Numa Calc — Privacy policy Updated: 5 November 2026 Developer: yair braun Contact: koshergim@gmail.com
On your device The calculator saves settings and calculation history locally. This data is used to restore your choices and continue where you left off. Android cloud backup and transfer of these app files are disabled. You can remove local data through Android app settings or uninstalling the app. You can also clear calculation history inside the app.
Advertising and permissions This advertising-enabled build contains Google Mobile Ads and User Messaging Platform. A clearly labelled optional banner is available below the calculation controls. Advertising starts only when you choose Show advertisement. The app also works without choosing this option. All users receive child-restricted treatment and general-audience (G) ads. Personalized advertising and publisher first-party ID are disabled, including for adults and users whose age is unknown. The advertising system does not use the optional Block Garden account age choice. No advertising-ID or Android Ad Services permission is requested, and no third-party mediation adapters are included. These measures do not mean that Google processes no identifiers or other data. Google may process IP address (including approximate location), device/account identifiers such as app set ID, diagnostics and ad interactions to deliver advertising, measure delivery, and prevent fraud and abuse. Google may collect and share this information as described in its SDK disclosures. Advertising requests require Internet. This app does not request location, contacts, camera or microphone permissions. When required by Google UMP, privacy choices are available through Ad privacy options. Child treatment suppresses adult consent messages; this is not verified parental consent. Google privacy information: https://policies.google.com/privacy
No cloud account This app does not have an account or a cloud-save service and works offline; its optional advertisement requires Internet. The developer does not receive calculation history or settings from this app. Children can use it without providing personal details.
Support and changes If you email us, we receive the information you include and use it to answer your request. Only include information needed to resolve the issue. Contact the developer at the email above for privacy questions. This notice will be updated if app features or data practices change.
