Moji Blast! ("we", "our", "the app") is developed by SparkArk Studio. We respect your privacy. This policy explains what data is collected, who collects it, how it is used, and what rights you have. It applies to the Moji Blast! mobile app on iOS and Android.
We never ask you for your real name, email address, phone number, or location, and the app has no registration or sign-in. Your game data (level progress, settings, coins, lives, boosters, and your local best score) is stored on your device using the operating system's standard preferences storage (SharedPreferences). The one exception is the online leaderboard, which publishes a small amount of data to a server. It is described in the next section. The data described in the remaining sections is collected by third-party SDKs built into the app (Google), not by us directly. We can see it only as aggregated, pseudonymous statistics.
The Classic mode leaderboard is online, so taking part means publishing data to a server. This is the only feature that stores data about you outside your device. When you set a Classic best score, the app signs in anonymously to Google Firebase Authentication. Anonymous sign-in creates a random identifier for your installation; it involves no email, password, or account of any kind, and it is not linked to your Google account or to you personally. Stored against that identifier in Google Cloud Firestore are: your best Classic score, the display name you chose, your selected avatar, your highest Adventure level, and the time of the last update. Your display name and avatar are visible to every other player in the leaderboard, so please do not use your real name or any other personal detail. Names are filtered before publication, and names that are offensive, that contain contact details, or that impersonate us are refused. If you never set a Classic score, nothing is ever written and no identifier is created. To have your leaderboard entry deleted, email us at sparkarkstudiosocial@gmail.com and we will remove it.
The app includes Google Analytics for Firebase and Firebase Crashlytics, which help us understand how the game is played and fix bugs. • Analytics collects a randomly generated app-instance identifier, device model, operating system version, language, approximate country/region (derived from IP address, which Google truncates and does not store), and gameplay events such as level starts and completions, booster use, ad views, and purchase confirmations. • Crashlytics collects, when the app crashes or hits an error, a crash report containing a Crashlytics installation identifier, device state (model, OS version, memory, whether the device is rooted/jailbroken) and a stack trace. This data is pseudonymous — it is not linked to your name and we do not attempt to identify individual players from it. We do not sell it. Analytics data is retained for up to 14 months and crash reports for up to 90 days, after which Google deletes them automatically.
The app displays ads served by Google AdMob. AdMob may collect device identifiers (e.g. IDFA on iOS, Android Advertising ID) and use them to show personalized ads, subject to your consent. • On iOS you will be shown the standard App Tracking Transparency (ATT) prompt before any ad is shown. Choosing "Ask App Not to Track" limits ads to non-personalized only. • In the EEA / UK you will see a Google-managed consent form (UMP) before ads are loaded. You can reopen that form and change or withdraw your consent at any time from Settings → Privacy → Choices inside the app. • In supported US states no form is shown up front, because those laws work on an opt-out basis. You can open your "Do Not Sell or Share My Personal Information" options at any time from Settings → Privacy → Choices inside the app.
The app offers optional in-app purchases (for example "No Ads" and coin packs). Payments are processed entirely by Apple's App Store or Google Play — we never see or store your payment card, billing address, or store account details. The platform tells the app only whether a purchase succeeded, and that confirmation (product identifier, price, currency) is recorded as an analytics event.
The third parties whose SDKs are embedded in the app, and what each may collect: • Google AdMob — advertising identifier (IDFA / GAID), IP address, device type and OS version, ad interaction events. See the Ad Partners page. • Google Analytics for Firebase — app-instance ID, device and OS information, approximate country, gameplay events. • Firebase Crashlytics — crash reports, installation ID, device state. • Firebase Authentication — an anonymous user identifier, created only if you set a Classic best score. No email or password is involved. • Google Cloud Firestore — your leaderboard row: best score, display name, avatar, highest Adventure level. See the Online Leaderboard section. • Apple App Store / Google Play Billing — purchase and subscription data, handled under Apple's and Google's own policies. All of the above are governed by Google's Privacy Policy (policies.google.com/privacy) and Apple's Privacy Policy (apple.com/legal/privacy). We require every third party with whom app data is shared to provide protection for that data at least equivalent to this policy.
Moji Blast! is not directed at children under the age of 13 (or 16 in the EEA / UK), and we do not knowingly collect personal information from children. The app is not published under Google Play's Designed for Families programme and is not rated for young children. If you are a parent or guardian and believe a child has provided personal information through the app, please contact us at sparkarkstudiosocial@gmail.com and we will delete it. Parents can also disable in-app purchases through the parental controls of the App Store or Google Play.
Depending on where you live (for example under the GDPR in the EEA/UK, or the CCPA/CPRA in California) you may have the right to access, correct, delete, or restrict the processing of personal data about you, and to lodge a complaint with your local data protection authority. In practice: • Local game data — reset it at any time via your device's app settings ("Clear Data" / "Reset app"), or by uninstalling the app. • Advertising — deny the ATT prompt (iOS), enable "Opt out of Ads Personalisation" (Android), reopen the EEA/UK consent form from Settings → Privacy → Choices in the app, or use "Do Not Sell or Share My Personal Information" from the same place if you live in a supported US state. • Leaderboard entry — email us and we will delete your row (score, display name, avatar, level) from the leaderboard. You can also change your display name at any time from the Profile screen in the app. • Analytics & crash reporting — email us and we will delete the data associated with your app instance from Firebase. Step-by-step instructions, and exactly what is deleted or kept, are on our Data Deletion page. We never sell personal information for money. Personalised advertising through AdMob may nonetheless count as a "sale" or as "sharing" for cross-context behavioural advertising under California and other US state privacy laws. We share data for no purpose other than the advertising described above, and you can opt out at any time from Settings → Privacy → Choices in the app. To exercise any right, contact sparkarkstudiosocial@gmail.com; we respond within 30 days.
The third-party services described above are operated by Google LLC and Apple Inc. and may process data on servers located outside your country, including in the United States. Those transfers are made under the safeguards those companies publish in their own privacy policies (including the EU Standard Contractual Clauses).
We may update this Privacy Policy from time to time. The current version is always accessible inside the app (Settings → Privacy) and at this URL, and carries the effective date shown at the top. Material changes will be announced in the app. Continued use of the app after changes are published constitutes acceptance of the updated policy.
For any privacy questions, data requests, or concerns, contact SparkArk Studio at sparkarkstudiosocial@gmail.com. We aim to reply within 5 business days and, for formal data requests, within 30 days.
