Privacy

Your data, app by app.

@Tracker

No account and no Tracker server: your tracks, location and health data stay on your own device. Sharing with Strava or Apple Health only happens when you choose to. That is why the App Privacy section on the App Store reads: ‘Data Not Collected’.

Aurelius Structor

A local document app: you keep your diagrams as files in folders you choose yourself. The app collects no data.

Aurelius SyncGuard

Works with the folders you choose, on your own Mac. SyncGuard is not a cloud service. Full privacy information will follow at launch.

Read the privacy statement You can also find the current privacy information for each app on the App Store.
