隐私政策
最后更新: 2026 年 9 月 1 日
「回头看看」是由 iftech 开发的一款帮助用户减少手机干扰的 App。我们非常重视你的隐私,原则很简单:我们不收集任何数据。
我们不收集数据
- App 没有自己的服务器,不上传、不收集、不分析任何用户数据。
- 没有账号系统,没有第三方统计 SDK,没有广告。
数据在哪里
- 微信读书 API Key:仅保存在你的设备本地,用于向微信读书官方接口同步你自己的划线。
- 划线内容与封面图:从微信读书同步后仅保存在设备本地,用于锁定页展示。
- 屏幕使用时间:App 通过 Apple 官方 Family Controls API 执行锁定;授权与执行均由 iOS 系统管理,App 无法读取你的应用使用记录。
网络请求
App 仅在同步时直接连接微信读书官方接口(i.weread.qq.com)获取你自己的划线与书籍封面,该过程受微信读书的隐私条款约束。除此之外没有任何网络请求。
数据删除
删除 App 即删除全部本地数据(API Key、划线、封面、锁定状态)。
Privacy Policy
Last updated: September 1, 2026
Huitou Kankan ("Look Back") is developed by iftech. Our principle is simple: we do not collect any data.
No Data Collection
- The app has no backend server and does not upload, collect, or analyze any user data.
- No accounts, no third-party analytics SDKs, no ads.
Where Your Data Lives
- WeChat Reading API Key: stored only on your device, used to sync your own highlights from the official WeChat Reading API.
- Highlights and book covers: stored only on your device after syncing, used on the shield screen.
- Screen Time: shielding is performed via Apple's official Family Controls API; authorization and enforcement are managed by iOS, and the app cannot read your app usage history.
Network Requests
The app only connects directly to the official WeChat Reading API (i.weread.qq.com) during sync to fetch your own highlights and book covers, which is governed by WeChat Reading's privacy terms. There are no other network requests.
Data Deletion
Deleting the app deletes all local data (API key, highlights, covers, shield state).
