Terms and conditions

The videos and the quizzes are free. There is no pass, no subscription and no trial: an account is all you need, and you will never be charged for watching.

You may choose to support the project with a one-off contribution. That is a donation, not a purchase: it unlocks nothing, because nothing is locked, and it gives you no particular rights over the service.

A live session is the one thing that is paid: a single purchase of one seat in one session, because it is time set aside for you.

One account, one person. Sharing your login, your password, or a session link with anyone else is not allowed.

Each account may be used on up to two devices — a laptop and a phone. Everything is free, so counting accounts is how we know how many students use the site, and one login shared around a whole section makes that count meaningless.

Downloading, recording, re-uploading or redistributing the videos is not allowed. They are licensed to you for your own study, not transferred to you.

If an account is clearly being shared or the videos are being redistributed, we may suspend it. Where that happens we will tell you why and, if you disagree, look at it again.

When you book a seat, your card is authorised, not charged. The money is held by your bank and nothing leaves your account.

We take the payment three days before the session starts. Until that moment you can cancel your seat yourself from the session page, the hold is released, and you pay nothing at all. No fee, no form, no waiting for a refund — because there is nothing to refund.

Once the payment has been taken — inside those last three days — the seat is no longer cancellable, because at that point the time has been set aside for you and cannot realistically be resold.

If a group never fills, nobody is charged. The authorisation simply lapses.

One exception, in your favour: a session booked more than a week ahead may have to be charged earlier, because a card authorisation does not last indefinitely. If that happens and you then cancel with more than three days to go, we refund you in full — the promise above still holds.

If we cancel a session, for any reason at all, you get your money back in full. Where it was only held, the hold is released immediately. Where it was charged, it is refunded.

A contribution is voluntary and buys nothing. It creates no account level, no priority, no right to new content, and no obligation on our side beyond running the site in good faith.

If you contributed by mistake — the wrong amount, twice, or with a card that is not yours — tell us and we refund it. Use the contact page; a screenshot of the Stripe receipt makes it quick.

Nothing in these terms removes a right that the law of your country gives you as a consumer. Where local law and anything written here disagree, local law wins.

We will try to keep the site up and the videos playing, and we will fix what breaks. We cannot promise it is never down: the site depends on other companies (hosting, video delivery, payments) and they have bad days too.

The videos are study material made by one person. They are not official course material, they are not endorsed by your university, and they are not a guarantee of a grade. If they contradict your lecturer, believe your lecturer — they are the one marking.

We do not promise that any particular course, video or session will stay available forever. If we withdraw something you paid to access during your term, tell us and we will make it right.

Be civil to whoever else is in the room. Sessions are for working on the material.

Do not record a session without asking everyone in it first. Other people's questions are not yours to publish.

We may remove someone from a session, and refund them, if they make it unusable for the others.

You can close your account at any time, yourself, from your account page, or by asking us. We delete your personal data as described in the privacy policy. Closing the account does not refund a past contribution and does not cancel a live session you booked — cancel that from its own page first.

We may change these terms. If a change matters — anything about money, access or your data — we will say so by email rather than quietly editing this page. The date at the top always tells you when it last changed.

Changes never apply retroactively to a seat you have already bought. What you agreed to when you paid is what you get.

Anything at all — a broken video, a contribution sent by mistake, a complaint, a question about your data — use the contact page. A real person reads it.
