一、我们如何收集和使用您的个人信息
我们仅在为您提供应用功能时按最小必要范围收集个人信息。以下为本应用实际可能收集或处理的信息类型与用途：
1. NFC 标签与设备标识
当您在应用内使用“读取/写入 NFC”功能时，应用会读取或写入 NFC 标签中的文本/JSON 数据及标签 ID，用于设备配对、导入设备信息或写入配置。
2. 相机与扫码
当您使用扫码或拍照功能时，应用将使用相机拍摄图像以便解析二维码或上传图片。
3. 相册/媒体访问
当您从相册选择图片或上传图片时，应用会读取相册中您选择的图片文件（仅在您明确选择时）。
4. 外部存储（兼容旧设备）
为兼容某些旧版 Android 系统，应用可能在需要时请求读取或写入外部存储（仅在您明确保存/导入文件时使用）。
5. 剪贴板
应用提供“复制到剪贴板”功能，只有在您点击复制时才会将内容写入剪贴板；应用不会在后台读取用户剪贴板内容。
6. 网络与上传
应用会通过网络上传图片、设备信息或 NFC 读取结果以提供服务（如设备绑定或云端功能），这些传输可能包含设备 IP 等传输元数据。
- IMEI / IMSI / ICCID / Android ID / OAID
- 通讯录（联系人）、短信、通话记录
- GPS 定位（未请求位置权限）
- 麦克风录音（未请求录音权限）
- 生物识别信息（指纹/面容）
二、我们如何使用 Cookie 和同类技术
我们可能使用 Cookie、HTTP 缓存、本地存储（如 SharedPreferences、应用缓存、get_storage 等）以及其他同类技术来：
- 保持用户会话、记住偏好设置；
- 帮助诊断和修复问题；
- 辅助判断图片是否通过网络下载（HTTP 请求追踪用于改善用户体验）。
如果在未来引入第三方 SDK（如用于分析或广告）的 Cookie/跟踪技术，我们会在此处及应用中公示并提供相应的开关与说明。
三、我们如何共享、转让、公开披露用户的个人信息
我们不会向任何无关第三方出售或出租个人信息。仅在以下情况下可能共享信息：
- 您明确授权并同意的场景；
- 为实现您选择的功能而必需的服务提供商（如图片存储或第三方分析服务），我们会与其签订数据处理协议并限制其仅为实现服务目的使用数据；
- 法律法规或政府监管机构依法要求披露时。
四、我们如何存储收集的用户信息
我们会在满足业务需要和符合法律法规的前提下，采用合理的技术和管理措施存储用户数据。存储方式包括：
- 本地存储：缓存、数据库或应用专用存储（仅存储必要信息）；
- 服务器存储：用于同步或备份的情况下，数据会传输至我们的服务器并受服务器安全策略保护。
我们会在数据不再需要后删除或匿名化处理。
五、我们如何使用信息
收集的信息用于：
- 提供和改进应用功能（如设备配对、图片上传、扫码解析、NFC 读写）；
- 异常诊断与性能优化；
- 基于您的明确选择提供的服务（例如同步、云端备份）。
注：本应用当前不用于定向广告或基于敏感个人信息的行为分析。如未来涉及“个性化推荐/定向推送/广告精准营销”，将明确告知并提供关闭开关。
六、我们如何保证收集的用户信息安全
我们采用以下措施保护用户数据安全：
- 传输层安全：使用 HTTPS 等安全通道传输数据；
- 存储安全：对敏感信息采取加密或脱敏处理（按需）；
- 权限控制：限制内部访问权限、对第三方服务签署数据处理协议；
- 运维安全：定期安全评估与漏洞修复。
尽管采取合理措施，但不存在绝对安全，若发生安全事件我们会依法律要求及早通知受影响用户并采取补救措施。
七、您如何管理个人信息（用户权利）
您可以：
- 在应用内管理或删除您的账户信息（如头像、昵称、已保存的 WiFi 信息等）；
- 请求导出或删除我们存储的个人信息（通过下文联系方式提出请求）；
- 对我们要求的一些权限（相机、相册、NFC、存储）在操作系统层进行允许或拒绝。
我们将在合理期限内回应您的请求（如验证身份以防止滥用）。
八、未成年人保护
本应用面向所有人群。若您为未成年人（未达法定年龄），建议在监护人同意并在监护人指导下使用本应用，并请监护人协助阅读本隐私政策。若发现未经监护人同意的未成年人个人信息被收集，请联系我们，我们会及时处理。

附：本政策的适用范围与声明
本隐私政策适用于本应用及其 Android/iOS 版本。如您还使用我们的其它服务（如网页端或第三方产品），其数据处理可能有单独的隐私政策。若使用第三方服务（SDK）收集的个人信息，第三方隐私政策可能另行适用。
1. How We Collect and Use Your Personal Information
We collect and process personal information only to the minimum extent necessary to provide the app’s features. Below are the types of information that may be collected or processed and their purposes:
1) NFC Tags and Device Identifiers
When you use the “Read/Write NFC” feature, the app may read or write text/JSON data stored on an NFC tag as well as the tag ID, for purposes such as device pairing, importing device information, or writing configuration.
