Write it. Lock it. Drop it.
Create a private note, share a link, and decide when it disappears.
How DropNote works
Three simple steps designed around privacy and automatic expiration.
Write
Create your note directly in your browser. Add formatted text, Markdown, or raw code blocks without tracking.
Lock
Encrypt it with AES-256-GCM using Web Crypto. Configure passwords, view limits, or burn-after-reading destruction.
Drop
Send the link. The recipient opens it and decrypts locally. The note disappears permanently when its rules dictate.
Your note is encrypted before it leaves your browser.
DropNote is designed so the server stores encrypted note content rather than plaintext. The primary decryption key remains strictly within the URL fragment and is never transmitted in HTTP headers.
Operational Transparency
DropNote does not claim “complete anonymity” or “unbreakable encryption.” While note contents are encrypted with authenticated AES-256-GCM, the service processes operational metadata required to deliver the utility (such as note creation timestamps, expiration parameters, view counters, and IP-level rate-limiting headers to prevent abuse).
