1. Introduction

Charu Calculator ("the App") is an Android calculator and utility application. Depending on the version and features available, the App may provide standard calculations, scientific calculations, calculation history, percentage calculations, conversions, currency conversion and other calculator-related utilities.

This Privacy Policy explains what information the App handles, what information may be processed by third-party services, how information is stored, and the choices available to you.

The App does not require you to create an account or provide your name, email address, phone number or other contact information to use its core calculator functions.

๐Ÿ›ก๏ธ

2. Information We Collect

Charu Calculator itself is designed not to collect or store personal information on our own servers.

  • No account registration or sign-in is required.
  • We do not ask you to provide your name, email address, phone number or postal address.
  • We do not collect your calculation history on our own servers.
  • We do not intentionally collect GPS or precise location information.
  • We do not intentionally collect your contacts, photos, videos, microphone recordings or call logs.
  • We do not operate a separate backend account system for storing your calculator data.
Important: Third-party services integrated into the App, particularly Google AdMob, may process certain information as described in this Privacy Policy and their own privacy policies.
๐Ÿ’พ

3. Data Stored on Your Device

Some App information is stored locally on your Android device so that the App can remember your preferences and provide features such as calculation history.

  • App preferences such as theme and calculator settings.
  • Scientific calculator preferences such as angle-unit settings where applicable.
  • Calculation history stored locally for convenient access.
  • Other local settings required for the App's normal operation.

This locally stored calculator information is not intentionally uploaded to our servers or used by us to identify you.

๐Ÿ’ก Your control: You can clear available calculation history from the App, and uninstalling the App removes its locally stored App data subject to Android device and backup behavior.
๐Ÿ”“

4. App Permissions

Charu Calculator is designed to request only permissions needed for its available functionality.

The App may use the Android Internet permission to communicate with online services required for certain features and to load advertisements.

The calculator does not require access to your camera, microphone, contacts, call logs or precise location for its core calculator functions.

Note: The exact permissions used by the App may change when new features are introduced. Any material change will be reflected in the applicable App configuration and, where appropriate, this Privacy Policy.

5. Advertising โ€” Google AdMob

Charu Calculator is supported by advertising provided through Google AdMob, a service provided by Google.

Google Mobile Ads SDK may process information such as device identifiers, advertising identifiers, IP address, approximate location information, app interactions and other information permitted under Google's advertising technologies in order to deliver, measure, prevent fraud in, and improve advertising.

The information processed by Google AdMob is governed by Google's applicable policies and terms. Charu Calculator does not receive or store your calculation history through AdMob.

  • Advertising may be personalized depending on your device, account and applicable Google advertising settings.
  • You can manage advertising personalization through your Android or Google advertising settings where available.
  • Ad serving and measurement may involve network communication.

For more information about how Google handles information, please review Google's Privacy Policy .

Important: Google AdMob is a third-party service. Its data practices are controlled by Google and may change independently from this App.

6. Internet & Network Features

The basic calculator functions are designed to perform calculations locally on your device.

However, not every feature necessarily works offline. Features that depend on current or externally provided information, such as currency conversion or exchange-rate information where available, may require an internet connection.

The App may also use an internet connection to request and display advertisements through Google AdMob.

๐ŸŒ Offline use: Core calculations may remain available without an internet connection, but online-dependent features and advertisements may not work or may show limited functionality when you are offline.
๐Ÿ”

7. Data Security

We take reasonable measures to protect information handled directly by the App. Calculator preferences and calculation history are designed to remain within the App's local storage unless a specific Android system feature or user action causes otherwise.

  • Calculation history is stored locally by the App.
  • We do not maintain a server-side database of your calculation history.
  • Network requests made by third-party services such as Google AdMob are handled using their applicable security mechanisms.
  • No method of electronic storage or transmission can be guaranteed to be completely secure.

8. Children's Privacy

Charu Calculator does not intentionally request personal information directly from children.

The App does not require an account or ask users to submit their name, email address or other personal information in order to use the core calculator functionality.

Because advertising services may have their own rules for child-directed users, families should review Google's applicable advertising and privacy policies when using the App.

If you believe that a child has provided personal information to us directly, please contact us so that we can review the situation and take appropriate action.

๐Ÿ•น๏ธ

9. Your Choices & Rights

You remain in control of the information stored locally by Charu Calculator.

  • Clear history: Delete available calculation history from within the App.
  • Remove local App data: You can clear the App's storage through Android settings where supported.
  • Uninstall: You can uninstall the App to remove its local application data, subject to Android backup behavior.
  • Advertising choices: You can manage available advertising personalization controls through your Android or Google settings.
  • Contact us: You can contact us with privacy-related questions or requests using the contact information below.
Because we do not maintain a server-side database containing your calculation history or a user account, there is generally no server-side calculation record for us to export or delete.

10. Changes to This Privacy Policy

We may update this Privacy Policy when the App's features, data practices, third-party services or applicable requirements change.

When we make changes, we will update the "Last updated" date shown at the top of this page. Significant changes may also be highlighted within the App or through another appropriate notice.

We encourage you to review this Privacy Policy periodically so that you understand how the App handles information.
