This Privacy Policy applies to the CalculatorHex mobile app (iOS and Android), published by Ultrya Design SRL. It is separate from the Privacy Policy for the quickhex.com website.
What CalculatorHex does locally
All calculations, conversions, and values you enter into CalculatorHex are processed entirely on your device. Nothing you type into any calculator or converter is transmitted, stored on a server, or seen by us. Your conversion history (if enabled) is saved only in local storage on your device.
Data collected through third-party services
CalculatorHex uses the following third-party services, which may collect data as described below:
Google AdMob (advertising)
CalculatorHex displays ads served by Google AdMob. AdMob may collect:
- Advertising ID
- Device information (device model, OS version, language, IP address / approximate location)
- Ad interaction data (impressions, clicks)
This data is used to serve and measure ads, and is subject toGoogle's own privacy policy.

CalculatorHex uses Firebase Analytics and Firebase Crashlytics to understand app usage and diagnose crashes. This may collect:
- App usage events (screens viewed, features used)
- Device information (device model, OS version)

This data is processed by Google/Firebase and is subject toGoogle's privacy policy.
What we do NOT collect

- We do not collect or transmit any value you type, calculate, or convert in the app.
- We do not sell your data to third parties.
Your choices
- Android: On first launch, you're asked to consent to non-essential data collection. You can review or change this later via the app's "⋮" menu → Cookie Policy.
- iOS: In accordance with Apple's App Tracking Transparency framework, CalculatorHex does not track you across other companies' apps or websites for advertising purposes; AdMob on iOS serves non-personalized ads only.
