Terms of Service

Last updated: 5 July 2026

These Terms are a legally binding agreement between you and CtrlAltRevise ("we", "us", "our") for your use of the CtrlAltRevise platform, website and services (the "Platform"). Please read them with our Privacy Policy, which is incorporated by reference. If you do not agree, do not use the Platform.

  • Provider: CtrlAltRevise, operated by an individual (sole trader) based in the United Kingdom.
  • Contact: ctrlaltrevise@gmail.com (we operate online; please use email for written correspondence).

3. Age restriction

The Platform is for personal, non-commercial educational use.

3.1. If you are under 13:

  • Please do not use the Platform; and
  • Please do not attempt to register for membership or send any personal information about yourself to us, including your name, address, telephone number, or email address.

3.2. Automatic deletion: If it comes to our attention that we have unknowingly gathered information from a person under the age of 13, we will delete that account and information immediately.

3.3. If you are under 18: You confirm that your parent or guardian has reviewed and agreed to these Terms on your behalf. If you make use of the Platform by purchasing any membership or subscription, you confirm that you have obtained permission from the cardholder / payment account holder (who must be 18 years of age or older) to make any such payments.

2. About CtrlAltRevise

We provide independent Computer Science learning materials, practice questions, pseudocode and code exercises, AI-assisted marking and hints, progress tracking, and real-time collaboration tools, to support students preparing for Cambridge IGCSE and International A Level Computer Science. We are not affiliated with, endorsed by, or sponsored by Cambridge. We are a supplementary resource and do not set or mark official examinations.

3. Your account

You agree to provide accurate information and keep it up to date; keep your login details confidential; not share your account; and take responsibility for activity under your account. You may register with an email and password, or with Google or Apple sign-in (which is also governed by that provider's own terms). Tell us at ctrlaltrevise@gmail.com if you suspect unauthorised use. We may refuse registration or suspend an account where information is false or these Terms are breached.

4. Subscriptions, payments and renewals

Some features need a paid subscription ("Premium"). Payments are processed by Stripe; we do not store your card details.

  • Billing and auto-renewal. Subscriptions are billed in advance on a recurring basis (monthly or annually, as you choose) and renew automatically at the end of each period unless cancelled before the renewal date. You authorise us to charge your payment method for each renewal. We will make the price and billing frequency clear before you subscribe.
  • Cancellation. You can cancel any time in your account settings. Cancellation takes effect at the end of the current paid period; you keep Premium access until then.
  • Price changes. We will give at least 30 days' notice of any price increase. If you do not accept it, you can cancel before it takes effect.
  • Free features. Some features are free; we may change the scope of free access with reasonable notice.

4.1 Your 14-day right to cancel (cooling-off)

If you are a consumer in the UK, you normally have the right to cancel a purchase within 14 days without giving a reason, under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.

Important — digital content. When you subscribe, you ask us to give you immediate access to the digital service. By doing so, you acknowledge that you lose your 14-day right to cancel once we have started providing the service, to the extent you have used it. If you have not yet accessed any paid content, you can cancel within 14 days for a refund. To cancel within the cooling-off period, contact us at ctrlaltrevise@gmail.com or use the cancellation option in your account.

4.2 Refunds

Except for the cooling-off right above, and except where the law (including consumer law for faulty or not-as-described digital content under the Consumer Rights Act 2015) requires otherwise, fees are non-refundable and we do not refund unused portions of a paid period. Nothing here removes your statutory rights.

4.3 Trial and Free Access Abuse

You must not create, use, or control multiple accounts to avoid free access limits, trial restrictions, subscription fees, or other payment requirements. Attempts to circumvent these limits may be treated as abuse or fraud and may result in refusal of service, suspension or termination of accounts, loss of promotional access, or other reasonable action permitted by law.

Where parent features are available, a student may explicitly connect a separate parent account to limited progress information. The parent does not control or sign in to the student account, and either side may revoke the connection. These consent-based connections must not be used to evade access limits or payment obligations.

5. Acceptable use

You must use the Platform lawfully and respectfully. You must not:

  • break any law or infringe anyone's rights;
  • share your account or let anyone else use it;
  • copy, scrape, resell, or make derivative works from Platform content without our written consent;
  • use bots, scrapers or scripts to extract data;
  • interfere with or circumvent security or access controls, or attempt unauthorised access;
  • impersonate anyone or misrepresent your affiliation;
  • upload or transmit malware.

