Introduction

This Privacy Policy applies to the CalcuGo mobile application ("Application"), developed by Mikael Tenshio. The Application is provided "AS IS" and includes:

  • Basic Calculator
  • Unit Converter
  • Date Calculator

CalcuGo does not require accounts, logins, or registration. Calculation inputs, history, favorites, and preferences are stored locally where those features are used. They are not sent to a developer server or included in advertising or analytics services.

Local Data

CalcuGo does not intentionally collect personal data through developer-operated servers. The current native app does not include advertising SDKs, analytics SDKs, crash-reporting SDKs, or personal profiling. The app can save the following information locally on your device when you use related features:

  • Calculator expressions, results, timestamps, and pinned history items
  • Conversion history, date-tool history, and favorite units
  • Appearance, precision, separator, motion, haptic, and sound preferences

This local data is used only to make the app remember your preferences and recent work on the same device.

Data Retention & Deletion

Locally stored histories, favorites, and settings remain on your device until you clear them, reset app data, or uninstall CalcuGo. The app does not keep a developer-side copy.

Android may include compatible app preferences and local history in device backup or device transfer if those system features are enabled in your device settings. You can manage or remove local app data through CalcuGo's history tools or Android system settings.

Permissions Used
  • No Internet permission - calculations, conversions, and date tools work offline.
  • No personal content permissions - no contacts, media, messages, camera, microphone, location, or personal file access is requested.

System backup and device-transfer behavior is controlled by Android settings.

Children's Privacy

CalcuGo is not intended for children under the age of 13. Because the app has no account system, advertising SDK, or analytics SDK, it does not knowingly collect personal information from children.
