1. Information handled by the app
Retro Club Grand Prix is an offline game without registration. The app does not collect personal information or transmit it to developer servers. It contains no advertising, analytics or tracking SDKs.
2. Retro Pass (in-app purchase)
The app offers one optional one-time purchase, the Retro Pass, which stays unlocked once bought. Payment is handled by the App Store; the developer never receives or stores card numbers or other payment details. To confirm and restore the purchase, the app checks your App Store purchase history for this item and stores the purchase state on your device. The purchase-state file is signed with device information so it only opens on this device; that value is never sent off the device. Apple's policies apply to payments and refunds.
3. Local game data
Language and control settings, championship progress, race records, stamps, time attack ghosts and Retro Pass ownership are stored in the app's private storage on your device. The developer cannot access them. The game has no account-based sync or built-in cloud saving. iOS and iPadOS device backups and device transfers may include game data, depending on Apple services and your device settings. The developer cannot access these backups. Clearing app storage or uninstalling deletes local game data. Progress recovery after reinstalling or changing devices is not guaranteed. The Retro Pass can be restored with Restore in the app while signed in to the same Apple Account.
4. Sharing, external links and this website
The app does not collect personal information to share or sell. Opening the policy launches your default browser. This policy is hosted on Cloudflare Pages. The hosting provider may process IP addresses, request times and browser information for delivery, security and abuse prevention. Email and hosting services may process information outside your country of residence. We do not add advertising or separate behavioral analytics tags to this policy page. External services apply their own privacy policies.
5. Support correspondence
If you email us, we use your reply address, message and voluntarily provided attachments to respond and troubleshoot. Information no longer needed for this purpose is deleted, except where retention is required by law. Do not send sensitive or unnecessary personal information. To request access, correction, deletion or restriction of support information, contact [email protected]. We may request the minimum information needed to verify a request and explain any legal retention requirement.
6. Children
The app does not collect personal information from users of any age. A parent or guardian who believes a child's personal information was supplied in a support request may contact us to request deletion.
7. Changes
We will update this policy and effective date if features or data practices change and provide notices or consent where required. The current policy is available on this website.
