Chain Reaction Merge · Developed by Ikustaka · Last updated: July 26, 2026
Ikustaka ("we", "us", or "our") built Chain Reaction Merge as a free-to-play Android game. This page informs you of our policies regarding the collection, use, and disclosure of information when you use our game, and the choices you have associated with that information.
Chain Reaction Merge does not require an account, login, or any personal information to play. We do not directly collect your name, email address, location, or any other personally identifiable information.
All game progress (score, achievements, unlocked cosmetics, preferences) is stored locally on your device using Android SharedPreferences. No game data is transmitted to our servers, because we operate no servers.
The game uses Google AdMob to display advertisements. AdMob may collect and process the following data in accordance with its own privacy policy:
This information is used to serve relevant ads and to measure ad performance. We receive only aggregated, non-identifiable revenue and impression statistics.
Chain Reaction Merge displays banner, interstitial, and rewarded video ads served by Google AdMob. Ads may be personalised based on your interests as inferred from your device's Advertising ID.
You can opt out of personalised ads at any time through your device settings:
The game offers a one-time Remove Ads purchase. After purchase, no ad SDKs are invoked and no ad-related data is collected through the game.
The game may send local push notifications (e.g., daily reminders). These notifications are scheduled entirely on your device using Android's WorkManager; no server is involved and no personal data leaves your device to deliver them.
You can disable notifications at any time in your device's app settings: Settings → Apps → Chain Reaction Merge → Notifications.
Chain Reaction Merge is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. Because the game uses Google AdMob — which may collect the Advertising ID — parents or guardians who believe their child has used the game should contact us at the address below and we will take appropriate steps.
Because we collect no personal data ourselves, we hold no personal data that could be breached from our end. All locally stored game data is protected by your device's built-in storage isolation (Android app sandboxing).
If you are a resident of the European Economic Area or California, you may have rights regarding personal data held about you. Since Ikustaka does not itself hold any personal data, requests related to the data collected by Google AdMob should be directed to Google:
This game does not contain links to external websites. If that changes in a future update, this policy will be updated accordingly.
We may update this Privacy Policy from time to time. You are advised to review this page periodically for any changes. Changes are effective when posted on this page. The "Last updated" date at the top of this page will reflect any revision.
