Terms of service

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

We provide independent Computer Science learning materials, practice questions, pseudocode and code exercises, 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.

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.

Some features need a paid subscription ("Premium"). For purchases through Paddle, Paddle is the Merchant of Record and handles payment, applicable taxes and receipts. Existing Stripe subscriptions continue to be billed through 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 stop a confirmed subscription's renewal in Plan & payments. 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.

Invite two new, distinct student accounts using your personal referral link to earn one free month, once per referring account. Both you and the invited students must verify your email addresses and finish setup. The invited students do not need to pay. Self-referrals, email aliases and accounts created to evade the offer limits do not qualify.

Monthly subscribers receive one month of their own plan price as billing credit. Annual subscribers receive one-twelfth of their annual plan price as credit toward a future invoice. Eligible Starter accounts receive 30 days of access to their selected course. A reward waits if there is no safely eligible course or billing target, and may require reconciliation after a payment-service error. Rewards have no cash value. Earlier referrals under the paid-signup offer keep their original terms.

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.

AI-assisted marking, hints and tutoring are currently unavailable. Do not purchase a subscription on the assumption that these features are included or will become available on a particular date. Before enabling them, we will explain their availability and how any answers, code or questions are processed. This is explained in the Privacy Policy.

If made available, 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.

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

We provide the service with reasonable care and skill. We cannot promise uninterrupted access, but will take reasonable steps to resolve faults and communicate significant changes affecting paid access.

If we breach these Terms, we are responsible for loss or damage that is a foreseeable result of that breach or our failure to use reasonable care and skill. We do not limit your rights or remedies for faulty or misdescribed digital content or services. The Platform is for personal educational use; we do not accept liability for business losses.

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).

We may temporarily suspend or indefinitely ban your access if you breach these Terms, create a safety or fraud risk, or for another legitimate reason. We will show the reason for the decision and, for a temporary suspension, its planned end date. You may appeal from the restricted-account screen; the appeal is linked to the exact decision so another administrator can review the context and your response. We may restore access early or after review, and temporary suspensions are restored automatically when their stated period ends.

Restriction does not delete your learning or account data. It also does not automatically cancel an active subscription: the restricted-account screen keeps a billing-management control available so you can review or cancel billing, and you can raise billing concerns in your appeal. You can download your data or close your account from that screen at any time; closing the account deletes your personal data as described in the Privacy Policy and cancels any active subscription. On termination your licence to use the Platform ends. Clauses that should survive termination (intellectual property, disclaimers, liability, governing law) survive.

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.

We may update these Terms and will give reasonable notice of material changes on the Platform and, where appropriate, by email. We record the version you accept and when you accept it. When renewed acceptance is required, we ask you to review the Terms before continuing to learning features. You can still manage your account and subscriptions, contact support, export your data or delete your account without accepting the new Terms. Earlier use is not recorded as acceptance of a later version.

These Terms are governed by Egyptian law, subject to the mandatory consumer protections that apply to you. Nothing in them excludes rights that cannot lawfully be excluded, or prevents you from bringing a claim before a court that has jurisdiction under applicable law. Operating from Egypt does not remove applicable protections for consumers in other countries.
