Privacy Policy — Interview Rehearsal

Last updated: 2026-09-26 · Publisher: Number & Reason (Hangzhou) Digital Technology Co Ltd (数与理（杭州）数字科技有限公司)

Summary: we collect no data and run no servers. What you type goes directly from your browser to the AI provider you choose, using your own key.

• Your API key is stored in your browser's local extension storage on this device (unencrypted, like other browser extension data) and is sent only to the AI provider it belongs to. You can delete it in Settings at any time.
• What is sent to your AI provider. The job description, your optional background notes, the interview questions and your answers — only when you start a practice session or submit an answer. The provider's own privacy policy and terms apply to that data. The extension talks to no other server.
• Reading a page. Only when you click "Use this page as the job description", the extension reads the selected text or main text of the current tab once and puts it in an editable box. It refuses to read video-meeting and online-assessment sites.
• Practice history (questions, your answers, feedback) is kept on this device only, by default the latest 50 sessions. You can turn history off, delete single sessions, or clear everything. Exports never include your key.
• No tracking. No analytics, tracking or advertising code.
• Uninstalling removes the key, settings and history from this device.
• Children. The extension is not directed at children and collects no data from anyone.
• Changes. If this policy changes, the new version will be published at this address with a new date.

我们不收集任何数据，也不运营服务器；你输入的内容直接从你的浏览器发给你选择的 AI 服务商，使用你自己的 Key。API Key 保存在本机浏览器的扩展存储中（与其他扩展数据一样未加密），只发给它所属的服务商，可随时在设置中删除。只有在你开始练习或提交回答时，职位描述、你可选填写的背景、题目和回答才会发给你选的服务商，并受其隐私政策和条款约束；扩展不与其他服务器通信。只有你点击“用这个页面作为职位描述”时，扩展才读取一次当前页的选中文字或正文并放进可编辑框；视频会议和在线测评网站拒绝读取。练习记录只保存在本机（默认最近 50 场），可关闭、单删或全部清空；导出文件不含 Key。无统计、追踪或广告代码。卸载即删除本机的 Key、设置和记录。联系：jileilei@shuyuli.cn
