• Purchase History: Through RevenueCat and Google Play Billing, we track the status of your subscriptions (e.g., "Pro Version") and your purchase history. We do not collect your credit card numbers; we only receive a cryptographic token verifying the purchase.

4. THIRD-PARTY DATA SHARING AND SERVICE PROVIDERS

We do not sell your personal data in the traditional sense (i.e., exchanging your name and email for money). However, we share data with trusted third-party service providers to facilitate app functionality, analytics, and advertising. Under certain laws (like the CCPA), sharing unique identifiers for advertising may be classified as a "sale."

• Data Shared: Device ID, IP Address, Crash Logs, App Usage Data.

• Purpose: To improve app stability and user experience.

6. UNITED STATES PRIVACY RIGHTS (CCPA, CPRA, VCDPA)

This section provides specific disclosures required by the California Consumer Privacy Act (CCPA), the California Privacy Rights Act (CPRA), and the Virginia Consumer Data Protection Act (VCDPA).

6.1 Right to Know About Personal Data Sales You have the Right to Know whether your personal data is sold.

• Disclosure: Tz Studios does not sell your personal contact information (such as your name, email address, or phone number) to third-party data brokers for monetary consideration. However, we allow third-party advertising partners (specifically Google AdMob) to collect unique identifiers (such as your Advertising ID) and usage data through our Application. Under the broad definition of "sale" in the CCPA/CPRA, this activity may be considered a "sale" of data.

6.2 Right to Know About Personal Data Sharing You have the Right to Know whether your personal data is shared with third parties.

• Disclosure: We share your personal information (specifically Device IDs, Advertising IDs, and IP addresses) with third-party service providers (Google Firebase, RevenueCat, Supabase) for business purposes and with advertising networks (Google AdMob) for cross-context behavioral advertising purposes.

6.3 Right to Opt-Out of Data Sale and Sharing You have the Right to Opt-Out of the "sale" or "sharing" of your personal information for cross-context behavioral advertising.

6.4 How to Opt-Out of Data Sale and Targeted Ads Since we do not maintain a direct database of user profiles for sale, "opting out" in the context of our Application means preventing your Advertising ID from being used for targeted ads. You can exercise your Right to Opt-Out by following these specific steps on your mobile device:

• For Android Devices:

  1. Open your device Settings.

  2. Navigate to Google > Ads (or Privacy > Ads depending on your OS version).

  3. Select "Delete advertising ID" or toggle "Opt out of interest-based ads."

  4. Result: This action prevents Google AdMob from using your specific Advertising ID to build a profile about you or show you personalized ads within our Application.

If you wish to make a formal request regarding other data (such as your email address), please contact our Data Protection Officer at tzstudios.dev@gmail.com with the subject line "Do Not Sell My Personal Information."
