Fair terms. No surprises.

§ 01Agreement

These Terms are a contract between you and CertAnvil. CertAnvil is the trading name of Oluwasimisola Oremosu, a sole trader in the United Kingdom. Email support@certanvil.com.

By creating an account, subscribing to a paid plan, or using any part of the CertAnvil website or apps, you agree to these Terms and to our Privacy Policy.

If you don't agree, please don't use CertAnvil. You can stop using it at any time and (if you have an account) delete it from Settings, see § 06.

§ 02Eligibility

To use CertAnvil you must be at least 13 years old. In jurisdictions where the minimum age for digital consent is higher (e.g. 16 in parts of the EU), you must meet that local minimum or have a parent/guardian's permission.

If you're using CertAnvil on behalf of an employer or training provider, you confirm you have authority to bind that organisation to these Terms.

You may not use CertAnvil if you're subject to economic sanctions imposed by the UK, the EU, the United States, or the United Nations that would prevent us from providing services to you.

§ 03Your account

You sign in by requesting a one-time code sent to your email address. Anyone with access to that inbox can sign in as you. Keep your email account secure by enabling two-factor authentication with your email provider.

You're responsible for the activity that happens under your account. If you suspect someone else has accessed your account, sign out from Settings (which invalidates active sessions) and contact support@certanvil.com immediately.

One person, one account. Don't share accounts or sell access. Team licences for bootcamps and training providers will be available separately. Until they ship, contact us if you need bulk access.

CertAnvil works in current versions of the major web browsers and in the CertAnvil iPhone app, and needs an internet connection.

§ 04Subscriptions and pricing

4.1 · Free tier

Free is available without a card, for as long as you like. Each day you get 15 practice questions and 5 review cards on one cert. You also get one Sim Lab run, one Decision Lab set and one Reword Gauntlet run a day, plus the Baseline Diagnostic and Pass Plan for your cert. Your analytics and progress are included. Your daily limits reset at midnight UTC.

Free covers one cert. Once you pick it, you can't switch to another unless you go Pro. Free does not include the Exam Simulator, Sim Lab Exam mode, Decision Lab Exam-style mode, Why-Not, Drill Mistakes, the Guided Lab, or practice sets bigger than 15 questions.

4.2 · Pro tier

Pro opens every cert and takes off the daily limits on questions, review cards, Sim Lab, Decision Lab and the Reword Gauntlet. It also adds the Exam Simulator (a full-length timed practice exam), Exam mode in Sim Lab and Decision Lab, Why-Not, Drill Mistakes, the Guided Lab, practice sets of any size, and a Baseline Diagnostic and Pass Plan for every cert. "No limit" means no limit in normal study use. We may slow or stop automated or abusive use under § 07. Refunds are covered in § 05. Two billing periods are available at checkout:

4.3 · Billing and auto-renewal

Your subscription renews automatically at the end of each month or year until you cancel. By subscribing you authorise the charge to your payment method on each renewal date. We never see your card details. You get an emailed receipt for each payment. After you buy, we also email you a confirmation of your plan, price, renewal terms and what you agreed to. If you're on Yearly, we email you a reminder 7 to 14 days before each renewal, and an earlier one 28 to 35 days before. If you're on Monthly, we email you a reminder 7 to 14 days before a payment, every 6 months.

If a renewal payment fails, it is retried several times over about two weeks. You keep Pro during that time and see a note asking you to update your card. If every retry fails, the subscription is cancelled, Pro ends and your account goes back to Free with your progress kept.

Payments and receipts come from Onelink (see 4.8). Renewal reminders come from us.

Payments are processed by Stripe, which sends your receipts.

4.4 · Launch offer

When Pro went on sale, Yearly was offered at a lower price for the first year: $69, £59 or €69, from until 23:59 UK time on . The offer covers your first year only. When that year ends, your subscription renews at the normal Yearly price ($89, £79 or €89) unless you cancel first, and you get a reminder email before that renewal. The end date is fixed and will not be extended.

In the iPhone app the offer is an App Store introductory offer, which Apple gives only to people new to CertAnvil Pro.

4.5 · Price changes

We may change subscription prices at any time. If we change the price of your specific plan, we'll email you at least 30 days before the change applies to your account. You can cancel before the new price takes effect if you don't want to continue at the new price. Existing annual subscribers are price-locked for the remainder of their current paid year.

