Privacy Policy

This privacy policy applies to the Fraction Pro app (referred to as the "Application") for mobile devices, created by ProDirt LLC (referred to as the "Service Provider"). The Application is provided "AS IS".

Information Collection and Use

On-Device Data

Fraction Pro is a calculator. The only data it works with is the calculations you enter and your calculation history. This information is stored locally on your device and is never transmitted to the Service Provider or any third party.

No Account Required

The Application does not require you to create an account or provide any personal information such as your name, email address, or phone number. You can use every free feature without identifying yourself in any way.

Permissions

Fraction Pro does not request access to your location, camera, contacts, microphone, or photos. It needs no special device permissions to perform calculations.

Data We Do Not Collect

• Your name, email, or contact information
• Advertising identifiers
• Location data
• Usage behavior or analytics
• Any information shared with third parties for advertising

In-App Purchases

Fraction Pro is free to use as a calculator. An optional one-time in-app purchase unlocks the Common Core teaching method in the "Show Your Work" feature. This purchase is processed entirely through Google Play. The Service Provider does not collect, process, or store any payment information such as credit card numbers or billing addresses — all payment handling is performed by Google Play.

Third Party Services

The Application uses the following third-party service:

• Google Play Services / Google Play Billing — Used for app distribution and to process the optional one-time in-app purchase. Google Privacy Policy →

Data Retention and Deletion

All calculation history and app settings are stored locally on your device. You can remove this data at any time by:

• Clearing the calculation history within the Application
• Going to Settings → Apps → Fraction Pro → Storage → Clear Data
• Uninstalling the Application

The Service Provider does not retain any of your data on external servers, because none is collected.

Children

Fraction Pro is suitable for students, parents, teachers, and tradespeople, and is designed to be used as a learning aid. The Application does not knowingly collect personal information from children under the age of 13. Because the Application collects no personal data at all and requires no account, no personal information from any user — child or adult — is gathered. If you are a parent or guardian and have any questions, please contact us at prodirt.co@gmail.com.

Security

Because all data remains on your device and is never transmitted to external servers, your calculation history is protected by your device's own security measures.

Changes to This Policy

This Privacy Policy may be updated from time to time. Any changes will be reflected on this page with an updated effective date. Continued use of the Application after changes constitutes acceptance of the updated policy.
