Effective 5 October 2026. Applies to the MUSTERLINE Android app (com.monroju.preparedness).
MUSTERLINE does not collect, transmit, sell or share any personal data. Everything you enter stays on your phone. The app has no account, no analytics, no ads and no tracking. It does not have the Android permission to use the internet.
Your family plan (household members, contacts, meeting places, go-bag and supply lists) is stored only in the app's private storage on your phone. We never receive it. Uninstalling the app deletes it.
If you choose to export your plan, the app creates a file or PDF on your phone and hands it to the Android share sheet. You decide where it goes. Plan files are locked with a family code by default. We never see these files.
If you tap "Use where I am now" when setting a meeting place, the app asks Android for your current location once and saves it into your plan on your phone. It is never sent anywhere. Location is not used in the background.
If you turn on the weekly supply expiry reminder, the app asks for permission to show notifications. The reminder is scheduled on your phone. It is off by default.
The one-time unlock is processed by Google Play. State map packs are delivered by Google Play. Google handles those transactions and downloads under the Google Privacy Policy. We receive only the standard purchase records Google Play provides to developers, not your payment details.
The app is not directed at children under 13 and collects no data from anyone.
If this policy changes, we will update this page and the effective date above.
