Common questions

How does AppFlowy compare to Notion?

AppFlowy offers similar workspace functionality with a focus on data privacy, self-hosting, and native performance. While Notion has a more mature feature set, AppFlowy gives you full control over your data and the ability to customize the platform.

Answer surfaced from AppFlowy

Is my data stored locally or in the cloud?

AFFiNE stores all content on your device by default; cloud sync is optional and uses end‑to‑end encryption.

Answer surfaced from AFFiNE

How is data stored and backed up?

All notes, uploads, and settings are saved in the chosen database (SQLite, PostgreSQL, or MySQL) within the mounted data directory; backing up that directory preserves everything.