4.6 · Currency and tax

In the UK you pay in pounds and in the euro area in euros, always. Elsewhere prices are shown in US dollars (US$ outside the US). Prices include VAT or sales tax where it applies, so the price you see is the price you pay.

Outside the UK and the euro area, checkout may show and charge the price in your local currency, converted by Onelink. The amount on the checkout page is the amount you pay.

Your bank may charge its own fee for a payment in another currency.

4.7 · Purchases in the iPhone app

If you buy Pro in the CertAnvil iPhone app, Apple bills you through your Apple ID under Apple's terms. Apple handles payment, renewal, cancellation and refunds for those purchases. To cancel, use your Apple ID subscription settings at least 24 hours before renewal. Pro belongs to your CertAnvil account wherever you bought it, so it works on the web too. Apple's Standard End User Licence Agreement also applies to the iPhone app.

§ 05Refunds

5.1 · Your 14-day right to cancel

If you buy Pro on the web, you can cancel within 14 days of the day you bought it and get money back. Because you asked for Pro to start straight away, you get back what you paid minus the part that covers the days you had Pro. The 14 days end at 23:59 UK time on the 14th day after the day you bought.

To cancel and get the refund, tell us in any clear way, for example by emailing support@certanvil.com from the email on your account. We then end Pro and refund the unused part. On the web it's quicker: open Billing and choose Cancel now and refund the unused part. Pro ends straight away and the refund is automatic. The refund reaches the payment method you used within 14 days of you telling us, and we charge no fee for it. After each yearly renewal you get another 14 days to do the same, counted from the day it renewed.

5.2 · After 14 days

After the 14 days there are no refunds for the time left on your plan, and you keep Pro until the end of the period you paid for. If something went wrong, email support@certanvil.com from the email on your account and we'll look at it case by case. Your other legal rights, for example if Pro is faulty or not as described, are not affected.

5.3 · iPhone purchases

Refunds for purchases made in the iPhone app are handled by Apple at reportaproblem.apple.com. We can't issue them.

5.5 · If a payment is refunded in full

If your latest web payment is refunded in full, Pro ends straight away and the subscription is cancelled, so it won't renew.

§ 06Cancellation

6.2 · Cancel in the iPhone app

Cancel in your Apple ID subscription settings at least 24 hours before renewal.

6.3 · Delete account

From the cert app → Settings → "Delete my account". Here is what happens:

• When you ask us to delete your account, we stop any subscription billed through Stripe from renewing, straight away. Your account is deleted 7 days later unless you sign back in. Pro ends when the account is deleted. If you sign back in within the 7 days, you can resume Pro from Billing.
• Permanently delete your account email, profile, quiz history, drill mastery, milestones, topology saves, and performance telemetry rows.
• Sign you out and clear local browser cache.

Deleting your account does not refund the time left on your plan. If you're within 14 days of buying and want the unused part back, cancel with a refund first (5.1).

Deleting your account does not cancel a subscription billed by Apple. Cancel it in your Apple ID settings, or Apple keeps charging you.

The deletion cascade is irreversible. Stripe keeps its own billing records under its retention policy (typically 7 years, for tax and chargeback compliance), and we can't delete those.

§ 07Acceptable use

You may:

• Use CertAnvil to prepare for the certifications it supports.
• Share screenshots, your readiness number, and your honest opinion of the product on social media.
• Cite specific question explanations in a study group, as long as you don't republish wholesale chunks of the question bank.

You may not:

• Use the AI question-generation pipeline to produce non-cert content (creative writing, code generation, general-purpose chat).
• Automate access to the AI proxy beyond normal human use, including headless browsers, scripts, or API scraping.
• Bypass the daily-question quota by creating multiple Free accounts.
• Reverse-engineer, decompile, or attempt to extract our prompts, system instructions, or proprietary content.
• Republish or resell the question bank, exemplar bank, or any other CertAnvil content as your own product.
• Use CertAnvil for any unlawful purpose, including reselling access in jurisdictions where we are blocked or sanctioned.
• Submit fraudulent refund claims.

If we believe you're violating these rules, we may suspend or terminate your account, see § 12.

§ 08Intellectual property

CertAnvil's question exemplar bank, retention-concept library, scenario explanations, drill content, and underlying code are owned by us. You get a personal, non-transferable, non-exclusive licence to use them via the product for the duration of your account. You don't get the right to redistribute, resell, or build derivative products from them.

