Donut Circuit Privacy Policy
Althea Group Co., Ltd., Bangkok, Thailand · support@altheagroup.net
This policy covers Donut Circuit on iOS and Android. Some features and privacy choices depend on the app version, location, or device settings. The Althea Group website has its own privacy policy. Website Privacy Policy
Accounts, progress and online services
The game saves progress, level and tutorial history, coins, boosters and preferences on your device. When the game connects, Firebase Authentication can create a guest account with a unique game account ID. You can optionally link an Apple or Google account. We use the game account ID and sign-in provider information to verify who owns a save, restore access, switch accounts and secure the service. Linking a new provider account to your guest can keep the same game account and progress. Signing out opens a fresh guest. Save conflicts may require you to choose one complete save.
Where cloud backup is available, Firestore can hold an account-owned gameplay snapshot and information used to track and reconcile its revisions. Eligible guest accounts can also have cloud saves. Recovery requires access to the original owner and a compatible save. If the guest credential is lost or progress has yet to sync, some or all progress may be unrecoverable. Firebase Functions handle online operations such as purchases, rewards and deletion. Firebase App Check helps verify that requests come from a legitimate app installation.
Gameplay Analytics, advertising and privacy choices
Where permitted, Firebase Gameplay Analytics is enabled by default under the consent design implemented for V0.12. It helps us understand how people use the game and where they encounter problems. It can process events such as level attempts and outcomes, booster use, reward interactions and Shop activity, along with app and device information and SDK-managed identifiers. Firebase Crashlytics separately processes crash reports, technical diagnostics and SDK identifiers to help us diagnose errors.
The game uses Google’s User Messaging Platform (UMP) and Firebase Consent Mode. Gameplay Analytics starts paused while UMP resolves the applicable Analytics storage choice. Collection can start if that choice allows it or if UMP confirms a choice is unnecessary and the permitted default applies. Collection stays off if Analytics storage is refused or unresolved. The game also preserves an explicit refusal recorded by a previous version. Earlier 0.12.1 builds 121001 and 121002 had Gameplay Analytics collection off. Verification of the newer consent flow and Analytics delivery on signed iOS and Android devices is pending.
Consent Mode handles four purposes.
| Purpose | What it controls |
|---|---|
analytics_storage | Storage used for Analytics, such as identifiers that help measure use of the app. |
ad_storage | Storage used for advertising, such as advertising-related identifiers. |
ad_user_data | Sending user data to Google for online advertising purposes. |
ad_personalization | Use of data for personalized advertising. |
The three advertising purposes default to denied in Firebase Consent Mode. When Settings → Ad Privacy Choices is available, use it to reopen UMP Privacy Options and change or withdraw the choices shown there, including Analytics storage where the form offers it. The app rechecks the Analytics choice after the form. If you cannot find the option or need help exercising a privacy right, contact us.
On iOS, Apple’s App Tracking Transparency (ATT) controls permission for tracking across other companies’ apps and websites where applicable. You can change that permission in iOS Settings. Ordinary gameplay measurement follows its Analytics storage choice independently. Google AdMob may show rewarded and interstitial ads subject to applicable choices and eligibility. It can process app or device information, ad interactions and advertising identifiers where permitted. Ads may still appear after tracking is declined. For a rewarded ad, our servers verify the signed completion from AdMob and record eligible grants to deliver each earned reward once.
Purchases and notifications
Apple App Store and Google Play handle payments. RevenueCat and our services use game account IDs, product and transaction references, store verification, entitlements and delivery records to fulfill purchases, help with restoration and refunds, and prevent duplicate or fraudulent grants. The stores handle payment-card details. We do not receive your full card details from them.
Settings → Notifications controls the game’s preference. Your device settings control operating-system permission. The game can schedule eligible reminders locally. With the preference and permission enabled, Firebase Cloud Messaging (FCM) registers the installation for remote notifications using a registration token and related installation information. Apple Push Notification service (APNs) delivers remote notifications on iOS. Remote delivery has been observed on iOS and Android. Delivery varies with connectivity, device settings and the operating system. Turning off the game’s preference cancels local reminders and requests remote unregistration when connected. You can also turn off notification permission in your device settings.
Providers and international processing
We share information needed to operate these services, respond to support and rights requests, protect the game and comply with legal obligations. We and our providers may process information outside your country, including in other countries where providers operate.
| Provider | What we use it for | Official privacy information |
|---|---|---|
| Google Firebase | Authentication, Firestore, Cloud Functions, App Check, Analytics, Crashlytics and Cloud Messaging | Firebase privacy and security |
| Google sign-in, Google Play distribution and billing, AdMob and UMP | Google Privacy Policy | |

Support, retention and your rights
If you contact support, we use your email address and the information you choose to share to respond, investigate and verify your request. Our email service helps us handle correspondence. Avoid sending passwords, sign-in codes, tokens or full payment-card details.
We retain account, progress and support data as needed to operate the service and handle requests. Verified account deletion removes the game account and its owned cloud data within the deletion scope. Limited purchase, refund, reward verification, deletion status, security or fraud prevention records may be retained as needed for those purposes or legal obligations. Apple and Google keep their own store records. Offline copies or device backups may need separate removal. Delete Account
Depending on applicable law, you may have rights to access, correct, delete or obtain a copy of your data, object to or restrict certain uses, withdraw consent, or complain to a privacy authority. Contact support@altheagroup.net to exercise an applicable right. We may verify your identity or ownership before acting.
Children’s privacy and security
Donut Circuit is a puzzle game with optional sign-in, ads and purchases. If you are a parent or guardian and believe a child’s information was processed without a permission required by law, contact us so we can review it and take appropriate action. We use account access controls, app integrity checks and transaction verification to help protect data and prevent misuse.
