Sale & Cancellation Terms — physmat.org

These Sale & Cancellation Terms govern the purchase of paid features on physmat.org (the "platform", "we", "us"). They form part of your agreement with us when you buy a paid feature and should be read alongside our Terms of Service, our Refund Policy and our Privacy Policy. Where these terms touch how we handle personal data, the Privacy Policy governs.

This service is offered in the United Kingdom. It is not offered in the United States at this time, and we do not target US users.

1. What is sold

The core platform — the problem bank together with answer submission and grading — is available to every account. These Sale & Cancellation Terms apply to the paid features sold on top of the core service:

• Subscription access to paid features, on a recurring (subscription) basis.
• The optional AI tutor add-on — an entitlement-gated paid feature that is off until purchased. A child can use the platform fully without it. What the tutor is, what it sends to the AI model, and its limitations are described in the AI Tutor Notice and the Privacy Policy §5.

to be confirmed The AI tutor is the paid add-on confirmed in the platform today; any other paid feature is described where it is offered.

2. Who may buy

A paid subscription is bought by an adult payer who manages the account(s) it covers:

• Parent payer. A parent or guardian buys a subscription for the child account(s) they manage.
• School payer. A school buys a subscription covering its enrolled pupils.

A subscription covers one or more child accounts (seats) linked to the payer. A child does not buy a subscription; the adult payer enters into the purchase on the child's behalf and agrees to these terms.

3. Pricing, plans and billing cycle

• Plans and prices. Two subscription plans are offered: a parent subscription and a school subscription. to be confirmed The plans, prices and what each one includes are shown at the point of purchase before you confirm. Prices are shown inclusive of any applicable VAT.
• Billing cycle. A subscription is billed in advance for each billing period. You can choose a monthly or an annual billing cycle. The billing cycle for your plan is shown at the point of purchase.
• Renewals. Unless cancelled, a subscription renews automatically at the end of each billing period, and the payment method on file is charged for the next period at the then-current price for that plan. You can cancel at any time (see §6).
• Price changes. If we change the price of a plan, we will give you at least 30 days' advance notice before the change takes effect on your subscription, so you can cancel before being charged the new price if you do not wish to continue.
• Failed payments. If a renewal payment fails, we may retry the payment and may suspend access to the paid feature until payment succeeds. We will not silently keep charging a method that is failing. to be confirmed

4. How payment is taken — card data

Paid features are paid for through Stripe. Card details are entered directly with Stripe; we never see or store card numbers or payment-method details. We hold only Stripe identifiers (a customer reference and a subscription reference) and the status of a subscription, which we use to manage access. See the Privacy Policy §6 for how this is handled.

5. Your right to cancel (cooling-off) — UK Consumer Contracts Regulations 2013

A subscription bought by a consumer at a distance (online) is a distance contract under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. Those Regulations give a consumer, in general, a 14-day cancellation ("cooling-off") right beginning the day after the contract is concluded, during which the consumer may cancel for any reason.

Digital content and immediate-service nuance. The platform's paid features — including the AI tutor — are supplied as digital content / a digital service that begins as soon as you buy it. Under the 2013 Regulations, where a consumer expressly asks for the service to begin during the 14-day period and acknowledges that, by doing so, they will lose the cancellation right once supply has begun (for digital content, once download/streaming has started; for a service, once it has been fully performed), the 14-day cancellation right may not apply, or may be reduced.

Our position is Position A — the 14-day cancellation right is preserved. We do not rely on the immediate-supply waiver by default: you are not required to consent to immediate supply with loss of the cancellation right, so you keep the full 14-day cooling-off right and may cancel within that window for any reason.

For completeness, the alternative is recorded: under the 2013 Regulations, where a consumer expressly asks for immediate supply and acknowledges that they thereby lose the cancellation right, that right may be lost or reduced once supply has begun. We do not adopt that approach by default.

Nothing here removes any cancellation right you have that cannot be excluded by law.

6. How to cancel, and the effect of cancelling

• How to cancel. You can cancel a subscription to be confirmed and/or by contacting us at mail@physmat.org. You can cancel at any time. We will confirm a cancellation.
• Effect of cancelling.
• A cancellation during a valid cooling-off period (§5) is handled under the 2013 Regulations and the Refund Policy.
• A parent or school may also stop using the service and delete an account at any time; what happens to data on deletion is described in the Privacy Policy §9.

7. Your statutory rights are unaffected

Nothing in these terms removes or reduces your statutory rights as a consumer, including your rights under the Consumer Rights Act 2015 (for digital content: that it be of satisfactory quality, fit for purpose, and as described, with remedies if it is not) and under the Consumer Contracts Regulations 2013. Where anything in these terms conflicts with a right you have that cannot be excluded by law, that statutory right prevails.

8. Related documents

• Refunds — when and how a refund is given is set out in the Refund Policy, which is read together with these terms.
• General terms of use — the Terms of Service govern your use of the platform overall (see §7 there on payments and subscriptions).
• Personal data — how we handle data, including Stripe payment references, is set out in the Privacy Policy.

9. Governing law and disputes

These terms are governed by the laws of England and Wales, and the courts of England and Wales have jurisdiction. Your statutory rights as a consumer, including the right to bring proceedings in your country of residence where that right applies, are unaffected.

If something goes wrong, please contact us first at mail@physmat.org so we can try to put it right. If we cannot resolve it between us, you may be able to refer the dispute to alternative dispute resolution (ADR) or an ombudsman scheme where one applies. You may also have the right to ask your bank or card provider for a chargeback on a payment made through Stripe. None of this removes any statutory right you have to take a matter to court.

10. Changes to these terms

We may update these terms. If we make a material change, we will tell affected users before it takes effect; a change does not alter the terms that applied to a purchase already made. The "last updated" date at the top shows the current version.
