Privacy Policy

Overview

Calibra provides measurement utilities for iOS and Android. This policy explains what information is processed when you use the Calibra mobile application and how we handle it. Calibra minimizes data collection: no user accounts, advertising networks, or cloud storage for your measurements.

Information we do not collect

• No account registration or login
• No sale of personal information
• No advertising identifiers or ad tracking
• No upload of measurement readings to our servers
• No analytics SDK in the app as shipped

Information stored on your device

Preferences (such as haptics and legal acceptance) and cached subscription status may be stored locally so Pro features work briefly offline. This data stays on your device unless you delete the app.

Device permissions

Motion sensors power level, surface, angle, and compass tools. Camera access is used only for the flashlight LED—we do not capture or store photos or video. Calibra does not request GPS or location permission.

Purchases

Calibra Pro is sold through the Apple App Store or Google Play. We use RevenueCat to verify entitlement status; RevenueCat receives purchase tokens from Apple or Google, not your payment card details.

Third-party services

Apple App Store / Google Play (payments) and RevenueCat (subscription validation) process data under their own privacy policies.

Children

Calibra is not directed at children under 13. We do not knowingly collect personal information from children.
