DupBook TM

Effective date: July 5, 2026

DupBook is a duplicate bridge personal scoring app published by DupScore LLC ("we," "us," or "our"). This policy explains how DupBook handles your information. In short: DupBook does not collect, transmit, or store any personal information about you on our servers.

Information We Collect

None. We do not collect, receive, or have access to any personal information about you or your use of the app. DupBook has no accounts, no login, and no analytics or advertising tracking.

Information You Enter in the App

DupBook lets you optionally enter information to make scoring easier — such as player names, and if you choose, a player's email address or cell phone number. This information:

• Is entirely optional — player names can be replaced with player numbers, and contact details are not required to use the app.

• Is stored only on your device. DupBook does not use iCloud sync, so your data does not automatically transfer to other devices.

• Is never sent to us or to any third party. We cannot see it.

If you have iCloud Backup enabled in iOS Settings, your device's standard backup may include DupBook's data. That backup is Apple's service, controlled entirely by you.

Subscriptions and Purchases

DupBook offers optional auto-renewing subscriptions. All purchases are processed by Apple through the App Store. We never receive or store your payment card details or Apple Account credentials. Apple provides us only with anonymized, aggregated sales information. Apple's handling of your purchase is covered by Apple's Privacy Policy.

Data Sharing and Selling

We do not sell, rent, share, or disclose your information to anyone — because we do not collect any.

Third-Party Services

DupBook does not integrate any third-party analytics, advertising, or tracking services.

Children's Privacy

DupBook does not knowingly collect any information from anyone, including children.

Changes to This Policy

We may update this policy from time to time. Changes will be posted on this page with a revised effective date.
