runs on servers we operate, headquartered in the EU — not just an EU region of a company based elsewhere. Real jurisdiction, not a marketing distinction.
No logs of what you send
No per-secret or per-visitor logging, no analytics scripts, nothing to subpoena that would reveal a secret's contents after the fact.
How it works
The ciphertext and the decryption key take different paths — the key never reaches the server. See the full breakdown, FAQ, and warrant canary →
