FAQ

Q: Joplin vs Obsidian? A: Joplin is fully open source with built-in sync and E2EE; Obsidian uses local files with a richer plugin ecosystem and more modern UI. Joplin fits privacy-conscious and self-hosted users; Obsidian fits those after experience and community.

Q: Where is data stored? A: In a local SQLite database. When syncing, it's encrypted and uploaded to a backend you pick (Nextcloud, S3, etc.). You always control the data.
