Privacy Policy

Effective date: October 10, 2026

✓ Data Not Collected

MarginKeeper does not collect, store, share, or sell personal information through the app. There are no accounts, no analytics, no advertising, and no tracking. The numbers you enter and the calculations you perform stay on your device.

Who we are

MarginKeeper is published by John Dexter in the United States. This privacy policy covers the MarginKeeper app and the website at marginkeeper.com.

The app

MarginKeeper does not collect data from the app. It does not require an account and does not contain analytics, advertising, or tracking software. The information you enter is processed on your device and is not transmitted to John Dexter or third parties.

Because MarginKeeper does not collect or retain user data from the app, there is no app user data held by MarginKeeper to access, correct, or delete.

Purchases

MarginKeeper is sold through Apple's App Store. Purchases are processed by Apple under Apple's own privacy practices. MarginKeeper does not receive your payment details from Apple.

This website

The MarginKeeper website does not use advertising, analytics, or tracking technologies. The website does not intentionally use cookies to identify or track visitors.

The website's hosting provider may process basic technical information, such as IP addresses and browser information, as part of ordinary server operation, security, and reliability. MarginKeeper does not use this information to identify or track individual visitors.

If you contact us

If you contact us at support@marginkeeper.com, we receive the email address and information you choose to include in your message. This information is used only to respond to your request and is not used for advertising or added to a marketing list.

You may request deletion of your support correspondence by contacting support@marginkeeper.com.

Children

MarginKeeper is a business utility and is not directed to children. The app does not collect personal information from its users.

Changes to this policy

If MarginKeeper's privacy practices change, this policy will be updated accordingly. If the app begins collecting data in the future, the App Store privacy disclosures will also be updated before that change is released.
