常见问题Frequently asked
需要注册账号吗？Do I need an account?
不需要。装上就能用，没有注册、没有登录、不用邮箱。 No. Install it and start using it — no sign-up, no login, no email required.
我的数据存在哪里？会上传吗？Where is my data stored? Is it uploaded?
全部存在你自己的设备上。物品、照片、分类都不会自动上传。唯一的例外是你主动使用小票识别时，那一张照片会发送给 AI 服务读取文字。详见 隐私政策。 All on your own device. Items, photos and categories are never uploaded automatically. The one exception is receipt scanning: that single photo is sent to an AI service to read its text. See the privacy policy.
换手机了，怎么把数据带过去？I got a new phone — how do I move my data?
在旧手机上打开「设置 → 备份」，导出备份文件，通过 AirDrop 或 iCloud Drive 传到新手机，然后在新手机上打开「设置 → 备份 → 导入」选择该文件。照片会一起恢复。 On the old phone go to Settings → Backup and export a backup file. Send it to the new phone via AirDrop or iCloud Drive, then on the new phone choose Settings → Backup → Import and pick that file. Photos come across too.
小票识别不准怎么办？The receipt scan got things wrong. What now?
识别结果在导入前都可以逐项修改，所以不用担心错了会直接进库。提高准确率的几个办法：把小票铺平、光线充足、让文字尽量占满画面、避免反光和折痕。热敏纸小票褪色后识别率会明显下降。 Every field is editable before import, so nothing wrong gets saved without your say-so. To improve accuracy: flatten the receipt, use good light, fill the frame with the text, and avoid glare and creases. Faded thermal-paper receipts are noticeably harder to read.
支持哪些系统版本和设备？Which iOS versions and devices are supported?
需要 iOS 17 或更高版本。拍照相关功能需要真机的摄像头。 iOS 17 or later. Camera-based features need a device with a working camera.
能记录过期提醒和补货提醒吗？Can it remind me about expiry and restocking?
可以设置过期日期，临期物品会在列表中自动置顶。系统通知提醒需要你在首次使用时允许通知权限，通知全部在本地生成，不经过服务器。 Yes — set an expiry date and items nearing it rise to the top of the list automatically. Push reminders require notification permission on first use; all notifications are generated locally, with no server involved.
是免费的吗？有内购吗？Is it free? Any in-app purchases?
免费，没有内购，没有广告，没有订阅。 Free. No in-app purchases, no ads, no subscriptions.
怎么彻底删除我的所有数据？How do I delete all my data?
从设备上卸载 ItemMaster 即可，本地数据库和所有照片会一并移除。因为我们这边没有你的数据副本，所以不需要向任何人提交删除申请。 Delete ItemMaster from your device — the local database and every stored photo go with it. Since we hold no copy of your data, there's no deletion request to submit to anyone.
