  • ZLK Games has no servers of its own; anonymous gameplay statistics and crash reports are collected through Google Firebase to improve the game and are never used for advertising.

Information stored on your device

Level progress, stars, hint balance (Light), language and sound settings and the date of your daily reward are kept in your device's local storage so the game works. This information never reaches us and is deleted when you uninstall the game.

Gameplay statistics and crash reports (Google Firebase)

We use Google Firebase Analytics and Firebase Crashlytics to improve the game. They collect:

  • A random app instance ID (not linked to your name or any account)
  • Gameplay events: level start and finish, move count, stars, hint use, island unlocks, sharing, rewarded ads watched
  • Device model, operating system, language, app version and the approximate country derived from the IP address
  • If the game crashes: the error trace and device state at that moment (memory, orientation, last level opened)

This data is used only to see which levels are hard and to fix bugs; it is not used for advertising and is not linked to your advertising ID. Google Analytics data is deleted after 14 months. More: Firebase and privacy.

Advertising

Rewarded ads are delivered by Google AdMob. When an ad is shown, these services may collect the following directly from your device:

  • Advertising ID (Android Advertising ID / Apple IDFA — only with your permission)
  • IP address and the approximate location derived from it (country/city level)
  • Device model, operating system version, language and app information
  • Ad interactions (impressions, views, clicks)

This data is used to serve and measure ads, prevent fraud and, with your consent, personalize ads. Users in the European Economic Area, the United Kingdom and Switzerland are asked for consent on first launch; on iOS the App Tracking Transparency prompt is shown. Without consent, non-personalized ads are shown.

Ad partners' privacy policies: Google.

In-app purchases

Purchases are processed entirely by Google Play or the Apple App Store. We never see or store your payment details; the game only receives confirmation that a purchase was made.

Replay videos and challenge links

A level replay video is created on your device and is shared only if you tap Share, through the app you choose; it is never sent to us. Challenge links contain only the level number and move count, no personal data.

Children

Prism Valley is not directed at children under 13 and we do not knowingly collect personal data from them.

Your rights

You may contact us to exercise your rights under the GDPR and similar laws (information, access, correction, deletion, objection). As we hold no personal data about you, requests about advertising data can be sent directly to the ad partners. You can reset or delete your advertising ID and turn off personalized ads in your device settings (Android: Settings › Google › Ads; iOS: Settings › Privacy & Security › Tracking).

Changes

If we update this policy, we will publish the new version on this page and change the effective date.