5.1 Collaboration and content conduct

The Platform includes real-time collaboration where you can work with others (including guests who join by link) on shared documents, code, and a chat/activity stream. When using collaboration and any feature where others can see what you submit, you must not post, share or transmit content that is:

  • illegal, or that encourages or facilitates illegal acts;
  • harmful to or abusive of others, including bullying, harassment, threats, or hate;
  • sexual content involving minors, or any content that exploits, endangers or sexualises children — this is strictly prohibited and may be reported to the authorities;
  • pornographic, grossly offensive, or designed to cause distress;
  • false impersonation, or someone else's private information; or
  • in breach of anyone's intellectual property or privacy rights.

Be considerate of other participants, who may be children.

5.2 Reporting and takedown (online safety)

We want the Platform to be safe, including for younger users, consistent with the UK's online-safety regime. If you encounter content or behaviour that breaches these Terms — especially anything harmful to a child — report it to ctrlaltrevise@gmail.com. We will review reports and may remove content, suspend sessions, or suspend or terminate accounts, and we will report illegal content to the relevant authorities where appropriate. We may also remove content or limit features to comply with our legal duties. We aim to acknowledge reports promptly and to act on serious safety reports as a priority.

Breach of this Section may result in immediate suspension or termination and, where appropriate, referral to the authorities.

6. AI-assisted marking and hints — disclaimer

The Platform uses an AI service (the Google Gemini API or DeepSeek, depending on our configuration) to provide assisted marking, the lesson tutor, and hints. For some free-text or mock answers, the text of your answer (with the question and mark scheme) is sent to the AI provider to produce a suggested mark and feedback; tutor questions send your question and the lesson text; hint requests do not include your personal data. This is explained in the Privacy Policy.

AI-assisted marks and hints are practice aids only. They are not official Cambridge results and may be inaccurate or incomplete. Do not rely on them as your final grade; always check against the official syllabus and mark scheme. Where a question supports it, you can ask for human review of an AI-assisted mark by contacting us.

7. Intellectual property

Our content

Lesson text, explanations, diagrams, question banks, course structure and software are owned by or licensed to CtrlAltRevise and protected by law. We grant you a limited, non-exclusive, non-transferable, revocable licence to use Platform content for your own personal study while your account is active. No redistribution, commercial use or sublicensing.

Cambridge materials

Cambridge examination papers, syllabuses and mark schemes remain the property of Cambridge Assessment International Education. We create original content inspired by published syllabuses and do not reproduce official Cambridge materials without appropriate permission.

Your content

You keep ownership of the pseudocode, answers, code and collaboration content you create ("User Content"). You grant us a non-exclusive, worldwide, royalty-free licence to store, process and display it to operate the Platform and deliver your learning experience (including, for some answers, sending the text to our AI marking provider as described above), and to share it with other participants in a collaboration session you take part in. We will not sell your individual submissions. You are responsible for your User Content and confirm it does not infringe anyone's rights or breach Section 5.

Feedback

If you send us suggestions or feedback, you grant us a royalty-free, perpetual, irrevocable licence to use it without obligation to you.

8. No guarantee of outcomes

We make no promise that using the Platform will produce any particular grade or result. Exam performance depends on many factors outside our control.

9. Availability, disclaimers and liability

The Platform is provided "as is" and "as available". We do not warrant it will be uninterrupted or error-free, and we may modify, suspend or discontinue parts of it.

To the fullest extent permitted by law, we disclaim implied warranties of merchantability, fitness for a particular purpose, accuracy and non-infringement, and we are not liable for indirect, incidental, special or consequential loss, or loss of data, revenue or opportunity. Our total liability for any claim under these Terms will not exceed the greater of (a) what you paid us in the 12 months before the claim or (b) £50.

Your statutory rights. Nothing in these Terms excludes or limits liability for death or personal injury caused by our negligence, for fraud, or any liability that cannot be excluded by law — including your rights as a consumer under the Consumer Rights Act 2015 (for example that digital content must be of satisfactory quality, fit for purpose and as described).

10. Termination

We may suspend or terminate your access if you breach these Terms or for another legitimate reason; on termination your licence to use the Platform ends. You can close your account at any time in your account settings, which deletes your personal data as described in the Privacy Policy and cancels any active subscription. Clauses that should survive termination (intellectual property, disclaimers, liability, governing law) survive.

11. Third-party links

The Platform may link to third-party sites we do not control and are not responsible for. Use them at your own risk and subject to their terms.

12. Changes, governing law and contact

We may update these Terms and will give reasonable notice of material changes on the Platform and, where appropriate, by email. Continued use after changes take effect is acceptance; if you do not accept, stop using the Platform and close your account.

These Terms are governed by the laws of England and Wales, and disputes are subject to the courts of England and Wales — except where mandatory consumer-protection law in your country of residence gives you other rights.
