FAQ

Why insist on fully offline?

Connectivity allows data to leave the device. We treat 100% offline as the baseline to eliminate uploads and tracking.

How do I back up data?

Use local export/import. Files live on your device or personal drive—never in the cloud.

Will cloud sync be added?

No. Offline100 commits to no cloud and zero tracking for a pure local-first experience.
