Privacy Policy
AndySun operates GeminiDefense for iOS and iPadOS. This policy explains how information is handled when you play the game, make or restore purchases, or contact us. Contact: andysun1024@163.com. Last updated: September 24, 2026.
1. Playing without an account
You can play without registering a game account or signing in with Apple. The game creates a random guest identifier (UUID) to support purchase association and player support. It is not your Apple Account, advertising identifier, or a hardware identifier. The PLAYER panel displays this ID. COPY ID writes it to your clipboard only when you choose that action; it does not send it to us. The game does not read your clipboard.
2. Information stored on your device
The game stores a local profile containing guest and commander identifiers, a commander display name, profile timestamps, language and audio preferences, selected planet and mode, campaign progress, tutorial completion, tower upgrades, research stars, reward history, best runs, victory and defeat counts, lifetime score and gold totals, and cached purchase-unlock status. These records support gameplay, settings, reward accounting, and access to purchased content. The game does not upload your save to a developer-operated server or provide its own cloud-save service. Restoring purchases does not restore game progress. Device backups managed by the operating system are separate from the game's save system.
3. Purchases and Apple
Optional non-consumable purchases are processed by Apple's App Store through StoreKit. When you initiate a purchase, the game supplies the random guest UUID to Apple as an appAccountToken to associate the transaction with a guest profile. StoreKit supplies product information, localized prices, purchase results, and verified transaction and entitlement information so the game can grant or restore the correct unlocks. The game checks Apple's verified transaction results on the device; this version does not send receipts to a developer-operated verification server.
RESTORE PURCHASES asks Apple to synchronize your eligible purchases and may require App Store authentication. Use the same Apple Account that made the purchase. We do not receive your payment-card number or Apple Account password. Apple processes purchase records under its own terms and privacy policy: https://www.apple.com/legal/privacy/en-ww/. Apple may separately make sales reports and platform diagnostics available to developers under its platform rules and your applicable sharing settings.
4. Advertising, tracking, and device permissions
This version contains no advertising SDK or third-party behavioral analytics SDK. We do not sell personal information or share it for cross-app targeted advertising. The game does not request access to your contacts, camera, microphone, photo library, or precise location. It does not use an advertising identifier to track you across apps or websites. Operating-system or App Store processing is governed separately by Apple's settings and policy.
5. When you contact support
If you email andysun1024@163.com, we receive your email address, message, and any information you voluntarily include, such as a guest ID, device model, operating-system version, screenshots, or purchase issue details. We use these only to answer your request, troubleshoot, protect against abuse, and meet applicable legal obligations. Please do not send passwords, full payment-card details, or unnecessary personal information. Our email service provider processes messages to deliver and store support correspondence. We do not use support messages for advertising.
6. Sharing and international processing
The game's purchase flow communicates with Apple. Support emails are handled through our email service provider. Information may also be disclosed when required by applicable law or where necessary to protect legal rights and security. We do not upload your local gameplay profile to an advertising network or a developer cloud database. Apple and email services may process information outside your country, subject to their service arrangements and applicable data-protection requirements.
7. Retention and deletion
Local game records remain on your device until removed. On iOS or iPadOS, deleting the app (rather than offloading it) removes the app's local container; any separate device backups must be managed through your device or Apple settings. Deleting local progress is irreversible unless you have a usable backup.
On supported Apple devices, the guest UUID is also stored in the device Keychain to keep the identifier stable. Keychain data may survive uninstalling or reinstalling the app. The current game does not include a control to delete or reset that Keychain entry, and we cannot erase it remotely. Contact us for guidance; do not assume that uninstalling erases every identifier.
Deleting the app does not cancel a purchase or delete Apple's transaction records. Eligible non-consumable purchases can be restored through Apple. We retain support correspondence only as long as necessary to resolve requests, address disputes, maintain security, or meet legal obligations, and delete or anonymize it when no longer needed. You may request earlier deletion, subject to applicable exceptions.
8. Your choices and privacy rights
You can play without registering, choose not to buy optional content, change preferences in Settings, and decide what to send in a support request. Depending on your location and applicable law, you may have rights to request access, correction, deletion, restriction, portability, or objection concerning personal information we hold, to withdraw consent where processing relies on consent, and to complain to a competent data-protection authority. Contact andysun1024@163.com to exercise these rights. We may ask for information reasonably necessary to verify your request, but never your Apple password or full payment-card details. We cannot access, recover, or remotely edit a save stored only on your device. Requests about Apple's own records should also be directed to Apple.
Where a legal basis is required, processing to provide purchases and requested support is based on providing the requested service; limited security and support administration may rely on legitimate interests; required record handling may rely on legal obligations. Where consent is required, it must be obtained separately. This policy is a notice, not a substitute for that consent.
9. Children and families
The game does not ask players to enter their date of birth, real name, postal address, or contact details to play. It has no in-game chat, public user profiles, targeted advertising, or behavioral advertising SDK. Local gameplay records and the guest purchase token are used for the functions described above, not advertising profiles. Parents or guardians should supervise purchases and contact support on a child's behalf. We do not knowingly solicit personal information from children through support. If you believe a child has sent us personal information that should not be retained, contact us so we can investigate and delete it where appropriate. A store age rating or purchase authorization does not itself constitute consent to collect a child's personal information.
10. Security
We limit the information handled by the game, use on-device storage and Apple's Keychain for the guest identifier on supported devices, and use StoreKit's verified transaction results for purchase validation. No storage or transmission method is completely secure. Protect access to your device and Apple Account, and avoid sharing your guest ID publicly when it is not needed.
11. Reading this policy on the website
The in-game policy is bundled with the app and can be read offline without opening a website. If you visit our website, your browser necessarily sends connection information such as an IP address and browser details to the web host; server or security logs may be generated. This policy page itself does not embed advertising, tracking pixels, third-party analytics, or third-party fonts and does not set cookies. These website requests are distinct from local gameplay records. Contact us with questions about website access logs.
12. Updates and contact
We will revise this policy if relevant features or data practices change and update the date above. Material changes will be communicated as required by applicable law, and any required consent will be obtained before the new processing. Developer and operator: AndySun.
