Terms of use

Last updated 13 November 2026

These terms are the agreement between you and William Tunna, a sole trader trading as ATPL Buddy (“we”, “us”), for using ATPL Buddy. You accept them when you create an account. Please read them; they're short. Our privacy notice explains how we handle your data.

1. What ATPL Buddy is, and isn't

ATPL Buddy is a planning and revision aid for UK ATPL(A) theory students. It helps you organise study time, track mock scores, look up formulas and understand your Knowledge Deficiency Reports.

• It is not an approved training course, and it doesn't replace your Approved Training Organisation, its syllabus or its materials.
• It is not affiliated with or endorsed by the UK Civil Aviation Authority. Learning objective references come from the CAA's published syllabus.
• The readiness lights and study plan are estimates based on what you enter. They can't guarantee you'll pass an exam.
• We work hard to keep the formulas, worked examples and guides accurate, but they are study aids. Where they differ from your ATO's material or the CAA syllabus, follow those. Please tell us about mistakes at privacy@will.aero.
• Nothing in ATPL Buddy is for use in real flight planning or operating an aircraft.

2. Your account

• You must be 16 or over and give a real email address you control.
• Your account is for you alone. Don't share it or let others sign in as you.
• You're responsible for what you enter. Don't upload anything that isn't yours to share.

3. Fair use

Please don't:

• try to get into other people's accounts or data, or test our security without written permission;
• overload, scrape, copy or resell the service or its content (formula cards, guides, diagrams);
• use ATPL Buddy to break the law.

If you do, we may suspend or close your account. Unless it would be unlawful or put others at risk, we'll tell you why first and give you a chance to respond. If we close a paid account for a reason that isn't your fault, we'll refund the unused part of what you paid.

4. Free and paid plans

The beta. ATPL Buddy is in beta. It's free, things may change or break, and features may come and go while we learn what helps. Please tell us when something goes wrong using “Send feedback”.

Founding members. We'll give beta testers who use ATPL Buddy regularly and help us improve it free access to the paid plan for as long as we run ATPL Buddy, at no cost and with nothing to renew. We decide who qualifies, based on how often you use it and the feedback you give, and we'll tell you if you've been chosen. Founding member access is personal to your account and can be removed if you break these terms.

During the beta, ATPL Buddy is free. When paid plans start, we'll show you the full price (including VAT if it applies), what it includes, and whether it's a one-off payment or a subscription before you pay. Nothing is charged without you choosing a paid plan.

• Subscriptions renew automatically at the end of each period until you cancel. We'll show the renewal date and price before you buy, remind you before renewals as the law requires, and you can cancel online in Settings as easily as you signed up. Cancelling stops the next renewal; you keep access until the end of the period you've paid for.
• One-off purchases give access for the period described when you buy, for as long as we run ATPL Buddy.
• If we change the price of a subscription, we'll tell you at least 30 days before it applies to you, and you can cancel before then.

5. Your right to cancel

If you buy as a consumer, you normally have 14 days from purchase to cancel and get a full refund. Because ATPL Buddy is digital and starts straight away, at checkout we'll ask you to agree to immediate access. If you agree and then cancel within the 14 days, we'll still refund you, minus a fair amount for the time you've already had access. To cancel, email privacy@will.aero or use Settings.

6. If something goes wrong

We'll provide ATPL Buddy with reasonable care and skill. As a consumer you have legal rights, and nothing in these terms affects them. Citizens Advice can explain them.

• We aim to keep ATPL Buddy available, but we can't promise it will never be down, for example during maintenance or a provider outage.
• We may change or improve features. If we remove something important from a paid plan, you can cancel and get a refund for the unused part.
• Keep your own records of anything that really matters (such as official exam results). You can export your data at any time in Settings.

We're responsible for loss or damage you suffer that is a foreseeable result of us breaking these terms or failing to use reasonable care. We aren't responsible for losses that weren't foreseeable, or for business losses: ATPL Buddy is for personal study. We don't limit our liability where it would be unlawful to, including for death or personal injury caused by our negligence, or for fraud.

7. Exam feedback you post

Exam feedback is shared with every signed-in ATPL Buddy user, anonymously unless you choose to show your first name. When you post, please:

• describe your own honest experience;
• describe topics, not exact questions. Don't copy or reconstruct real exam questions or answers: CAA exam rules forbid sharing exam content, and breaking them can affect your exam results;
• don't post anything offensive, abusive, discriminatory, unlawful or that identifies another person, and don't advertise.

You keep ownership of what you post, and you let us show it to other users within ATPL Buddy for as long as it's up. You can edit or delete it at any time. Anyone can report a post; posts reported by several users are hidden until we review them, and we may remove posts that break these rules. To complain about a post or a moderation decision, email privacy@will.aero.

8. Content

The data you enter is yours. You let us store and process it only to provide ATPL Buddy to you, as set out in the privacy notice. The app, formula cards, diagrams and guides belong to us or our licensors; you may use them for your own study.

9. Ending the agreement

You can stop using ATPL Buddy and delete your account at any time in Settings. If we ever close ATPL Buddy, we'll give you at least 30 days' notice where we can, time to export your data, and a refund for any unused paid period.

10. Changes to these terms

We may update these terms, for example when paid plans start or the law changes. We'll tell you in the app and ask you to accept important changes before they apply to you. If you don't accept them, you can close your account and get a refund for any unused paid period.

11. Complaints and the law

If you have a problem, email privacy@will.aero and we'll try to sort it out quickly. 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 your local courts, and your local consumer law still protects you.
