What SealNotes is

SealNotes is a free, open-source web notepad for storing and managing notes with end-to-end encryption. The maker says note text is encrypted in the browser with AES-256 before storage, leaving only encrypted data on the server. Notepad names are hashed before they are saved in the database. You open a note through a unique URL and password, without creating an account, and the maker says notes can be reached from any device with an internet connection. The editor provides bold, italics, and code formatting. SealNotes says it does not store or access passwords, track activity, or retain unnecessary metadata. The project is licensed under the MIT License, with instructions for running it locally if you want to self-host. It runs on the web, and support or inquiries can be sent to [email protected].
