In simple English
This is a place to write notes and store files safely. Every word is locked with a key only you hold. Nobody else, not even the people who made the program, can read your writing. You can use it for free on your computer or phone. You can also run your own private server if you do not want to trust anyone else.
What it is
An open-source note-taking suite with encrypted sync across devices and support for self-hosted servers. It is written in TypeScript and released under the AGPL-3.0 licence.
What it is good for
Solo builders who want a secure place for private notes, passwords, and project drafts that syncs everywhere without leaking data.
- Your notes are scrambled on your device before they ever touch a server.
- Works across desktop and mobile devices with reliable sync.
- You can run your own sync server to keep complete control of your data.
- Advanced features and custom editors often require a paid subscription.
- Self-hosting the sync server takes extra technical effort.
- The AGPL-3.0 licence places restrictions if you embed this code into other commercial software.
