Privacy policy

This policy explains what ClassHin (“we”) collects when you use classhin.com, why we collect it, who helps us process it, and the choices you have. We collect only what we need to run your classes.

What we collect

Your account

  • Name and email address, used to create your account, sign you in and contact you about your classes.
  • Password, which we store only as a one-way hash. We never see or store your actual password.
  • Google sign-in: if you choose it, Google shares your name, email address and a Google account identifier with us. We don't get access to your Google data beyond that.
  • Your role (student, teacher or administrator) and the courses you are enrolled in or teach.

Your classes

  • Live chat messages you send in a classroom. The class teacher, administrators and other learners in that class can see them, and teachers can hide messages.
  • Lecture recordings. We record the teacher's camera, microphone and shared screen. If the teacher invites a learner to speak and the learner unmutes, their voice is heard by the class and is part of the recording. Learners' cameras are never recorded.
  • Learners' cameras in live classes. A learner can choose to turn on their camera. Only the teacher sees it; other learners never do. It is not recorded or stored. The teacher can turn a learner's camera or microphone off, but never on.
  • Announcements and files that teachers post in a course, such as images, PDFs and worksheets.

Payments

Payments are handled by Razorpay (for customers in India) and Dodo Payments (for everyone else). They collect your card, UPI or bank details directly; we never receive or store them. We keep a record of what you bought, how much you paid and when.

Technical data

  • A session cookie that keeps you signed in. It is strictly necessary and is removed when you sign out or it expires.
  • Your light or dark theme choice, saved in your own browser.
  • Limited security records, such as sign-in attempts used for rate limiting, and a log of administrator changes to accounts and courses.

We do not use advertising cookies, analytics trackers or third-party tracking pixels, and we do not sell your data.

Who processes data for us

  • Resend sends account emails such as verification codes and password reset links.
  • Google Firebase (Firestore) stores account, course and class data and classroom chat messages.
  • Hugging Face stores private backups of lecture recordings, in a private repository only ClassHin can access.
  • Google provides the optional “Continue with Google” sign-in.
  • Razorpay and Dodo Payments process payments.
  • Our hosting provider runs the website and stores recordings and course files.
  • Cloudflare carries live class video and audio between the teacher and learners. It does not store it.
  • If a teacher turns on voice commands (for example “unmute Asha”), their browser's speech recognition service (Google, in Chrome) processes the teacher's microphone audio while it is on. ClassHin only receives the recognised command.

These providers may process data outside your country. We use them only to run ClassHin, not for their own marketing.

Children

Many of our learners are children. A parent or legal guardian must create and manage the account for any learner under 18, and by doing so confirms that they consent to the processing described here. Children never need to share their camera or microphone in class: both are off unless the learner turns them on, and a microphone only after the teacher invites them to speak. Only enrolled learners and teachers can see a course's chat, recordings and files. A parent or guardian can ask us to see or delete their child's data at any time.

How long we keep it

  • Account data stays for as long as your account is open. We delete it within 30 days of a deletion request.
  • Recordings, chat and course files stay for as long as the course runs, or until you ask us to delete them.
  • Payment records are kept for as long as tax and accounting law requires.
  • Unused verification codes, password reset links and sign-in sessions expire automatically.

Your rights

You can ask us to give you a copy of your data, correct it, delete it, or stop processing it. Depending on where you live, you may also have rights under laws such as India's Digital Personal Data Protection Act, the GDPR or the CCPA, including the right to complain to your data protection authority. Email support@classhin.com from your account's email address and we'll respond within 30 days.

Security

Passwords are hashed, sessions use secure, HTTP-only cookies, and course content is only served to signed-in accounts that are allowed to see it. No system is perfectly secure; if a breach affects your data, we will tell you and the relevant authorities as the law requires.

Changes

If we change this policy in a way that matters, we'll update the date above and let you know by email or in the app. See also our terms of service and refund policy.
