4. Advertising in Our Mobile Applications

Some of our mobile applications offer free-tier access supported by third-party advertising. We display the following types of advertisements within our apps:

4.1 Ad Formats Used

  • Splash / Open Screen Ads: Full-screen advertisements displayed when the app is first launched or brought to the foreground. These appear for a limited time (typically 3–5 seconds) and can be dismissed by the user. Splash ads may be static images, animated graphics, or video.
  • Rewarded Video Ads: Optional video advertisements that users may choose to watch in exchange for in-app rewards, premium feature access, or extended trial usage. Users explicitly opt in to watch rewarded video ads and may decline at any time.
  • Interstitial Ads: Full-screen advertisements displayed at natural transition points in the app (e.g., between levels, after completing a task, or when navigating between sections). Interstitials can be closed after a short delay.
  • Banner Ads: Smaller rectangular advertisements displayed within the app interface, typically at the top or bottom of the screen. Banner ads are non-intrusive and remain visible while users interact with app content.

4.2 Personalized vs. Non-Personalized Ads

By default, ads served through our advertising partners may be personalized based on your interests, prior browsing behavior, and demographic information collected by those partners across their ad networks. You have the right to opt out of personalized advertising. Instructions for doing so are provided in Section 22 (Your Privacy Rights).

Where required by applicable law (e.g., GDPR, CCPA), we present users with a consent mechanism before serving personalized advertisements. If you deny consent, only non-personalized (contextual) ads will be shown.

Advertising ID Reset: You can limit ad tracking at any time by resetting your device's Advertising ID (on Android: Settings > Privacy > Ads; on iOS: Settings > Privacy & Security > Tracking) or by enabling "Limit Ad Tracking" on iOS / "Opt out of Ads Personalization" on Android.

6. App Store Privacy Requirements

6.1 Apple App Store — App Privacy Nutrition Labels

Our applications published on the Apple App Store include Apple-required "App Privacy" nutrition labels that summarize what data each app collects and how it is used. Categories we disclose in accordance with Apple's guidelines include:

  • Data Used to Track You: Advertising ID (IDFA), usage data shared with advertising networks for cross-app tracking
  • Data Linked to You: Contact information (if account created), usage data associated with your account
  • Data Not Linked to You: Crash logs, performance data, advertising data without direct user identity linkage

In compliance with Apple's App Tracking Transparency (ATT) framework, our apps display the standard iOS permission prompt before accessing the IDFA for advertising purposes. You may deny this permission at any time without losing access to core app functionality.

6.2 Google Play — Data Safety Section

Our applications published on Google Play include a completed Data Safety section disclosing:

  • Data collected: App activity (in-app interactions, search history), device identifiers, approximate location, app info and performance (crash logs)
  • Data shared: Advertising IDs and app event data shared with advertising SDK partners (listed in Section 5)
  • Security practices: Data encrypted in transit using TLS; users can request deletion of account-associated data
  • Commitment to Play Families Policy: Apps designated for children comply with Google Play's Families Policy and do not serve non-family-safe ads

  • Child-directed apps do not collect persistent device identifiers for advertising purposes
