Privacy Policy

The data controller is Ukkio Games, reachable at the following email address:

This policy applies to the mobile application Prism Blocks (bundle ID: io.ukkio.prismblocks), available on the App Store and Google Play.

Prism Blocks collects only anonymous and aggregated data necessary for the app to function and improve. No directly identifiable personal data is collected by the application.

Data collected includes:

• Anonymous analytics (Firebase Analytics): gameplay events, game sessions, features used, country of origin (aggregated). No data is linked to an identifiable user.
• Crash reports (Firebase Crashlytics): technical error information, app version, device model (anonymized) in the event of a crash. Essential for bug resolution.
• Performance metrics (Firebase Performance): load times, operation latency. Aggregated technical data, not personal.

Prism Blocks uses Google AdMob to display advertisements. The service may use the device's advertising identifier to personalize ads.

• iOS (IDFA): before accessing the advertising identifier, the app requests explicit consent via Apple's App Tracking Transparency (ATT) framework. Without consent, only non-personalized contextual ads are shown.
• Android (GAID): users in the European Union and European Economic Area are asked for explicit consent under GDPR before personalized ads are shown. Consent can be revoked in the app settings.

AdMob's data collection practices are governed by Google's Privacy Policy.

The app uses the following third-party services, each of which has its own privacy policy:

You also have the right to lodge a complaint with your national data protection authority or the supervisory authority competent in your country of residence.

Data collected by Firebase services is retained according to Google's policies:

• Firebase Analytics: usage data is retained for a default period of 14 months, after which it is automatically deleted. The period is configurable in the Firebase project settings.
• Firebase Crashlytics: crash reports are retained for 90 days.
• Firebase Performance: performance data is retained for 30 days.

Data stored locally on the device (high score, settings) remains on the device until the app is uninstalled and is not transmitted to any servers we own.

We reserve the right to modify this policy at any time. Material changes will be communicated via:

• An app update on the stores (App Store / Google Play) with release notes indicating the changes
• An update to the "Last updated" date at the top of this page

By continuing to use the app after changes are published, you accept the updated version of the privacy policy. We encourage you to review this page periodically to stay informed.

For any question, concern or request regarding this privacy policy or the processing of your personal data, please contact us:

We are committed to responding to all requests within 30 business days of receipt.
