Frequently Asked Questions
How secure is this?
Your note is encrypted using AES-256-GCM, the same encryption standard used by banks and governments. The encryption happens entirely in your browser, and the encrypted content is only stored in the URL fragment, which is never sent to servers.
Is my note stored on any server?
No. Your note is encrypted in your browser and stored only in the shareable URL. We have no servers, no databases, and no way to see your content. Everything happens client-side.
What if I lose the link?
Unfortunately, there is no way to recover a lost link. The encrypted note exists only in that URL. We recommend copying and saving the link securely.
Do I need a password?
Password protection is optional but recommended for sensitive notes. Without a password, anyone with the link can view the note. With a password, they also need the password you set.
