Privacy Policy — Dozenal Calc

Last updated: 2 May 2026

Who is behind the app?

Dozenal Calc is developed and published by Eric Naville, Bern, Switzerland. For questions about this policy or the app, you can reach me at: dozenal@weltanschauung.app.

What data is collected?

None. The app does not collect, store, or transmit any personal data whatsoever. It runs entirely locally on your device and does not communicate with any servers.

What permissions does the app request?

Dozenal Calc requests no Android permissions — no access to camera, microphone, location, contacts, storage, or the internet. The app runs offline and always will.

Is data shared with third parties?

No. Since nothing is collected, there is nothing to share.

Tracking, analytics, advertising

The app contains no advertising, no tracking SDKs, and no analytics packages. Your behaviour is not observed in any way.

Age suitability

The app is suitable for all age groups.

Open-source components used

The app is built with the Flutter framework (Google) and uses the open-source package flutter_markdown_plus to render this page and the license page. All included components likewise operate locally and transmit no data.

Changes to this policy

Should future versions of the app introduce features that require data collection, this policy will be updated in advance, and the app will clearly indicate that a change has taken place. The date at the top of this page always shows the current version.
