FlexiCalc ("we", "our", or "the app") is a smart unit converter and calculator for Android. Calculations and conversions run entirely on your device; the only network uses are ad requests and currency exchange-rate updates, as described in sections 5 and 6 below. This privacy policy explains what data is (and is not) collected when you use the FlexiCalc mobile application, and how that data is handled.
Your calculation history and preferences are stored locally on your device only. We do not sync, upload, or share this data with any server. Data is persisted using the device's native storage (Capacitor Preferences, with a local-storage fallback) and remains entirely under your control:
We do not collect, store, or process any of the following:
The app requests only the INTERNET permission, which is used exclusively for the two network purposes described in this policy: ad requests (section 5) and currency exchange-rate updates (section 6). FlexiCalc does not request notification, location, camera, microphone, contacts, or storage permissions. Your calculations and conversions themselves never leave your device.
The app uses Google AdMob to display banner and interstitial ads. All app features — including history export — are free and never gated behind ads. AdMob may collect anonymous information about your device and ad interactions in accordance with Google's privacy policy, including:
On first launch, Google's User Messaging Platform may present a consent form (EEA, UK and other regions where required). If you decline personalized ads, ad requests are made in non-personalized mode. You can also opt out of personalized advertising in your device settings. See Google's privacy policy: policies.google.com/privacy.
The app relies on the following third-party libraries and platforms:
We do not sell, trade, or otherwise transfer any personal information to third parties. AdMob data is processed under Google's own privacy terms.
FlexiCalc may be used by users of all ages, including children. The app is designed to be safe for general audiences: it has no sign-up or login, no chat or user-generated content, no in-app purchases, and no usage analytics. Ads are never required to use the calculator.
Advertising shown to children is handled under Google's Families and child-directed policies: ad requests use Google's User Messaging Platform consent flow, and non-personalized ads mode is used wherever personalized advertising is not permitted. Parents can further limit ad personalization in the device settings (Google Settings → Ads → Opt out of Ads Personalization, or reset the Advertising ID).
Since all data is stored locally, you have full control:
Your calculation history never leaves your device. The app has no backend database. The only external communications are AdMob ad requests and Frankfurter exchange-rate updates. These network requests necessarily transmit technically-required data (e.g. the Advertising ID and IP address for ads) as detailed in sections 5 and 6; your calculations themselves never leave your device.
We may update this privacy policy from time to time. Any changes will be posted on this page with an updated "Last updated" date. Continued use of the app after changes constitutes acceptance of the revised policy.
