Privacy Policy隐私政策
Based on the app's privacy policy (2026-09-27); this page prepared 2026-10-18 and aligned with the 1.0.6 behavior. 基于应用隐私政策（2026-09-27）；本页于 2026-10-18 制作，并按 1.0.6 实际行为对齐。
PRIVACY_POLICY.md on three points — the removed daily-reminder feature, the language setting, and the current search provider (DeepSeek Search, with Tavily retained as fallback). Those are listed under “待补充事项” in the delivery notes.
说明：本页反映 MiraBrief 1.0.6 的真实数据处理方式，与应用内 PRIVACY_POLICY.md 有三处不同——已移除的每日提醒功能、语言设置、以及当前搜索供应商（DeepSeek Search，Tavily 为保留备选）。这些已列入交付说明的“待补充事项”。
1. What MiraBrief is1. 产品简介
MiraBrief is a “private AI daily newspaper” app. Based on the identity and interests you fill in, it automatically searches the latest public information each day and uses AI to filter and organize it into a briefing with introductions. No registration, no login.MiraBrief 是一款「私人 AI 每日报纸」App：根据你填写的身份与关注内容，每天自动搜索最新公开信息，用 AI 筛选并整理成一份带导读的日报。无需注册、无需登录。
2. Data stored locally2. 本地保存的数据
The following data is stored only on your device (in-app storage) and is not uploaded to any server for long-term storage:以下数据只保存在你的设备本地（应用内存储），不会上传到服务器长期保存：
- Your identity / interests / dislikes (profile)你的身份 / 兴趣 / 不喜欢设置（profile）
- The AI's understanding of youAI 对你的理解结果（aiUnderstanding）
- Likes / dislikes and long-term preferences点赞 / 点踩与长期偏好（preferences）
- The generated briefings生成的日报内容（reports）
- App settings (theme, language, etc.)应用设置（主题、语言等）
3. Data sent to the AI service3. 发送给 AI 服务的数据
To generate the “AI understanding” and the briefing, we send your filled-in identity / interests / dislikes, the AI understanding, the titles of articles you liked or disliked, and the searched news titles and snippets, through our own relay service to the AI provider DeepSeek, for content generation. We do not send your real name, device information, or location.为了生成「AI 理解」和日报，我们会把你填写的身份 / 兴趣 / 不喜欢、AI 理解结果、你点赞点踩过的文章标题、以及搜索到的新闻标题与摘要，通过我们自己的中转服务发送给 AI 服务商 DeepSeek，用于生成内容。我们不会发送你的真实姓名、设备信息或位置。
4. Data sent to the search service4. 发送给搜索服务的数据
We send search queries generated from your interests, through the relay service, to a search provider to retrieve public information. The production configuration currently uses DeepSeek Search; Tavily is retained as a fallback provider.我们会把根据你的兴趣生成的搜索词，通过中转服务发送给搜索服务，用于检索公开资讯。生产环境当前使用 DeepSeek Search；Tavily 为保留的备选供应商。
5. The relay service (Gateway)5. 中转服务（Gateway）的作用
To protect API keys, all of the above requests are forwarded through our own relay service. It does not store your briefing content, search queries, or interests; it only records de-identified request counters for rate limiting and quota control.为了保护 API 密钥，上述所有请求都经过我们自己部署的中转服务转发。该中转服务不保存你的日报正文、搜索词或兴趣内容，只记录去标识化的请求计数用于限流与配额控制。
6. Anonymous device identifier6. 匿名设备标识（device token）
On first launch the app generates a random “device identifier” (32 hexadecimal characters) locally and sends it with requests, used only for request authentication, rate limiting, and quota bucketing. It is not linked to your real identity and is not an authentication; it is regenerated after clearing data or reinstalling.App 首次启动会在本地生成一个随机「设备标识」（32 位十六进制），随请求发送给中转服务，仅用于请求鉴权、限流与配额分桶。它不关联你的真实身份，也不是身份认证；清除数据或重新安装后会自动重新生成。
7. Other third-party sources7. 其他第三方数据源
- Hacker News / arXiv: accessed directly for public information; these requests do not carry your personal information.Hacker News / arXiv：直接访问公开信息源获取资讯，请求不携带你的个人信息。
- Google Fonts: the app's interface fonts may load from Google Fonts (which sends Google your IP address, a routine part of network requests).Google Fonts：应用界面字体可能从 Google Fonts 加载（会向 Google 发送你的 IP 地址，属网络请求的常规信息）。
8. What we do not collect8. 我们不收集的信息
We do not collect device identifiers (IMEI / OAID / Android ID), precise location, contacts, SMS, photos, microphone, camera, or call logs; and we integrate no analytics, advertising, or crash-reporting SDKs.我们不收集：设备标识符（IMEI / OAID / Android ID）、精确位置、通讯录、短信、相册、麦克风、摄像头、通话记录；不接入任何统计、广告或崩溃上报 SDK。
9. Data retention9. 数据保存期限
- Briefings: kept locally for the last 90 days, then deleted.日报：本地保留最近 90 天，超出自动删除。
- Article cache: up to 500 entries, oldest evicted first.文章缓存：最多 500 条，自动淘汰最旧的。
- Other preferences and AI understanding: kept until you clear them.其余偏好与 AI 理解：保留至你主动清除。
10. Deleting your data10. 用户数据删除
In Preferences → Data → Clear all data, you can delete all local data (identity, interests, AI understanding, feedback, briefings, cache, device identifier) in one tap; afterwards the app returns to onboarding. You can also uninstall the app to delete everything.你可以在「我的偏好 → 数据管理 → 清除全部数据」一键删除全部本地数据（身份、兴趣、AI 理解、反馈、日报、缓存、设备标识），删除后 App 回到初始引导流程。也可以直接卸载应用以删除全部数据。
11. Security11. 安全措施
