卡牌居中检查 隐私政策
「卡牌居中检查」（以下简称“本应用”）由本政策末尾列明的开发者（以下简称“我们”）开发和运营。我们依据《中华人民共和国个人信息保护法》等法律法规制定本政策，请您在使用前仔细阅读。
一、我们收集的个人信息
本应用不收集任何个人信息：不需要注册或登录；不收集设备标识符（如 IMEI、OAID、Android ID、MAC 地址）；不收集位置、通讯录、通话记录、短信、已安装应用列表等信息；不读取剪贴板；不进行数据统计、行为分析或广告追踪。本应用不与任何服务器通信。
二、照片的使用方式
您通过系统自带的照片选择器主动选择一张照片，本应用只能读取您选中的这一张，无法浏览您的相册。
照片只在设备内存中用于显示、测量和自动识别卡牌边框，不会上传到任何服务器，也不会发送给任何第三方；自动识别完全在设备上计算完成。
部分系统在选图时会把照片复制一份到本应用的临时目录，本应用读取后立即删除这份副本，不会保存您的照片。
三、测量记录
只有在您点击“保存”时，本应用才会保存一条测量记录，内容仅包括：左右和上下比例、参考等级、保存时间，以及您自愿填写的备注（如卡牌名称）。
测量记录不包含照片，也不包含任何设备信息，只保存在本应用在您设备上的私有存储中，不会上传。您可以在“记录”页随时删除单条记录或全部清空；卸载本应用后，记录随之删除。
四、结果图
结果图由本应用在设备上生成，包含卡牌图片、参考线、比例和参考等级。只有在您点击“保存图片”时才会保存：安卓系统直接保存到相册的“CardCentering”文件夹（Android 10 及以上，无需任何权限）；鸿蒙系统由系统弹出保存确认框，经您确认后保存到图库。本应用不会读取您相册中的其他照片，也不会自动分享结果图。
五、设备权限
本应用不申请任何设备权限，包括网络、存储、相机、相册读取、位置、电话等权限。本应用没有网络权限，无法联网。
六、第三方 SDK
本应用未接入任何第三方 SDK，包括广告、统计、推送、登录、支付、分享和崩溃收集类 SDK。
七、本机保存的信息
除您主动保存的测量记录外，本应用只在本机保存一项设置：您是否已同意本政策，用于避免每次打开都弹出提示。这项设置不含个人信息，卸载本应用即被删除。
八、自启动和关联启动
本应用没有自启动行为，也没有关联启动行为，只在您主动打开时运行，不在后台常驻。
九、信息的共享、转让和公开披露
由于本应用不收集任何个人信息，我们不会与任何公司、组织或个人共享、转让或公开披露您的个人信息。
十、您的权利
我们不持有您的任何个人信息，因此不存在需要向我们申请查阅、更正、删除的个人信息，也没有需要注销的账号。您可以在“记录”页自行删除测量记录，或随时卸载本应用。如果您认为我们的行为损害了您的合法权益，可以联系我们，也可以向网信、工信等监管部门投诉或举报。
十一、未成年人保护
本应用不收集任何人的个人信息，包括未满 14 周岁的未成年人。若您是未成年人，建议在监护人的陪同下阅读本政策并使用本应用。
十二、免责说明
本应用给出的参考等级依据公开的居中标准计算，结果仅供参考，不代表实际评级。本应用与任何卡牌评级机构均无关联。
十三、本政策的更新
如果本应用的功能变化涉及个人信息的处理方式，我们会更新本政策，并在应用内以弹窗方式提示您。

Card Centering Check — Privacy Policy
Card Centering Check ("the app") is developed and operated by the developer named at the end of this policy ("we"). Please read this policy before using the app.
1. Personal information we collect
The app collects no personal information. There is no sign-up or login. It does not collect device identifiers (such as IMEI, OAID, Android ID or MAC address), location, contacts, call logs, messages or the list of installed apps. It does not read the clipboard, does no analytics, tracking or advertising, and does not communicate with any server.
2. How your photo is used
You choose one photo with the system photo picker; the app can read only that photo and cannot browse your library.
The photo is used only in memory on your device for display, measuring and edge detection. It is never uploaded or sent to anyone; edge detection runs entirely on the device.
Some systems copy the chosen photo into the app's temporary folder; the app deletes that copy right after reading it and never keeps your photo.
3. Saved measurements
Only when you tap "Save" does the app store a measurement: the left/right and top/bottom ratios, the reference grade, the time and an optional note you type (such as the card name).
Records contain no photos or device information, stay in the app's private storage on your device and are never uploaded. You can delete one record or clear all of them in Records at any time; they are removed when you uninstall the app.
4. Result image
The result image is created on your device and shows the card, guide lines, ratios and reference grade. It is saved only when you tap "Save image": on Android it goes straight to the "CardCentering" album (Android 10 and later, no permission needed); on HarmonyOS the system asks you to confirm before saving it to the gallery. The app never reads other photos in your library and never shares the image on its own.
5. Device permissions
The app requests no device permissions, including network, storage, camera, photos, location and phone. Without network permission it cannot connect to the internet.
6. Third-party SDKs
The app contains no third-party SDKs, including advertising, analytics, push, login, payment, sharing and crash reporting SDKs.
7. Information kept on your device
Besides the measurements you choose to save, the app keeps one setting on your device: whether you have agreed to this policy, so the notice is not shown every time. It contains no personal information and is removed when you uninstall the app.
8. Auto-start and chained start
The app does not start by itself and does not start or get started by other apps. It runs only when you open it and does not stay in the background.
9. Sharing and disclosure
As the app collects no personal information, we do not share, transfer or disclose any personal information.
10. Your rights
We hold no personal information about you, so there is nothing to request access to, correct or delete, and no account to close. You can delete your records in the app or uninstall it at any time. If you believe your rights have been harmed, you can contact us or complain to the relevant authorities.
11. Children
The app collects no personal information from anyone, including children under 14. Minors should read this policy and use the app with a parent or guardian.
12. Disclaimer
The reference grade is calculated from published centering standards and is for reference only; it is not an actual grade. The app is not affiliated with any card grading company.
13. Changes to this policy
If a change to the app affects how personal information is handled, we will update this policy and tell you in the app with a notice.
14. Contact us
If you have any questions or complaints about this policy, contact us and we will reply within 15 working days:
