MeasureMate
MeasureMate is an offline unit converter with a live dial gauge, pinned unit pairs and a running conversion history. This page explains what the app does and does not do with your data.
MeasureMate does not collect, transmit, or share any personal information. It has no network access, no analytics and no advertising.
Information we collect
None. MeasureMate has no account system, no sign-in and no server, so there is nothing for us to receive. If you set a display name or avatar, it is written to your device's local storage and never leaves it.
Data stored on your device
To make the app work, MeasureMate stores the following only on your device, using the operating system's local storage:
- Your conversion history and the unit pairs you have pinned as favourites
- The display name and avatar you choose, if you set one
- Formatting preferences — decimal places, digit grouping, scientific notation and your last-used category
- Usage counters shown on the stats screens: total conversions, per-category tallies, daily activity, streak length and the date you first opened the app
- Which in-app achievements you have unlocked
- Whether you have already seen the introductory screens
This data never leaves your device. It is not uploaded to MeasureMate or to any third party. Uninstalling the app or clearing its storage deletes all of it permanently.
Permissions
None. The Android manifest declares no runtime permissions and the iOS build requests no permission usage descriptions. MeasureMate never asks for camera, location, microphone, contacts, photo library or external storage access. When you tap Share, the app hands plain text to your operating system's standard share sheet; you choose the destination, and the app has no access to the apps, contacts or accounts you pick.
Network use
None. MeasureMate is fully offline — that is the point of the app. It contains no HTTP client, no WebView, no sockets and no cloud SDK; every conversion factor ships inside the installed app. It behaves identically in airplane mode, and nothing is ever transmitted off your device.
Third-party services
None that collect data. MeasureMate integrates no analytics, advertising, attribution or crash-reporting SDK. Its dependencies are local-only libraries: hive and hive_flutter (on-device storage), provider (state management), fl_chart (the stats charts), share_plus (the operating system share sheet), package_info_plus (which reads the version string from the installed app bundle, not from any server) and gap (layout). None of them transmit data.
Children's privacy
MeasureMate is suitable for all ages. It collects no personal information from anyone, so it does not knowingly collect data from children under 13 (COPPA) or under 16 (GDPR-K). No account, age gate or parental consent flow is required to use it.
Your rights
Everything stays on your device, so you remain in full control at all times. Clearing the app's data erases your history, favourites and stats permanently — on Android via Settings → Apps → MeasureMate → Storage → Clear data, and on iOS by deleting the app. Uninstalling removes the local store entirely. Because there is no server-side copy, there is nothing for us to access, export, correct or delete on your behalf.
Changes to this policy
If this policy ever changes, the date at the top of this page will be revised. Material changes will be noted in the app's release notes.
