Introduction

Welcome to Calculator Pro ("we", "our", "the App"). We are committed to protecting the privacy of every person who uses our application.

Calculator Pro is a free, ad-supported calculator application. This Privacy Policy explains what information is collected by our advertising partners, how the app works, and your rights as a user.

02

Information We Collect

Calculator Pro itself does not collect, store, or transmit any personal information. The app does not require an account, login, or any form of registration.

Advertising Partner (Google AdMob):

This app displays advertisements served by Google AdMob, a third-party advertising service. AdMob may collect certain information to provide personalized ads, including:

  • Device information (device model, operating system version)
  • Advertising ID (a unique identifier for advertising purposes)
  • IP address (to determine approximate location)
  • App usage data (interactions with ads)
  • Crash logs and diagnostic data (for ad performance)
This data is collected and processed by Google, not by us. We do not have access to your personal information collected by AdMob.

Calculation History

The Standard and Scientific calculator modes save your calculation history locally on your device using an SQLite database built into Android.

  • History data never leaves your device
  • Not uploaded, synced, or backed up to any server
  • You can view and clear your history at any time from within the app
  • Uninstalling the app permanently removes all stored history
05

App Permissions

Calculator Pro requires the following permissions to function:

  • INTERNET — Required to load and display advertisements from Google AdMob
  • AD_ID — Used by Google AdMob to serve personalized advertisements based on your interests

The app does not access your camera, microphone, contacts, location (GPS), storage, or any other sensitive system resources. These permissions are used solely for advertisement delivery by Google AdMob.

06

Third-Party Services

Calculator Pro uses Google AdMob for advertising. AdMob is a third-party service that may collect and process data as described in their privacy policy.

Data Sharing

We do not collect or share any personal data ourselves. However, Google AdMob, as a third-party advertising partner, may share anonymized data with advertisers for ad targeting and measurement purposes, as described in Google's Privacy Policy.

Your calculation data, history, and preferences remain entirely on your device and are never transmitted to us or any third party.

08

Suitable for All Ages

Calculator Pro is appropriate for users of all ages. While the app displays advertisements, we use Google AdMob's family-safe ad filtering to ensure age-appropriate content is shown.

The app does not contain in-app purchases or external links outside of advertisements. We do not knowingly collect personal information from children under 13. Ads shown are subject to Google's ad policies and content guidelines.

Your Choices

You have the following options regarding advertising:

  • Reset your Advertising ID — This will reset the identifier used by AdMob to show you relevant ads

Note: Opting out of personalized ads means you will still see ads, but they may be less relevant to your interests.
