Evil Merge: Match Game

Summary

• No sign-up is needed. Progress is saved on your device and, so it is not lost when you change phones, as a cloud backup tied to an automatically created anonymous account (Google Firebase). You may optionally sign in with Google or Google Play Games to carry your progress to another device. We do not collect analytics.
• Optional in-app purchases are processed by Google Play. We never see your card or bank details.
• The game shows ads from Google AdMob: rewarded ads only when you choose to watch one, and occasional full-screen ads after a finished round (not for players who bought “Remove Ads”). AdMob collects device information such as your advertising ID to show and measure ads.
• We do not sell personal information.

1. Information stored on your device

The game keeps its save in private app storage: progress, currencies, items, upgrades, collection, settings, daily counters for ads, and purchase records (product ID and purchase token) used to deliver each purchase once and to restore it. It stays on your device until you reset it, clear the app’s storage or uninstall the game. If Android backup is enabled on your device, the save may be included in your Google backup under Google’s settings.

2. Cloud save and optional sign-in (Google Firebase)

When the game is online it creates an anonymous account with Google Firebase Authentication (a random user ID) and stores a copy of your save (the same data as above, plus a save time and a progress number) in Google Cloud Firestore so it can be restored. If you choose “Sign in with Google”, Google shares your Google account name, email address and profile picture with the game and Firebase links your Google account to that user ID; if you choose Google Play Games sign-in, your Play Games player identity is linked the same way. We use this only to find and restore your save on another device and show which account is connected; we do not send you email or share it with anyone. Data is sent encrypted (HTTPS). You can delete the cloud save and the account at any time in Settings › Account › “Delete online data”, or by emailing us; the save on your device stays until you reset it or uninstall the game. Firebase is operated by Google (firebase.google.com/support/privacy).

2-1. Error reports

If the game hits an error or closes unexpectedly, it sends an error report to our Firebase project so we can fix it: the error message and where it happened in the game code, the game screen, game version, device model, Android version, graphics chip, memory use, frame rate, language setting, time, your online user ID, and the last few lines of the game’s own log. Reports contain no save contents, name or email, are readable only by the developer, and are deleted after 90 days.

3. In-app purchases (Google Play)

Purchases (gem packs, Starter Pack, Remove Ads, Piggy Bank) are handled by Google Play under Google’s terms and privacy policy (policies.google.com/privacy). Google gives the game a purchase record (order, product, time, token); the game uses it to deliver the item and confirms delivery back to Google Play. As the developer we receive Google Play transaction reports (for example order number, item, price, date, country) and use them only for accounting, tax, refunds and fraud prevention.

4. Advertising (Google AdMob)

The game uses the Google Mobile Ads SDK (Google LLC). To serve, limit, measure and protect ads it may collect device identifiers including the advertising ID, IP address, approximate location derived from it, device and app information, and ad interaction data. Where required (for example in the EEA, UK and Switzerland) the game asks for consent through Google’s User Messaging Platform before personalised ads are shown. You can reset or delete your advertising ID or opt out of ad personalisation in Android Settings › Google › Ads. Google’s use of this data is described at policies.google.com/technologies/partner-sites.

5. Children

The game is not directed at children under 13 and we do not knowingly collect personal information from them.

6. Support requests

If you email us, we receive your address and what you send, and use it only to answer you.

7. Changes

If data handling changes, this page and the Google Play data-safety section will be updated before the change ships.

iPhone (App Store) version

On iPhone, purchases of the Starter Pack, Magic Stone packs and Open Piggy Bank are processed by Apple through the App Store under Apple's terms and privacy policy; we never receive your payment details. The iPhone version shows no ads, contains no advertising SDK and does not track you. Google sign-in and Google Play Games are not offered on iPhone; the anonymous cloud save, error reports and deletion (Settings › Delete online data) work the same way. Refunds for App Store purchases are requested from Apple at reportaproblem.apple.com.
