MeasureX values your privacy. This Privacy Policy explains what information is collected, how it is used, and how it is protected when you use the MeasureX application.
The app uses Firebase Crashlytics to help diagnose crashes and improve stability. Crash reports may include device model, operating system version, app version, crash logs, diagnostic information, and Firebase installation identifiers.
If you submit feedback in the app, we collect the feedback content you provide and the optional contact information you enter. This information is stored in Firebase Firestore and is used only to review feedback, respond when possible, and improve the app.
The Noise Detection feature requires microphone access to measure ambient sound levels. Audio input is processed locally on your device. The app may create a temporary local audio file during detection, and this file is deleted when detection stops. Audio is not uploaded or shared.
The Nine Grid Image feature lets you choose an image and save generated image pieces to your device gallery. Images are processed locally and are not uploaded by MeasureX.
Information is used to provide app features, process feedback, improve app stability, diagnose crashes, and respond to user support requests.
MeasureX does not sell personal information. Firebase services are provided by Google and process data according to Google's applicable privacy and security terms.
Crash and diagnostic data is retained according to Firebase service settings. Feedback data is retained only as long as reasonably needed to review and respond to feedback. You may request deletion of feedback you submitted by contacting us.
We use reasonable technical measures to protect collected information from unauthorized access, alteration, disclosure, or destruction.
MeasureX is not intended for children under the age of 13 and does not knowingly collect personal information from children.