Your data is yours. We do not claim ownership of your quiz history, your saved topologies, or anything else you input. You can export it at any time (Settings → Export Data) and we delete it on request.

The CompTIA exam names (Network+, Security+, N10-009, SY0-701, etc.) are trademarks of CompTIA. CertAnvil is not affiliated with or endorsed by CompTIA. We prepare you for their exams using publicly-documented objectives.

§ 09AI-generated content

The questions, explanations, deep dives, and AI coach responses in CertAnvil are produced by Anthropic's Claude model and run through a 7-layer validation stack (prompt self-check, curated exemplar bank, semantic second-pass, interrogative-stem gate, programmatic validator, regression gate, and Sonnet escalation). That pipeline is there to catch hallucinations and factual errors, but we can't guarantee every output is correct.

Always cross-check answers against the official CompTIA objectives and reputable resources (Professor Messer, Jason Dion's books, the CompTIA Exam Objectives PDF). If you spot an error, please report it via the "Report this question" button in the app. Your reports feed directly back into the validation pipeline.

We are not responsible for exam outcomes that depend on relying solely on AI-generated content as your only source of preparation.

§ 10Service availability

We aim for 99.5% uptime on a rolling 30-day basis. Realistically you should expect occasional downtime for maintenance, dependency outages (Supabase, Stripe, Vercel, Anthropic), or genuine bugs.

CertAnvil is provided "as is" and "as available". We don't guarantee that the service will be uninterrupted, error-free, or that any specific feature will be available at any specific time. We may add, modify, or remove features at our discretion, though we'll try to give notice for material changes that affect Pro subscribers.

§ 11Limitation of liability

To the maximum extent permitted by applicable law:

• CertAnvil's total liability to you for any claim arising out of or related to these Terms or the service is limited to the amount you paid us in the 12 months before the claim arose. For Free users, that maximum is £0.
• We are not liable for indirect, incidental, consequential, special, or punitive damages. That includes lost profits, lost study time, exam fees you had to re-pay, or career outcomes affected by an exam result.
• We are not liable for the actions of third-party sub-processors (Stripe, Anthropic, Supabase, etc.), though we'll cooperate with you to resolve issues caused by them.

Nothing in these Terms limits liability for death or personal injury caused by our negligence, fraud, or any other liability that cannot be limited under applicable law (notably your statutory rights as a consumer under UK or EU law).

§ 12Termination by us

We may suspend or terminate your account if you:

• Violate the Acceptable Use rules in § 07.
• Submit fraudulent refund claims, chargebacks for legitimate charges, or fake billing disputes.
• Use the service in a way that creates legal liability for us (e.g. operating from a sanctioned jurisdiction).

If we terminate your account for a violation of these Terms, you forfeit any unused portion of your subscription and we are not obligated to refund. If we terminate your account for any other reason (e.g. we wind down the service entirely), we'll refund the unused portion of your most recent payment on a pro-rata basis.

§ 13Disputes and governing law

13.1 · Try to resolve directly first

If you have a complaint, please email support@certanvil.com with the details. We respond to most complaints within 7 days and try to resolve them quickly and fairly.

13.2 · Governing law

These Terms are governed by the laws of England and Wales. Any legal dispute will be brought in the courts of England and Wales. The one exception: if you're a consumer in the UK, EU, or another jurisdiction with mandatory local consumer-protection law, you may also bring claims in your local courts under your local law where that law requires it.

13.3 · No class actions

To the maximum extent permitted by applicable law, you agree to resolve disputes individually rather than as part of a class action or representative proceeding. (This clause does not apply if it would conflict with mandatory consumer law in your jurisdiction.)

§ 14Changes to these terms

We may update these Terms from time to time. For material changes (pricing, refund policy, acceptable use rules, governing law) we'll notify subscribers by email at least 14 days before they take effect. For minor edits (typos, link fixes, clarifications that don't change substance) we may publish the updated version without notice. The "Last updated" date at the top of this page reflects the most recent material change.

This is v1.2. Versions so far:

• v1.2 (5 November 2026): Pro goes on sale: prices in your currency with tax included, the launch offer, renewal reminders, who takes web payments, iPhone purchases through Apple, your 14-day right to cancel with an automatic refund, deletion stops renewal, and one contact address. The version you accepted stays at certanvil.com/legal/terms-v1.2.
• v1.1 (28 October 2026): you now sign in with a one-time code sent to your email. Your rights and obligations haven't changed.
