Email support@lumiora.ai. Include your device, iOS version, the app version shown in Settings → About, and what happened. Screenshots and an exported save code are optional; never send passwords or payment-card details.
Use the Apple ID that bought the full game. Open a locked chapter, then choose Restore purchases. A restored purchase unlocks paid content; it does not transfer gameplay progress. If Apple charged you but the unlock is missing, contact us with the app version and approximate purchase date. Apple handles billing and refund requests.
Before changing devices or removing the app, export your save code in Settings → Save data and keep it somewhere safe. Import that code on the other device. Device backups do not provide live cross-device save synchronization.
Check available device storage and try exporting again. Choose the destination in the system share sheet. Cancelling the sheet does not save a copy. If exporting still fails, email us the app version and describe the image or replay you tried to share.
请发邮件至 support@lumiora.ai，并提供设备、iOS 版本、「设置 → 关于」中的 App 版本，以及遇到的问题。截图和导出的存档码可选；请勿发送密码或银行卡资料。
请使用购买完整版时的 Apple ID。点开一个锁定章节，选择「恢复购买」。恢复购买仅解锁付费内容，不转移游戏进度。如果已扣费但未解锁，请联系我们并提供 App 版本与大致购买日期。账单和退款由 Apple 处理。
更换设备或删除 App 前，请在「设置 → 存档」导出并妥善保存存档码，在另一台设备导入。设备备份不提供多设备实时同步。
检查设备剩余存储空间后再次导出，在系统分享面板中选择保存位置。取消分享不会保存副本。如果仍然失败，请联系我们，附上 App 版本并描述要分享的图片或录像。
