Create Secure Clip

Your text is encrypted in this browser before upload. The server stores ciphertext only. The decryption key lives in the share link fragment or can be shared separately with the short code.

Frequently Asked Questions

Is my clipboard data secure?

Yes! This clipboard uses End-to-End Encryption (E2EE) with AES-GCM. Your data is encrypted locally in your browser before transmission, and only the recipient with the exact link can decrypt it.

How long is my clipboard stored?

Your encrypted clipboard is stored temporarily. It will automatically self-destruct after a specific time limit (usually 24 hours) or after being viewed, ensuring perfect forward secrecy.

Can the server read my data?

No. The decryption key is passed in the URL hash (the part after the #), which is never sent to the server by your browser. We mathematically cannot read your clipboard.

Zero-Knowledge Encryption

The Hash Fragment Mechanism

The decryption key is generated locally and appended to the final URL as a "hash fragment" (the part after the #). Because internet browsers physically do not send URL hashes to servers during HTTP requests, the server hosting the clipboard mathematically cannot read your data. It only holds scrambled cipher text.

Burn After Read

The "Burn After Read" feature provides Perfect Forward Secrecy. The exact moment the secure link is opened by the recipient, the ciphertext is permanently deleted from the database. Even if someone finds the link in an email thread a week later, it will be dead.
