Privacy Policy / 隐私政策

Effective 3 November 2026. This policy covers the 3.4.0 pre-release AI and membership service; the Edge store version remains governed by its published disclosures until 3.4.0 is released.

What we process

Your email address, sign-in session, trial and membership status.
The English word, phrase or sentence you deliberately request for analysis, plus limited nearby caption context needed to interpret it.
Service-security data such as rate-limit identifiers, request timing, quota use and error logs.
Payment order status if paid service is opened later. We do not currently collect money or payment-card details.

How it is used

We use this data to sign you in, return AI learning explanations, enforce quotas, prevent abuse, support purchases and diagnose failures. AI requests are sent to the configured model provider through our Cloudflare Worker; API keys remain server-side.

Storage and control

Saved words, sentences and My Learning items are stored locally in your browser profile unless you export them. Server-side accounts, sessions, entitlements, quota events and cache entries are stored in Cloudflare services. Analysis cache entries are set to expire after 30 days; sessions expire after 30 days; email codes expire after 5 minutes and are single-use. Operational records may remain until routine maintenance removes them.

You may remove local learning items in the extension, sign out to revoke the current session, or contact us to request account-data assistance. Do not submit sensitive personal information in text selected for AI analysis.

我们处理的信息

邮箱地址、登录会话、试用与会员状态。
您主动请求分析的英文单词、短语或句子，以及理解语义所必需的少量邻近字幕。
用于频率限制、额度、安全与故障排查的请求时间、使用记录和错误日志等信息。
未来开放付费服务后的订单状态。目前不收款，也不处理银行卡资料。

使用目的

这些信息用于登录、返回 AI 学习解释、执行额度与防滥用限制、支持购买流程及排查故障。AI 请求经 Cloudflare Worker 发送给已配置的模型服务商，API 密钥仅保存在服务端。

保存与控制

收藏的单词、句子与 My Learning 内容默认仅保存在浏览器配置中，除非您自行导出。账号、会话、权益、额度事件与缓存保存在 Cloudflare 服务中。分析缓存设置为 30 天后过期；会话 30 天后过期；邮箱验证码 5 分钟后过期且仅能使用一次。运维记录可能保留至例行维护清理。

您可以在插件内删除本地学习内容、退出登录撤销当前会话，或联系我们协助处理账号数据。请勿在提交 AI 分析的文本中包含敏感个人信息。
