Send anything.
We can’t read it.

Zero-knowledge file transfer. Encrypted in your browser, self-destructs after reading. Drag a file, get a link — it’s encrypted before it leaves your machine, and the key never touches our servers.

You only pay when you send — no account, no subscription. Share the link as many times as you want until it expires; downloads are unlimited & free. Once it self-destructs it’s gone for good, unrecoverable by anyone — including us.

Core architecture

security

Truly end-to-end

The key is in your link, never our database. Not even we can decrypt your files — complete data sovereignty from your browser to theirs.

all_inclusive

No size limit

Send megabytes or petabytes. The only ceiling is your internet speed.

person_off

No account

Zero registration for sender or recipient. Nothing to sign up for.

timer

Burns after reading

Share the link as much as you want until it expires — downloads are unlimited. Once the timer ends (or after first open), the encrypted payload is purged and gone for good.

Built on audited cryptography (libsodium · XChaCha20-Poly1305 · Curve25519). The decryption key travels in the link fragment — it never reaches our servers, and the encrypted file auto-deletes. We can’t open your files, recover them, or hand them over.
