Terms of use

Last updated 4 November 2026

These terms are the agreement between you and Draft. Please read them with the privacy notice and the cookie policy. By creating an account you accept them.

1. Who provides Draft

Draft is provided by Yasir Widatalla. Contact: [email protected].

2. What Draft is, and is not

Draft is an educational tool that helps healthcare and clinical-research students plan a quantitative study: a research question, a design, a statistical plan and R code to carry it out.

• It is not a substitute for a supervisor, a statistician, ethics approval or your institution’s governance process. Every plan it writes needs checking and sign-off by a qualified person before it is used.
• It is not clinical advice, and is not for use in the care of any patient.
• Answers from the Ask box are written by an AI model and can be wrong. Check them.

3. Your account

• You must be 18 or over.
• Use your own email address and keep access to it private: anyone who can read your email can sign in as you.
• Tell [email protected] straight away if you think someone else has used your account.

4. Using Draft properly

You must not:

• enter patient-identifiable information, real participant data, or anything you are not allowed to share;
• try to get into parts of Draft that are not meant for you, test its security without permission, or disrupt it;
• copy the tool or its teaching material in bulk, use automated means to extract it, or resell access;
• share your account with other people.

5. Subscriptions and payment

• Plans: Student, £12 a month (for an address at a university or college), and Professional, £25 a month. Prices include any VAT that applies.
• Payment is taken by Stripe. A subscription renews every month until you cancel it.
• If a price changes, you will be told at least 30 days before your next payment, and can cancel before then.
• Access may also come free, or through your institution’s plan, on the terms you were given.

6. Cancelling, and changing your mind

• Cancel at any time from inside Draft: cancel my subscription opens the question, and one press of Yes, cancel stops it renewing. You keep access until the end of the month you have paid for, and you will not be charged again.
• Changing your mind: you have 14 days from when you first subscribe to cancel and get your money back. Because Draft starts as soon as you subscribe, if you cancel within those 14 days you may be charged for the days you had access, and refunded the rest. To use this right, write to [email protected] within the 14 days.
• Apart from that, payments for a month already started are not refunded, unless the service was faulty (see section 8).

7. Your work, and Draft’s

What you write in Draft is yours. You allow Draft to store and process it only to provide the service to you. The tool, its teaching material, design and name belong to Draft’s owner; you may use them for your own study and teaching through the service, and may keep and use the plans, documents and R code it makes for you.

8. If something goes wrong

• Draft is provided with reasonable care and skill. Your legal rights under the Consumer Rights Act 2015 are not affected: if the service is faulty, you are entitled to have it put right or, if that cannot be done, to some money back.
• Draft may change, improve or occasionally be unavailable. If a change takes away something important that you pay for, you will be told and may cancel.
• Draft is not responsible for losses that could not have been foreseen, or for the results of a study, assessment or decision based on a plan that was not checked as section 2 requires.
• Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for anything else the law does not allow to be limited.

9. Ending your account

You can delete your account at any time from your account page. Deleting it does not cancel a subscription, so cancel first. Draft may suspend or close an account that seriously or repeatedly breaks these terms, and will warn you first unless the law or an urgent risk prevents it.

10. Changes to these terms

If these terms change in a way that matters, you will be told at least 30 days before. If you do not agree, you can stop using Draft and cancel before the change applies.

11. Complaints and the law

Please write to [email protected] with any complaint; you will get a reply within 14 days. These terms are governed by the law of England and Wales. If you live in Scotland or Northern Ireland you can also bring a claim in the courts there.
