FOB.Games / Privacy
Policy applicable to Gravity Chain for Android. Last updated: 12 August 2026.
V1 TRANSPARENCY
This policy applies to Gravity Chain for Android, published under package name com.fobgames.gravitychain. It describes processing connected with the V1 release using the services listed below.
FOB.Games publishes and operates Gravity Chain. The official contact for privacy or data questions is fobgames.contact@gmail.com.
Gravity Chain creates no FOB.Games player account, public profile or social feature for publishing content.
Progress, records, statistics, XP, Cosmic Shards, challenges, cosmetics and settings are stored locally on the device. FOB.Games operates no player account or cloud save for this data.
The optional import feature only reads the JSON file selected by the user, validates it and incorporates it into the local save. Its contents are not sent to a FOB.Games server.
Android automatic backup is disabled. Clearing application storage or uninstalling may permanently remove local progress. Core gameplay works offline, but ads, consent, prices and purchases require a connection to Google services.
Gravity Chain uses Google Mobile Ads (AdMob) and the User Messaging Platform (UMP). Depending on region and user choices, Google may serve personalised, non-personalised, limited or technical ads.
Google Mobile Ads may collect or share the IP address, general location inferred from it, interactions with the app and ads, diagnostic information, and device or account identifiers including the Android advertising ID and App Set ID where available. Actual processing depends on device, region, configuration and privacy choices.
Rewarded ads are optional and started by the player. Interstitial ads are restricted to natural breaks between runs, after at least five completed runs and ten minutes in the session, with no more than two per session. Gravity Chain uses no banner and no mediation network.
UMP checks consent status at launch where required. Privacy choices can be reopened from the game Settings. Receiving an advertising reward requires completing the corresponding ad online.
Gravity Chain uses Google Play Billing to offer non-consumable cosmetic purchases and restore products already owned. Google Play handles checkout and payment methods.
The app may receive the product identifier, localised price, purchase state, acknowledgement state and purchase token to unlock or restore content. These elements are processed inside the app and are not sent to a FOB.Games server.
FOB.Games does not receive full payment-card numbers. Premium products are linked to the Google Play account used for purchase and can be restored through that account. Free progression and equipped cosmetics nevertheless remain local to the device.
When you contact FOB.Games, we receive the information you choose to send, such as your email address, message, attachments and, for a purchase request, a Google Play order number.
This information is used only to reply, diagnose the issue, provide reasonable follow-up and meet applicable obligations. Never send passwords, full payment-card numbers, banking details, security codes or purchase tokens.
Processing is used to provide the game and settings, grant requested rewards, collect privacy choices, process and restore purchases, measure and secure services, prevent fraud and answer support requests.
Depending on the processing and applicable law, the legal basis may be consent, performance of a purchase or requested service, a legal obligation, or legitimate interest in securing and maintaining the service. FOB.Games does not sell personal data.
Potential recipients are FOB.Games for support, and Google for Google Mobile Ads, UMP, Google Play Billing, Google Play and Gmail. Android and the device manufacturer may also process information under their own policies.
Google may process data in multiple countries and applies the safeguards described in its privacy policy. Retention periods for Google services follow their rules and account or device settings.
Local data remains on the device until it is replaced, application storage is cleared or the app is uninstalled. Support messages are kept only as long as needed to handle and reasonably follow up the request and meet applicable obligations.
You can manage advertising choices in Gravity Chain Settings where UMP requires it, manage the advertising ID in Android and review purchases in Google Play. To erase local data, use Android application settings or uninstall the app.
Depending on your country, you may request access, correction, deletion, restriction, portability or objection, and withdraw consent without affecting prior processing. Email fobgames.contact@gmail.com without unnecessary sensitive information. You may also complain to the competent supervisory authority.
Gravity Chain provides no account creation or public content posting. Minors should use the app with permission or supervision from a legal guardian where applicable law requires it.
Communications with Google are protected in transit through those services’ safeguards. Local data remains subject to device security. No system can guarantee absolute security.
This policy may change if features, providers or legal requirements change. Its date and content will then be updated on this page.
