Your privacy matters to us. This Privacy Policy explains how Kwarks (“the Game,” “we,” “us,” or “our”) handles your information when you play our game.

1. Information We Collect

The Game itself does not collect any information.

The game is solely a set of abstract reasoning tests consisting of a series of 5x5 grid matrices. Your answers are not stored anywhere, your results are purely displayed on the screen without any further propagation of data beyond the user's device.

However, the app uses Google AdMob, a third-party advertising library may collect some data for the purposes of advertising listed below.

Data types collected by AdMob

  • Identifiers: advertising identifier (IDFA), device identifiers, and other identifiers used for advertising and analytics.
  • Usage & Interaction Data: in‑app events, ad impressions, clicks, ad viewability and engagement metrics.
  • Diagnostics: crash logs, performance data, error reports, and related technical information.
  • Device & Network Information: IP address, device model, operating system version, browser type, and network information.
  • Location: coarse location (city/region) when available and only if enabled; precise location only if you explicitly grant location permission.
  • Other signals: anonymized signals and hashed identifiers used for ad selection and measurement.

Purposes of collection

  • Serve and personalize ads based on inferred interests and app usage.
  • Measure ad performance, impressions, clicks and conversions.
  • Prevent fraud and improve ad quality and relevance.
  • Diagnostics and product improvement (stability, performance).

Sharing and third parties

  • Data collected by AdMob may be shared with Google’s advertising partners, measurement providers, and other third parties involved in ad delivery and analytics.
  • Advertisers and third parties may use identifiers and signals to deliver and measure ads across apps and websites.

Tracking and user choices

  • AdMob may be used to track users across apps and websites for advertising purposes. This tracking is subject to Apple’s App Tracking Transparency (ATT) prompt on iOS.
  • On iOS, Kwarks will request permission to track via the system ATT prompt when required. If you decline, AdMob will not use the device’s advertising identifier for cross‑app tracking.
  • You can control or opt out of personalized ads:
  • On iOS: Settings → Privacy → Tracking → disable “Allow Apps to Request to Track,” or turn off tracking per‑app.
  • Google Ads Settings: https://adssettings.google.com
  • For general interest‑based advertising controls, see Google’s privacy resources: https://policies.google.com/technologies/ads

Data retention and security

  • AdMob and its partners retain data according to their own policies. Kwarks does not control third‑party retention policies.
  • We do not sell personal data as defined under applicable laws; data may be shared with advertising partners for ad delivery and measurement.

2. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated date.
