先说清楚

使用网站不需要注册。我们不设置第一方 Cookie，也没有广告追踪器。浏览器会记住你选的语言和主题；本次会话中选中的课程也会暂存在浏览器里。提交评价时，浏览器会保存一个随机令牌，帮助防止重复评价。我们不出售个人信息，也不用它来投放定向广告。

我们处理的信息

• 你主动提交的查询词、国家代码、指标、日期、DOI、州代码和结果条数。
• 浏览器本地界面状态：语言与主题偏好保存在 localStorage；最多三项候选课程保存在 sessionStorage，并在会话结束时清除。保存这些界面状态本身不会把它们发送到服务端。
• 你主动提交的分项评分、可选文字评价、语言、CRICOS 实体身份，以及随机评价者令牌的 SHA-256 摘要。原始随机令牌仅保存在你的浏览器本地存储中。
• 为限制滥用，服务端会把 Cloudflare 提供的连接 IP 与仅保存在服务端的随机密钥组合后计算 SHA-256 速率键；评价表不保存原始 IP。
• Cloudflare 为传输、安全和运行服务通常需要处理的网络与设备元数据，例如 IP 地址、时间、请求路径、用户代理和安全事件。
• 服务端验证结果、错误和性能记录，用于可靠性、安全和故障排查。

查询去向

浏览器把查询发给 DegreeSignal 的同源 Cloudflare Worker。根据你选择的来源，Worker 可能把必要的查询参数转发给 World Bank、Crossref 或澳大利亚 data.gov.au。CRICOS 与 IPEDS 快照查询在绑定的 D1 索引内完成。第三方来源按各自隐私条款处理请求。

我们为什么使用这些信息

查询信息用于返回结果和核对来源；运行记录用于防止滥用和排查故障。评价提交后先由我们审核，只有通过审核的评分和文字才会公开。网站没有接入第三方分析、广告或营销工具。运行日志和评价的保存时间取决于服务配置及审核、安全和维护需要；目前没有统一的固定删除期限。

隐私问题

目前没有账户资料可供导出或删除。如果你想询问个人信息的处理方式，请发邮件至 privacy@degreesignal.com。

The short version

You can use the site without an account. We do not set first-party cookies or use advertising trackers. Your browser remembers your language and theme, and temporarily keeps shortlisted courses for this session. If you post a review, it also stores a random token to help prevent duplicate reviews. We do not sell personal information or use it for targeted ads.

Information processed

• Queries, country codes, indicators, dates, DOIs, state codes, and row limits you submit.
• Local interface state: language and theme preferences are stored in localStorage; up to three shortlisted courses are stored in sessionStorage and cleared when the session ends. Saving these interface states does not itself send them to the server.
• Dimensional ratings, optional written reviews, locale, CRICOS entity identity, and a SHA-256 digest of a random reviewer token that you choose to submit. The original random token remains in your browser's local storage.
• To limit abuse, the server combines the connecting IP supplied by Cloudflare with a server-only random secret and computes a SHA-256 rate key; the review table does not store the raw IP.
• Network and device metadata Cloudflare normally needs for delivery, security, and operations, such as IP address, time, request path, user agent, and security events.
• Server-side validation outcomes, errors, and performance records used for reliability, security, and diagnosis.

Where queries go

Your browser sends queries to the same-origin DegreeSignal Cloudflare Worker. Depending on the selected source, the Worker may forward necessary query parameters to World Bank, Crossref, or Australian data.gov.au. CRICOS and IPEDS snapshot searches run against the bound D1 indexes. Third-party sources process requests under their own notices.

Why we use it

We use queries to return results and check sources, and operational records to prevent abuse and investigate errors. Reviews are moderated before publication; only approved ratings and text become public. The site has no third-party analytics, advertising, or marketing tools. How long logs and reviews are kept depends on service settings and moderation, security, and maintenance needs. There is currently no single fixed deletion period.
