Cloud & telemetry
What is this?
Here you connect the app to your licence and your class, see what happens with your learning data, and sync your progress across several devices. Designed to be data-minimal: you don’t need a user account, we do not record where you click, and the servers are in Germany.
These settings
- Activate licence: Enter your licence key (format XXXX-XXXX-XXXX-XXXX) to unlock all features — usable on up to 3 devices. No licence yet? You buy one in the Licence tab.
- Join a class: Enter the join code from your teacher (name optional). If you’re already in a class, you’ll see your class and school here and can leave. With school licences, your teacher manages this.
- Learning data (full version and class): We use your exercise results to support you in a targeted way — and, if you are in a class, for your teacher. Not to see where you click. There is no switch for this; without a licence the app only sends anonymous reports.
- Cloud synchronisation (full version): Backs up your progress across up to 3 devices. Auto-sync keeps everything up to date automatically; alternatively Upload (this device → cloud) or Download (cloud → device, overwrites the local state). For students, auto-sync runs automatically — at the start and end of every practice session.
Privacy
Lapicida is built for data minimisation: to learn you need neither an account nor an email address. Your exercise results serve your learning support, not the tracking of clicks. Your synced learning data sits on servers in Germany (the connection runs through Cloudflare) and is tied to your licence key, not to a personal profile.
Tip
Upload is always safe (your device backs up to the cloud). Download overwrites the local state — use it when you move to a new device and want to fetch the cloud state.
