Classi

Classi is a local-first app for teachers. All your class data stays on your device, encrypted and under your control — no cloud account required.

Your data is stored in encrypted .classi libraries kept in the app's own storage. A portable .classi-backup file can be exported automatically to a WebDAV server of your own whenever the app locks or you switch libraries, and imported again on your other devices, which keeps them in sync.

Privacy
Classi stores all data locally on your device. No analytics, no tracking, no account. The only server Classi talks to is the WebDAV server you set up yourself.
