一、我们处理的信息
多时不要求您注册账号，也不主动收集您的姓名、电话号码、电子邮件地址、精确位置、联系人或其他与使用计时器无关的个人信息。
您主动保存的信息
- 计时器名称、预设时长、计时状态、完成记录和洞察统计数据。
- 您在“我的”页面设置的昵称、主题、语言、提醒、后台计时、屏幕常亮和每日目标等偏好。
- 您主动从系统照片图库选择的头像图片，或用于显示该图片的本地文件路径。
系统权限相关信息
当您主动使用对应功能时，本应用可能请求照片图库权限以更换头像，请求通知权限以发送计时到期提醒，并调用系统的声音、震动和屏幕常亮能力。上述能力只用于完成您发起的功能，不会将相关内容上传给我们。
本应用不使用定位、通讯录、麦克风或相机采集功能，也不收集 IP 地址、设备唯一标识符、广告标识符、跨应用行为或崩溃分析数据。
1. Information We Handle
Duoshi does not require an account and does not proactively collect your name, phone number, email address, precise location, contacts, or other information unrelated to timer use.
Information You Choose to Save
- Timer names, preset durations, timer states, completed sessions, and insight statistics.
- Preferences you set in Profile, such as nickname, theme, language, reminders, background timing, screen-awake mode, and daily goal.

System Permissions
When you use the relevant features, the App may request photo-library access to change your avatar, notification permission for timer-completion reminders, and access to system sound, vibration, and screen-awake capabilities. These capabilities are used only to provide the feature you requested and are not uploaded to us.
The App does not use location, contacts, microphone, or camera collection features, and does not collect IP addresses, device identifiers, advertising identifiers, cross-app activity, or crash analytics.

三、信息存储与安全
计时器、完成记录、设置、昵称和头像相关数据默认保存在您的设备本地。多时没有账号系统，也没有将这些数据上传到我们的服务器或云端数据库。
我们通过应用沙盒和系统提供的本地存储机制保护应用数据。由于任何电子存储都不能保证绝对安全，请妥善保管您的设备及系统解锁凭证。
删除应用或清除应用数据可能会删除设备中保存的计时器、完成记录、设置和本地头像数据。建议您在删除前确认是否仍需保留相关信息。
3. Storage and Security
Timers, completed sessions, preferences, nickname, and avatar-related data are stored locally on your device by default. Duoshi has no account system and does not upload this data to our servers or a cloud database.
We rely on the app sandbox and system-provided local storage mechanisms to protect app data. Because no electronic storage can be guaranteed absolutely secure, please protect your device and its unlock credentials.
Deleting the App or clearing its data may remove timers, completed sessions, preferences, and the locally stored avatar data from your device. Please confirm whether you need to retain this information before deleting the App.
四、信息共享与第三方服务
本应用不会出售、出租、交换或向第三方提供您的本地计时器、完成记录、昵称或头像数据。本应用不集成广告、社交登录、第三方分析、云存储或跨应用跟踪服务。
本应用仅使用系统提供的照片图库、通知、声音、震动和屏幕管理能力来完成您主动使用的功能。系统服务可能依照其自身规则处理必要的技术信息，建议您同时阅读相关系统服务的隐私说明。
如法律法规、司法程序或主管机关依法要求，我们可能在法律要求的范围内处理或披露必要的信息。
4. Sharing and Third-Party Services
The App does not sell, rent, exchange, or provide your local timers, completed sessions, nickname, or avatar data to third parties. The App does not integrate advertising, social login, third-party analytics, cloud storage, or cross-app tracking services.
The App uses only system-provided photo-library, notification, sound, vibration, and screen-management capabilities to provide features you actively use. System services may handle necessary technical information under their own rules; please also review the applicable system privacy notices.
We may process or disclose necessary information when required by applicable law, judicial process, or a competent authority.
