App: MeasureCraft: Measure Tools Package name: com.mobilecastle.measurecraft Publisher: Mobile Castle Effective date: 3 November 2026
This policy is for the free version of MeasureCraft, which offers no in-app purchases.
This Privacy Policy explains what information the MeasureCraft app (“MeasureCraft”, “the app”, “we”, “us”) does and does not handle, and how. Please read it together with the policies of the third parties named below.
By using MeasureCraft you agree to the practices described here.
The rest of this policy gives the detail behind that summary.
MeasureCraft does not collect personal data on its own servers, because Mobile Castle does not run a server that receives your data. Specifically:
Some information is stored locally on your device so the app can work and remember your settings. This data is not transmitted to Mobile Castle, and it is excluded from Android’s cloud backup. It includes:
All of it is removed when you uninstall MeasureCraft. Settings → Clear history removes your saved measurements, and Clear all local data also removes calibrations, settings and exports. See Data retention and deletion below.
Each tool reads only what it needs from your device, on your device, and only while it is open. Every permission is requested only when you open the tool that needs it, and the rest of the app keeps working if you say no.
This application runs on Google Play Services for AR (ARCore), which is provided by Google LLC and governed by the Google Privacy Policy.
AR measure uses the camera only while that tool is open. ARCore processes the camera images on your device to find surfaces and track movement; MeasureCraft keeps only the points you place and the distances and areas it works out from them, and never saves or sends a picture. In this version, AR measure opens for one session after a short rewarded ad you choose to watch (see Advertising below). If your device needs Google Play Services for AR, the app opens its Google Play page; you choose whether to install it.
According to Google, while an app uses it, Google Play Services for AR collects:
Google states that this data is encrypted in transit, is used for analytics and to improve AR experiences, and is not shared with third parties. MeasureCraft does not use ARCore’s Cloud Anchors or Geospatial API, so the location and video data those features would involve are not collected.
MeasureCraft is free and supported by ads served through Google AdMob, a Google service. Ads appear as banners on the tool list, the History and Settings screens, the Calibration Center and saved results, never on a tool while it measures, in the AR camera view, while the sound meter listens, during a calibration or on Android’s permission prompt. There are no full-screen ads when you open the app or move between screens.
The ad requests MeasureCraft sends carry no content from the app: no measurement, location, note or export is ever passed to AdMob. To select and show ads, Google AdMob (and the Google Mobile Ads SDK included in the app) may collect and process information such as:
Google uses this information to serve and measure ads and to help prevent fraud and abuse, in accordance with Google’s own policies. Where required by law (for example, for users in the European Economic Area, the UK and Switzerland), MeasureCraft uses Google’s User Messaging Platform to show a consent form before serving personalised ads, and no ad is requested until that choice is made; you can change your choice at any time in Settings → Privacy options. You may also choose to watch a short rewarded ad to unlock one CSV or PDF export, or one AR measuring session; this is optional, and the app says what the ad unlocks before it plays.
You can limit ad personalisation and reset your advertising ID in your device settings (Settings → Google → Ads on most Android phones).
This version of MeasureCraft offers no in-app purchases. It does not connect to Google Play Billing, and no part of the app can start a payment. It asks for no billing permission. Features planned for a future Premium version show “Premium features are coming soon.” If purchases are added in a later version, this policy will be updated before that version is released.

permissions (WAKE_LOCK,
RECEIVE_BOOT_COMPLETED, FOREGROUND_SERVICE)
that the Google libraries use for their own short tasks.MeasureCraft asks for no storage, contacts, accounts, phone, SMS, call log or background-location permission. Haptic feedback needs no permission.
MeasureCraft relies on the following third parties. Their handling of information is governed by their own privacy policies:
| Service | Purpose | Policy |
|---|---|---|
| Google AdMob / Google Mobile Ads | Showing ads | https://policies.google.com/privacy and https://support.google.com/admob/answer/6128543 |
| Google User Messaging Platform | Asking for ad consent where the law requires it | https://policies.google.com/privacy |
| Google Play Services for AR (ARCore) | Tracking surfaces and movement for AR measure | https://policies.google.com/privacy |
When you share an export, Android’s share sheet sends it to the app you choose (for example email or a spreadsheet app). What that app does with it is governed by its own privacy policy.
MeasureCraft is a general-audience utility and is not directed at children. We do not knowingly collect personal information from children. The app is intended for general audiences and, in line with the store listing, is not aimed at or designed to appeal to children.
Because the app shows ads, it follows Google Play’s Families and ads policies for a general-audience app. If you believe a child has used the app in a way that raises a concern, please contact us using the details below.
Data stored locally by MeasureCraft (saved measurements, notes, calibrations, preferences, exports and the diagnostic log) stays on your device and is retained until you remove it. MeasureCraft never deletes your measurements on its own: this version shows the latest five measurements and keeps the rest on your device, locked, not deleted.
You can delete this data at any time by:
Mobile Castle does not hold a copy of this data, so there is no separate server-side deletion request to make to us.
For data processed by the third parties above (for example Google’s advertising data), please use the controls those parties provide (see their policies linked above) and your device’s Ads settings.
Because MeasureCraft keeps your data on your own device and does not run a Mobile Castle server, your measurements and locations are not exposed on our infrastructure. Exports leave your device only when you share them.
No method of electronic storage or transmission is 100% secure; while we aim to protect your information, we cannot guarantee absolute security.
We may update this Privacy Policy from time to time, for example if the app adds a feature that changes how information is handled. When we do, we will update the Effective date above and post the revised policy at the URL where this policy is hosted. Significant changes may also be noted in the app or its store listing.
