GYUFORGE / RUMBLORB
Privacy Policy
GYUFORGE processes the information below to provide RUMBLORB accounts, saves, purchases and advertising.
Effective October 12, 2026
1. Account and game data
Creating a server account stores a random account identifier, creation time and authentication session information. Linking Google stores the Google account identifier and display name. Progress backups store stage records, game settings, earned currency and items, upgrade details and custom marble configurations. We use these to identify your account, restore progress and provide game features. Game saves and authentication information are also stored on your device.
2. Purchases and support
For in-app purchases, we process product IDs, order and purchase verification information, hashed purchase tokens, grant/consumption/refund records and account associations. Tokens needed for re-verification are stored encrypted. This supports purchase verification, delivery, duplicate prevention and refunds. Google Play processes payment methods and card numbers. When you contact us by email, we process the sender address, message and materials you provide.
3. Advertising
Google’s AdMob SDK may collect and share IP addresses, which can indicate approximate location; app and ad interactions; app/SDK diagnostics; and device identifiers such as advertising and app set IDs. Google uses these for advertising, measurement and fraud prevention. Android settings allow you to reset or delete the advertising ID. Where consent is required, follow the privacy choices shown in the app. See the Google Privacy Policy and AdMob data disclosure.
4. Providers and international processing
Cloudflare provides the account API, database, policy-site hosting and security. Google provides sign-in, Google Play payments and AdMob ads. Network requests include IP addresses and information needed for communications. Providers may process this information through their global infrastructure. See the Cloudflare Privacy Policy and Google Privacy Policy for their practices and contacts.
5. Retention and deletion
We retain account and game data as needed to provide the service and process deletion requests after identity verification. Where Korean e-commerce retention duties apply, contract/cancellation/payment/supply records may be retained for five years and consumer complaint/dispute records for three years. Minimum records needed for legal duties or an unresolved dispute are kept for those purposes and reviewed for erasure when the reason ends. Backups may contain earlier records; deletion handling includes checking that a restore does not reactivate the deleted account. Information held independently by providers such as Google is subject to their own policies.
6. Your rights
Request access, correction, deletion or restriction of processing at contact@gyuforge.com. The account deletion page explains the process and scope. We may request the minimum information needed to verify you or your legal representative. Parents and guardians can use the same address for children’s privacy requests.
7. Protection and contact
Account APIs use HTTPS and server sessions are stored as hashes. Authorized operators handle privacy requests. Privacy contact: GYUFORGE · contact@gyuforge.com. We update this page and its effective date when the policy changes.
