At a glance
CalcMate does not require an account or sign-in. According to the app's current privacy information, calculations, history, favourites, presets and settings are stored on your device and are not uploaded by CalcMate. The app displays ads through Google AdMob, offers an optional one-time Google Play purchase to remove ads, and provides optional voice commands using your phone's speech recognition service.
Data stored on your device
CalcMate stores the following information locally to support app functionality:
- Calculation history, saved results, favourites and presets.
- App settings, such as theme, language and currency.
- Premium purchase status, so the app can remain ad-free after purchase, including offline.
A backup file is created only when you choose Export, and you choose where it is saved.
Advertising (Google AdMob)
The free version displays ads served by Google AdMob. To deliver and measure ads and help prevent fraud, Google may process information such as your device's advertising ID, approximate location derived from your IP address, ad interactions and app performance information.
Learn more in Google's explanation of how it uses information from apps and sites that use its services. Where required by law, such as in the EEA and UK, consent is requested before personalised ads are shown. You can change your choice under Settings → Ad privacy choices. Ads are limited to content suitable for general audiences. You can also reset or delete your advertising ID in your device's Google settings.
Purchases (Google Play)
CalcMate Premium is an optional one-time purchase processed by Google Play. CalcMate does not see your payment card details. The app receives confirmation from Google Play that the purchase belongs to your Google account. Google Play's own privacy and purchase terms also apply.
Voice commands and microphone
Voice commands are optional. Microphone permission is requested only when you tap the microphone button. Your speech is converted to text by your phone's speech recognition service, on-device where supported, and that text is used to identify a calculator within the app.
CalcMate does not record, store or upload audio. The speech recognition service is provided by your device manufacturer or Google and is governed by that provider's privacy terms.
Permissions
- Internet / network state: used to load ads and check purchases.
- Microphone: used only while you use a voice command.
- Vibration: optional key feedback.
- Advertising ID: used by AdMob for advertising.
Children's privacy
CalcMate is not directed at children under 13 and does not knowingly collect personal information from them.
Your choices
You can clear your history, turn history off, change ad privacy choices, revoke microphone permission, or uninstall the app at any time. Uninstalling removes data CalcMate stored on your device. Exported backup files may remain wherever you chose to save them, so delete those separately if you no longer need them.
