Applies to Frontier Measure, Android package com.jdfrontiers.frontiermeasure.

Frontier Measure processes your entered measurements, calculations, history, favorites and settings on your device. It has no app account, advertising, analytics, remote configuration, app-operated backend or automatic crash upload. The app does not request Internet access or runtime permissions.

History remains until you delete it, clear app storage or uninstall. Deleting one entry or clearing history affects the app's local database. The app requests exclusion of its private data from Android automatic backup and device transfer; manufacturer or administrator behavior may vary.

Copying, sharing and exporting happen only when you choose them. JSON backup files contain plaintext calculation data. Android's file picker may offer local storage or a provider operated by another company. You choose the destination; that provider's handling and network access are governed by its policies. Exported files are separate and remain until you delete them from their chosen location. Import validates the complete file before adding records; it does not replace existing calculations.

Google Play handles the app purchase and installation under Google's policies. Frontier Measure does not receive payment-card details or require a license refresh to work offline after installation.

For questions about the app or this information, contact jdfrontiers@gmail.com. A support message contains only what you choose to send.

If the app's data handling changes, we will update this policy.

The website itself has separate hosting and optional analytics practices described at /privacy-policy; these do not add analytics to Frontier Measure.
