Privacy & Security: Joplin implements end-to-end encryption (E2EE) to ensure only you can access your notes. Your data is saved in an open format, guaranteeing long-term accessibility. Joplin Cloud is based in France, providing protection under strict European Union privacy laws.

Synchronization: Sync your notes across devices using various services including Joplin Cloud, Dropbox, and OneDrive. The synchronization process is protected with end-to-end encryption for maximum security.

Praised by tech reviewers as an "Editors' Choice winner" for open-source note-taking, Joplin combines powerful functionality with user-friendly design, making it an excellent alternative to proprietary note-taking solutions.