2) Camera and QR Scanning
When you use QR scanning or take photos, the app uses the camera to capture images in order to decode QR codes or upload images.
3) Photo Library / Media Access
When you select or upload an image from your photo library, the app accesses only the image file(s) you explicitly choose.
4) External Storage (Legacy Android Compatibility)
To support certain older Android versions, the app may request permission to read from or write to external storage when needed (only for actions you explicitly initiate, such as saving or importing files).
5) Clipboard
The app provides “Copy to Clipboard” features. Content is written to the clipboard only when you tap a copy action. The app does not read your clipboard in the background.
6) Network and Uploads
The app may upload images, device information, or NFC read results over the network to provide services (for example, device binding or cloud features). Such transfers may include network metadata such as IP address.
- IMEI / IMSI / ICCID / Android ID / OAID
- Contacts, SMS messages, call logs
- GPS location (no location permissions requested)
- Microphone recordings (no audio recording permissions requested)
- Biometric data (fingerprint/face)
2. Cookies and Similar Technologies
We may use cookies, HTTP cache, and local storage (such as SharedPreferences, app cache, get_storage, etc.) and similar technologies to:
- Maintain sessions and remember preferences;
- Help diagnose and fix issues;
- Improve user experience (for example, using HTTP request traces to determine whether images are fetched from the network).
If we introduce third‑party SDKs in the future (for analytics or advertising) that use cookies or tracking technologies, we will disclose them here and within the app and provide relevant controls where applicable.
3. Sharing, Transfer, and Public Disclosure
We do not sell or rent personal information to unrelated third parties. We may share information only in the following circumstances:
- With your explicit authorization and consent;
- With service providers necessary to deliver features you choose (such as image storage or third‑party analytics services). We will sign data processing agreements and restrict use to service delivery purposes;
- When required by applicable laws or regulatory authorities.
4. Storage of Collected Information
We store user data using reasonable technical and organizational measures, only as needed for business purposes and compliance. Storage may include:
- Local storage: cache, database, or app‑specific storage (only what is necessary);
- Server storage: for synchronization or backup, data may be transmitted to and stored on our servers protected by server security policies.
When data is no longer needed, we will delete it or anonymize it.
5. How We Use Information
Collected information may be used to:
- Provide and improve app features (device pairing, image upload, QR decoding, NFC read/write);
- Diagnose issues and optimize performance;
- Provide services you explicitly choose (such as sync or cloud backup).
Note: The app does not currently use sensitive personal information for targeted advertising or behavioral analysis. If we introduce personalized recommendations, targeted push, or advertising‑related processing in the future, we will clearly inform users and provide opt‑out controls.
6. Information Security
We take measures to protect user data, including:
- Secure transmission: HTTPS or similar secure channels;
- Secure storage: encryption or masking of sensitive data where needed;
- Access control: limiting internal access and requiring data processing agreements for third‑party services;
- Operations security: periodic assessments and vulnerability remediation.
No system is absolutely secure. If a security incident occurs, we will notify affected users and take remedial actions as required by law.
7. Your Rights and Choices
You may:
- Manage or delete your account information within the app (such as avatar, nickname, saved Wi‑Fi info, etc.);
- Request export or deletion of personal information we store (via the contact methods below);
- Allow or deny certain permissions (camera, photos, NFC, storage) at the operating system level.
We will respond within a reasonable period (and may verify identity to prevent abuse).
8. Children’s Privacy
This app is intended for users of all ages. If you are a minor, we recommend using the app with the consent and guidance of a guardian, and that the guardian helps review this Privacy Policy. If we discover that a minor’s personal information has been collected without guardian consent, please contact us and we will address it promptly.
9. Contact Us
If you have questions, complaints, or requests regarding this Privacy Policy or your personal information, please contact us:
- Developer/Data Controller: yulongwei@dyesl
- Email: yulongwei@digiholo.cn
- Address: 浙江省杭州市拱墅区广利大厦1210
10. Changes to This Policy
If there are material changes, we will notify you in advance within the app and update the effective date at the top of this page. For non‑material updates, we will update this page and provide in‑app notice when necessary.
Appendix: Scope
This Privacy Policy applies to this app and its Android/iOS versions. If you use other services we provide (such as a web version or third‑party products), separate privacy policies may apply. If third‑party services (SDKs) collect personal information, their privacy policies may apply.
