Two open-source, end-to-end encrypted productivity PWAs by a EU non-profit foundation.
re/task - encrypted task manager
re/notes - encrypted Markdown notes
Built on a True Zero Knowledge architecture: AES-256-GCM, Argon2id, PBKDF2 600K iterations. The server stores only ciphertext - it physically cannot read your tasks, notes, due dates, or even tag relations.

re/notes - Encription X-Ray mode
In re/notes, click the E2E badge in the header of an open note — this launches X-Ray mode, which shows your data side by side: on the left what you see (decrypted content), on the right what the server sees (encrypted noise in iv:ciphertext format).

Export / Import
In re/notes you can export:
- Markdown (.md) — individual notes or all at once,
- JSON — full backup preserving encryption.
You can also import Markdown files, entire folders, and even Obsidian structures.
In re/task, data export and import is available in JSON format.

Self-hosting. One of the core benefits of open-source software is the ability to run it yourself: https://reapps.eu/blog/self-hosting-with-docker-compose/
Why self-host?
For most users, our public instance (https://reapps.eu) is the easiest way to get started -it’s free, always up to date, and supported by the community. Self-hosting is an option for individuals and organizations with specific requirements.
