1. Who we are

The data controller is Zuki Apps. Contact details are at the end of this Policy.

This Policy applies to the Contacts Toolbox app and the legal pages we publish for the product.

2. Information we collect

Contacts Toolbox is designed to work on-device. Contact data is processed locally.

• Contact records you choose to organize, processed on device (not uploaded to Zuki Apps)
• Groups, match suggestions, edit history, and Premium status stored on device
• Advertising identifier and ad performance data via Google AdMob (if you allow tracking on iOS)
• Crash and diagnostic data via Firebase Crashlytics
• Feedback and support messages you send
• Purchase records handled by Apple or Google — tokens only, not full card data

3. How we use information

We use information to:

We do not sell your personal information.

• Organize and deduplicate contacts on your device
• Operate and improve Contacts Toolbox
• Respond to support requests
• Validate in-app purchases

4. Advertising and tracking

The free version shows Google AdMob ads. On iOS we ask for App Tracking Transparency permission before initializing ads. You can deny tracking; ads may still appear in a non-personalized form.

We do not upload your address book to Zuki Apps servers. Premium removes ads.

5. Storage and retention

Contact edits and history remain on device until you uninstall or clear them.

Ad and purchase partners retain data under their own policies.

6. Third-party services

Apple App Store, Google Play Billing, Google AdMob, and Firebase (Analytics and Crashlytics) process data under their own policies.

We do not sell your personal information or your address book.

7. Your rights and children

Depending on your jurisdiction, you may have rights to access, correct, delete, or object to certain processing. Contact us to exercise rights.

Contacts Toolbox is a general-audience utility. It is not directed to children under 13.

8. Changes

We may update this Policy from time to time. We will post the revised version with a new Last updated date.
