Privacy Policy
Last updated: November 15, 2026
Short version: you can use SchedraOSU without an account. If you sign in with Google to rate professors, we keep only an anonymous ID, your ratings and anything you choose to write. We never show your name, email or grade to anyone.
Without signing in
- Your course list and schedule are saved only in your own browser (localStorage). They are not sent to our database.
- When you search a course, our server fetches public data from OSU Class Search, Rate My Professors and The Grade Guide and caches it. We do not log which courses you search together with who you are.
- We do not use advertising trackers or sell any data.
When you sign in with Google
- Google tells us your Google account ID, name and profile picture. We turn the account ID into a one-way anonymous ID (a keyed hash) and store only that in our database. We never store your email address.
- Your first name and profile picture are kept only in a signed login cookie in your browser so we can show “Signed in as …”. The cookie expires after 30 days or when you sign out.
- We request only basic sign-in information. We cannot read your Gmail, Drive or any other Google data.
Ratings and reviews
- When you rate a professor we store: the anonymous ID, course, professor, star rating, the grade you report, the term (optional) and the review text (optional).
- Other people see averages (stars and average GPA) and individual star ratings, terms and review text — never your name, email or individual grade. Note that when a professor has only one rating, the average GPA equals that student’s reported grade.
- You can edit or delete your ratings at any time from “Reviews → My reviews”.
- Students can report reviews. Reported reviews are checked by the site admin, who may hide text that contains personal attacks, contact information or spam.

隐私政策
最后更新：2026 年 11 月 15 日
简单来说：不登录也能使用 SchedraOSU。用 Google 登录给教授评分时，我们只保存一个匿名 ID、你的评分和你自愿写的文字。我们不会向任何人显示你的名字、邮箱或成绩。
不登录时
- 你的课程列表和课表只保存在你自己的浏览器里（localStorage），不会传到我们的数据库。
- 搜索课程时，服务器会从 OSU Class Search、Rate My Professors 和 The Grade Guide 获取公开数据并缓存。我们不会把你搜了哪些课和你的身份关联起来记录。
- 我们不使用广告追踪，也不出售任何数据。
用 Google 登录时
- Google 会告诉我们你的账号 ID、名字和头像。我们把账号 ID 转换成不可逆的匿名 ID（带密钥的哈希），数据库里只存这个。我们从不保存你的邮箱。
- 你的名字和头像只保存在你浏览器里一个带签名的登录 cookie 中，用来显示“已登录”。cookie 30 天后或退出登录时失效。
- 我们只请求最基本的登录信息，读取不了你的 Gmail、Drive 或其他任何 Google 数据。
评分和评价
- 给教授评分时，我们保存：匿名 ID、课程、教授、星级、你填写的成绩、学期（可选）和评价文字（可选）。
- 其他人能看到平均值（平均星级和平均 GPA），以及每条评价的星级、学期和文字——不会看到你的名字、邮箱或你个人的成绩。注意：当一位教授只有一条评价时，平均 GPA 就等于那位同学填写的成绩。
- 你可以随时在“评价 → 我的评价”里修改或删除自己的评价。
- 同学可以举报评价。被举报的评价由站长审核，包含人身攻击、联系方式或广告的文字可能会被下架。
服务提供商
网站运行在 Cloudflare 上（托管和数据库），并使用 Google 登录。这些服务商只为提供相应服务而处理数据。

SchedraOSU 是学生做的独立项目，与 The Ohio State University、Rate My Professors、The Grade Guide 均无关联。
