Mission

Poray Kemon is an anonymous platform where Bangladeshi university students can share their experiences with professors and courses. The goal: course selection should not depend on a handful of WhatsApp-group opinions but on real student experience, durably indexed and searchable.

The name — "Poray Kemon" — is literally the question students already ask each other: "How does he/she teach?"

The anonymity contract

You sign in with Google to write a review, but your identity is never stored alongside what you wrote. Even if the database is fully compromised, no review can be traced back to its author.

  • The table holding review content has no user-identifying column at all — anonymity is structural, not policy-based.
  • Whether an account has reviewed a given course lives in a separate table — it holds no review content and no reference back to any specific review.
  • The two tables share no foreign key — a direct JOIN cannot re-pair them.
  • They also use different kinds of identifiers (sequential on the content side, random UUIDs on the submission side), so lining them up by sorted id order does not work either.
  • The submission table carries no per-row timestamp, so submissions cannot be matched to reviews by time.
  • Your IP address is never stored anywhere in the system.
  • Your Google email is never stored — only an opaque internal identifier.

What we store

  • Reviews: ratings, tags, and your written text — without any user attribution.
  • Account: only Google's internal ID (sub) and your display name. No email, no profile picture.
  • Who reviewed which course: to prevent duplicates — but with no link to review content.
  • Helpful votes: who voted on which review.
  • Reports: which review was reported and why — without the reporter's identity.

Content moderation

Reviews are published immediately. Content with profanity, slurs, or unsubstantiated personal accusations is auto-blocked before submission.

If 3 distinct users report the same review, it is auto-hidden pending admin review.

When a review is hidden or removed, a transparency notice is shown in its place — never a silent deletion.
