2. Information stored on your device
The following information is stored on your device and is not sent to the developer's server.
- Game progress: hero and summon shards and grades, gear, charm books, stage records, gold and other resources, mailbox status
- Settings: music and sound effects, language, display options, battle speed, damage number display
- The time you agreed to the Terms of Service and this Privacy Policy on first launch
Uninstalling the app deletes this information. Progress cannot be moved to another device.
3. Information sent to external services
| Service | Provider | Information sent | Purpose |
|---|---|---|---|
| Google AdMob | Google LLC | Advertising identifier, approximate location estimated from IP address, ad impressions and views, device and app performance information | Showing rewarded ads and counting them. Personalized ads follow your consent result (section 4) |
| Firebase Analytics | Google LLC | App instance ID, advertising identifier, screen names (lobby tab names, battle), the events below | Usage statistics and game balance review |
| Firebase Crashlytics | Google LLC | Error type and message, short values describing the situation, device model, OS version, installation identifier | Finding and fixing app errors |
| Firebase Remote Config | Google LLC | Basic device information Firebase processes when downloading settings (country and language codes, time zone, OS version) | Adjusting game values without an app update |
| RevenueCat | RevenueCat, Inc. | Purchase history, anonymous user ID | Purchase verification, restore, subscription status |
| Google Play, Apple App Store | Google LLC, Apple Inc. | Payment information and receipts (processed directly by the store) | In-app purchases and refunds |
Events sent to Firebase Analytics
The app sends only the events and values below. It does not send names, typed text, or device identifiers.
| Event | Values sent |
|---|---|
| stage_start | Mode (normal or abyss), stage or floor number |
| stage_end | Mode, stage or floor number, result (win or loss), wave number |
| card_pick | Wave number, whether a synergy card was picked |
| ad_reward | Where the rewarded ad was watched (win double, card refresh, daily shop, stamina charge) |
| shop_view | None (only that the shop screen was opened) |
| daily_claim | Type of daily shop item claimed |
Firebase and RevenueCat record completed purchases automatically. The app does not send them separately.
4. Ad consent and withdrawal
First launch
On first launch you must agree to the Terms of Service and this Privacy Policy before you can start playing. The app stores the time of your agreement on your device.
Ad consent
In regions that require ad consent, Google's consent form (UMP) appears. If you do not allow personalized ads, you will see non-personalized ads. The advertising identifier is also used to count ad impressions and prevent invalid clicks.
To change your choice, press Consent settings in the settings popup.
The app sends the game events in section 2 to Firebase Analytics only when your consent allows ad requests. Error reports, screen names, and the basic data Firebase collects on its own (such as first open and app usage time) are sent regardless of consent.
You can also reset or delete the advertising identifier in your device settings to limit ad tracking.
On iOS, the app asks for tracking permission once, the first time you watch a rewarded ad. If you allow it, AdMob can use the iOS advertising identifier; if you decline, it cannot. The game works the same either way, and you can change the choice in iOS Settings > Privacy & Security > Tracking.
5. Retention and deletion
- Information on your device is deleted when you uninstall the app.
- External services keep information under their own policies. You can change ad personalization in your Google ad settings.
- The developer does not store user information on a server, so there is no developer-held data to delete.
- Purchase records are kept by the store and RevenueCat. See your store account or the RevenueCat privacy policy.
6. Service providers and international transfers
The Developer uses the companies below for ads, analytics and crash reports, and purchase checks. They are in the United States, and while you use the app the information in section 3 is sent to the United States. Each company handles the data only for these tasks under its own terms and data processing conditions.
| Provider (recipient) | Task | Country | Information | Timing and method | Retention |
|---|---|---|---|---|---|
| Google LLC (AdMob) | Rewarded ads, ad consent | United States | AdMob items in section 3 | Network transfer when an ad is requested | As stated in Google's policy (https://policies.google.com/privacy) |
| Google LLC (Firebase) | Remote settings, analytics, crash reports | United States | Firebase items in section 3 and the Analytics events | Network transfer during app use | As stated in Google's policy (https://policies.google.com/privacy) |
| RevenueCat, Inc. | Purchase checks and restore | United States | Purchase history, anonymous user ID | Network transfer during purchase checks and restore | As stated in RevenueCat's policy (https://www.revenuecat.com/privacy) |
Google Play and the Apple App Store process payments directly. The Developer never receives payment details such as card numbers. If you do not want your data transferred, stop using and uninstall the app. You will then be unable to use the Game.
7. Children
The app is intended for users aged 12 and older. It is not made for children, and it does not ask for sign-ups, names, or contact details.
