Privacy Policy

Privacy Policy for the Numetra calculator and converter application.

Last updated: September 24, 2026

1. Introduction

Welcome to Numetra. Numetra is a calculator and converter application designed to provide everyday calculation and conversion tools.

This Privacy Policy explains how Numetra handles information when you use the application.

By using Numetra, you acknowledge the practices described in this Privacy Policy.

2. Information Stored Locally on Your Device

Numetra provides features that store certain information locally on your device.

This may include:

  • Calculation history
  • Favorite calculators or converters
  • Theme preferences, such as light, dark, or system theme
  • Haptic feedback preference
This information is stored locally on your device and is not transmitted to Numetra servers as part of the application's normal functionality.

3. Advertising

Numetra is supported by advertising.

The application uses Google Mobile Ads to display advertisements, including banner and interstitial advertisements.

Google Mobile Ads is provided by Google and may collect certain information from your device and your interactions with the application in order to provide, measure, maintain, and protect advertising services.

4. Information Collected Through Google Mobile Ads

Depending on the applicable configuration, Google Mobile Ads may automatically collect or share information such as:

  • IP address
  • Device and advertising identifiers
  • App or device-related identifiers
  • Information about interactions with the application
  • Advertising interactions
  • Diagnostic and performance information
  • Information used for fraud prevention and security

Google states that information collected by the Google Mobile Ads SDK is encrypted in transit.

For more information about Google's handling of information, please review Google's privacy documentation:

Google Privacy Policy

Information about Google Mobile Ads and Google Play data disclosure can also be found in Google's developer documentation.

5. Non-Personalized Advertising

Numetra currently requests non-personalized advertisements from Google Mobile Ads.

Non-personalized advertisements are not selected based on a user's previous activity for personalized advertising.

However, non-personalized advertising does not mean that no information is processed. Certain information may still be processed for purposes such as ad delivery, frequency capping, aggregated reporting, security, and fraud prevention.

6. How We Use Information

Information handled by Numetra or its service providers may be used for the following purposes:

  • Providing calculator and converter functionality
  • Saving your local preferences and calculation history
  • Displaying advertisements
  • Measuring advertising performance
  • Maintaining application and advertising functionality
  • Detecting and preventing fraud or abuse
  • Diagnosing technical and performance issues
  • Improving reliability and user experience

7. Information Sharing

Numetra does not sell your locally stored calculation history, favorites, or application preferences.

Information may be processed or shared by third-party service providers when necessary to provide their services to the application.

In particular, Google Mobile Ads may collect and share information as described in Google's documentation for advertising, analytics, security, and fraud prevention purposes.

We may also disclose information where required by applicable law, legal process, or to protect the rights, safety, and security of users or the application.

8. Data Retention and Deletion

Local application data

Calculation history and other locally stored preferences remain on your device until you delete them, clear the application's storage, uninstall Numetra, or otherwise remove the stored data.

Numetra provides a "Clear History" feature that allows you to delete your saved calculation history from within the application.

Advertising-related information

Information processed by Google Mobile Ads is handled according to Google's applicable policies, retention practices, and user controls.

Please refer to Google's Privacy Policy for additional information.

9. Data Security

Numetra is designed to minimize the information that it directly stores and processes.

Information stored by Numetra locally remains on your device unless another service or operating-system feature processes it.

Data transmitted by Google Mobile Ads is handled using security measures described by Google, including encryption in transit.

10. Children's Privacy

Numetra is not specifically directed toward children under the age required by applicable laws.

We do not knowingly collect personal information directly from children through Numetra.

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

11. Third-Party Services

Numetra uses third-party services to provide certain functionality, including advertising.

The primary third-party service currently used by Numetra is:

  • Google Mobile Ads

Third-party services operate under their own privacy policies and terms. We recommend reviewing the applicable policies of these providers.
