# Share Encrypted Self-Destructing Notes > Free online secure note sharing. Create encrypted self-destructing notes that can only be read once. Close the tab and the password is gone. Live tool: https://lofttools.com/tools/security-tools/secure-note-sharing Category: Security & Privacy ## How it works 1. **Write note** — Type the sensitive information you want to share 2. **Set options** — Choose an expiration time and optionally add a password 3. **Share link** — Copy the generated link — the note self-destructs after being read ## FAQ ### Can the note be read more than once? By default, notes self-destruct after one viewing. You can optionally allow multiple views with a time expiration. ### What if the link is never opened? Unopened notes are automatically deleted after the expiration time (default 24 hours). ### Is this cryptographically secure? Yes. The tool uses the Web Crypto API for cryptographic operations, providing the same security level as native applications. ### How is this different from Privnote or OneTimeSecret? Zero-server architecture. Privnote, OneTimeSecret, and similar services store the encrypted ciphertext on their servers and hand you a link to a server-side record — meaning their database holds your encrypted payload (and any future breach or subpoena could expose it). Loft's secure-note tool encrypts client-side and packs the entire ciphertext plus the AES-256-GCM key into the URL fragment (after the # in the link). Browsers never send the fragment to any server, so the encrypted note literally cannot leave the recipient's device. Close the tab and the note is gone — there's no record on our side because there's no record at all. Self-destruct is enforced locally via a fingerprint stored on the recipient's device. ## Privacy This tool runs entirely in the browser. Files are not uploaded to a server. They never leave the user's device. ## More - All tools: https://lofttools.com/tools - Category: https://lofttools.com/tools/security-tools - LLM index: https://lofttools.com/llms.txt
