Terms of Service

Last updated: 13 November 2026

These terms apply to your use of Chemistry Reaction Schemes (“the Service”), a website that lets you draw chemical structures and generate reaction schemes with step-by-step explanations. The Service is run by Luke Whelan, a sole trader based in Ireland (“we”, “us”). By creating an account or using the Service, you agree to these terms.

1. Who can use the Service

You must be at least 16 years old, or have permission from a parent or guardian, to create an account. You are responsible for keeping your password secure and for activity on your account.

2. What the Service does, and its limits

Reaction schemes, mechanisms and explanations are generated automatically by artificial intelligence. They are intended as a study aid. They can contain mistakes, including incorrect products, structures or mechanisms. Always check results against your course materials, textbooks or a teacher.

The Service is not a substitute for professional advice. Do not rely on it for laboratory work, safety decisions, or anything where an error could cause harm or loss.

3. Plans and usage limits

• Free plan: up to 3 schemes per day.
• Pro plan: €5.99/month, VAT included, for up to 150 schemes per calendar month. Unused schemes do not carry over.

We may change plan features, limits or prices in future. Price changes will not affect a billing period you have already paid for, and we will give you notice before any price change applies to your subscription.

4. Payments and subscriptions

Pro subscriptions are sold through Link, the merchant of record service operated by Stripe. Link processes your payment, handles applicable taxes (such as VAT), and issues your receipts and invoices. Link’s own terms also apply to your purchase. We never see or store your full card details.

Your subscription renews automatically each month until you cancel. You can cancel at any time using Manage plan on the site or through your Link account. See our Refund & Cancellation Policy for details.

5. Acceptable use

You agree not to:

• use the Service for anything unlawful, or to plan the making of dangerous, illegal or controlled substances;
• try to get around usage limits, for example by creating multiple accounts or automating requests;
• interfere with, overload or attempt to gain unauthorised access to the Service;
• resell or redistribute access to the Service.

We may suspend or close accounts that break these rules.

6. Your content

You keep any rights you have in the structures you draw. You may use generated schemes for your own study, homework and teaching. You give us permission to process your inputs only as needed to provide the Service. See our Privacy Policy.

7. Availability

We aim to keep the Service available but cannot promise it will always be uninterrupted or error-free. We may update, change or discontinue features. If we permanently close the Service, we will cancel active subscriptions so you are not charged again.

8. Liability

To the extent permitted by law, the Service is provided “as is”. We are not liable for indirect or consequential losses, or for losses caused by relying on generated content. Our total liability to you is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits liability that cannot be limited by law, or affects your statutory rights as a consumer.

9. Ending your account

You can stop using the Service at any time. To delete your account, email us at help@chemistryreactionschemes.com. Cancel any active subscription first.

10. Changes to these terms

We may update these terms. If changes are significant, we will notify you on the site or by email before they take effect. Continuing to use the Service afterwards means you accept the updated terms.

11. Law

These terms are governed by the laws of Ireland. If you are a consumer living elsewhere in the EU, you also keep the protection of the mandatory laws of your country.
