Privacy Policy
Go! Hamster: World Tour · Updated 3 November 2026
This policy covers version 2.0 and later of Go! Hamster: World Tour, including World Tour, Classic and Endless modes on supported mobile and TV platforms. Features may differ by platform and release.
Who operates the game
Developer: Ivan Derezin. For privacy questions, access or deletion requests, contact ivderezin@gmail.com. Please do not send passwords or account authentication codes.
Local game data
The game stores progress, scores, unlocked costumes, daily tasks, settings and consent choices on your device. Normal gameplay does not require an account with us. Optional cloud synchronization is provided through your platform account, as described below; we do not operate a separate account or cloud-save server. Your operating system may include local app data in its backups according to your device settings. Clearing app data removes local progress and preferences; uninstalling may not remove an operating-system backup.
Optional diagnostics
On supported mobile platforms, Firebase Analytics and Crashlytics collect usage and crash diagnostics only after you enable them. These can include installation identifiers, device and operating-system information, app version, gameplay events (such as level, mode, score, outcome and costume), crash stack traces and diagnostic context. We do not add your name, email or account ID to gameplay analytics. Firebase advertising personalization and advertising-ID collection are disabled in our configuration. Diagnostics are disabled on Apple TV.
You can turn diagnostics off in Settings. This stops future collection and clears queued data managed by the app; it does not automatically delete data already received by the provider. Provider processing and retention are described in Firebase Privacy and Security and Google's Privacy Policy. We use diagnostics to understand gameplay and fix errors.
Android advertising and age choices
Android phones, tablets and Android TV can show ads through Yandex Mobile Ads. There are no ads on iOS or tvOS. Before enabling Android ads we ask for an age category, not a birth date. If you select under 18 or prefer not to say, the advertising SDK is not initialized and no advertising requests are made. We do not send this age choice as a gameplay analytics event.
Players who confirm they are 18 or older choose whether to allow personalized advertising. The choice is stored locally and can be changed in Settings. With permission, Yandex may process advertising identifiers, IP address, device/app information and ad interactions for advertising, measurement and fraud prevention. Declining personalization passes a negative consent signal and restrictive data-collection setting to the SDK; ads still involve network requests and technical data. Precise location tracking and additional app-ad analytics reporting are disabled by the game.
Yandex processes advertising data under its Privacy Policy. Its services may process data outside your country. Changing consent stops future personalized requests but does not retrospectively delete data already processed. You can also use Android's advertising privacy controls.
Interstitial ads may appear between completed attempts, subject to frequency limits. An optional rewarded video offers one continuation of the current level after a loss, preserving completed progress. The reward is granted only when the ad provider confirms completion. Videos do not award coins. Ads are never required to start the game or use the ordinary restart action.
Children and families
The game is intended for a mixed-age audience. We do not enable Android advertising for under-18 or unknown-age users, and we do not request their consent to advertising personalization. Parents and guardians can keep optional diagnostics disabled and contact us about privacy concerns. We do not intentionally request children's names, email addresses or exact birth dates through the game.
Platform game services
Where available and enabled, Apple Game Center or Google Play Games handle platform sign-in, achievements and leaderboards when you use those features. Scores and achievement progress are submitted to the relevant platform; your platform nickname, avatar and ranking may be visible to other players according to that platform’s privacy settings. These services process platform account identifiers and achievement progress under Apple's Privacy Policy or Google's Privacy Policy. We do not receive your account password. Game-service sign-in and cloud synchronization are separate features.
Optional cloud saves
You can enable synchronization in the game settings. On iPhone, iPad and Apple TV, saves use the private database in your Apple iCloud account through CloudKit. On Android and Android TV, saves use Google Play Games Saved Games. Saves are synchronized within one ecosystem, not between Apple and Android.
A save contains game progress, level results, scores and times, costumes, in-game currency and upgrades, daily tasks, the current run, and save revision and device metadata needed to synchronize changes. Permissions, age and advertising choices, diagnostics consent, language, sound and control settings remain local and are not included in cloud saves. Platform account identifiers are used locally to detect account changes; the game does not receive your account password.
After you enable synchronization, the app may upload changes and check for newer saves automatically. Conflicting currency or active-run changes require your choice. Disabling synchronization stops future synchronization but does not erase the existing provider-held save. Uninstalling or clearing local data does not necessarily delete a cloud save, platform scores or achievements. Manage retained data through the relevant Apple or Google account controls; contact us for assistance with requests concerning data controlled by us. Provider retention, processing locations and deletion controls follow the Apple and Google privacy policies linked above.
Notifications and support
Optional reminders are scheduled locally after your permission. They do not require an address book or a developer push-messaging server. You can disable them in the game or system settings. If you email support, we receive your email address and the information you choose to include; we use it to answer your request.
Your choices and rights
You can change diagnostics and adult advertising-personalization preferences in Settings, manage notifications in system settings, and remove locally stored data using your device's app-data controls. Depending on your location, you may have rights to access, correct, delete or restrict processing of personal data, withdraw consent, or complain to your local data-protection authority. Contact us for requests concerning data we control. Platform and advertising providers provide their own account and privacy tools. We may need enough information to locate relevant records; we cannot reliably link anonymous gameplay events to an email address.
Security, retention and updates
We limit data use to providing the game, optional diagnostics, advertising where enabled, and support. Local data remains until removed or overwritten; provider-held data follows the provider's retention and deletion controls. Support correspondence is kept as needed to resolve the request and meet applicable obligations. No storage or transmission method is completely secure. We may update this policy when the game or its services change and will update the date above.
