Terms & Conditions

1. Your agreement with us

QuantSolve is provided by Edward Fritzell, trading as QuantSolve ("we", "us" or "our"). By accessing or continuing to use QuantSolve, you agree to these Terms and contract with Edward Fritzell for use of the service. Paddle acts as reseller for paid orders as described below. If you do not agree, do not use the service.

You must be of legal age to enter a binding agreement in your jurisdiction, or have the necessary permission from a parent or guardian. If you use QuantSolve for an organisation, you confirm that you have authority to bind it.

2. The service and your account

QuantSolve provides quantitative finance interview preparation, including practice questions, solutions, lessons, mental math drills, deterministic question variations, job links and educational tools. Free and Pro access differ as described on the Pricing page. We do not guarantee employment, interview success or a particular learning outcome.

Provide accurate account information and keep it up to date. Keep your login credentials confidential and do not share or resell your account. You are responsible for activity under your account; report suspected unauthorised access promptly.

3. Acceptable use

You must not:

• Use the service unlawfully, for fraud, spam, harassment, or content that infringes another person's intellectual property or privacy rights.
• Introduce malware, probe or bypass security or access controls, scrape the service, disrupt its operation, or attempt to access another user's data.
• Circumvent subscription restrictions or technical limits, reverse engineer the software except where applicable law permits it, or reproduce, redistribute or resell our content without permission.

You must have the necessary rights to any material you submit. You remain responsible for your submissions and how you use the service.

4. Intellectual property

Edward Fritzell retains ownership of QuantSolve and its intellectual property, including software, original questions and solutions, documentation, design and branding. Third-party material remains owned by its respective rights holders. We grant you a limited, non-exclusive, non-transferable licence to use the service for your personal or authorised internal learning within your selected plan.

You retain rights to your own submissions. You give us only the permission needed to host, process and display them to provide the service. If you believe content infringes your rights, contact us through the billing support route described below, identifying the material and the basis of your claim. We may remove or restrict reported content and suspend accounts for repeated or serious infringement.

5. Payments, renewals and Paddle

Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns.

Paid purchases are also subject to Paddle's Buyer Terms, which govern payment, billing, taxes, subscription cancellation and refund mechanics. Pro is offered at US$15 per month, US$39 every three months or US$99 per year. Your selected billing period, price and applicable taxes are shown at checkout.

Subscriptions renew automatically for the selected period unless cancelled before renewal. Manage or cancel through the subscription controls on your profile or at paddle.net. Cancellation stops future renewals; access normally continues until the end of the paid period. Plan changes and any billing adjustments follow the options and amounts Paddle presents before confirmation. See our Refund Policy for refunds.

6. Availability and educational limitations

We aim to keep QuantSolve available, but do not guarantee uninterrupted, secure or error-free performance. Maintenance, outages, updates and corrections may affect availability or content. To the extent permitted by law, the service is provided "as is" and "as available", without implied warranties of merchantability or fitness for a particular purpose.

Finance questions, formulas, job information and the Greeks and Black–Scholes tools are for general educational purposes only. They are not financial, investment, legal or tax advice, or recommendations to buy or sell. Verify important information independently; your decisions remain your responsibility.

7. Suspension and termination

We may restrict, suspend or terminate access for material breach of these Terms, non-payment, security or fraud risks, or repeated or serious policy violations. Where appropriate and safe, we will notify you and allow you to address the issue. You may stop using the service at any time; cancelling an account does not replace cancelling a paid subscription through Paddle.

After access ends, your right to use restricted content ends. Personal data is retained or deleted under our Privacy Notice; you may exercise applicable data rights. Termination does not remove statutory refund rights or other rights that cannot legally be excluded.

8. Liability and your legal rights

To the extent permitted by law, we are not liable for indirect or consequential losses, including lost profits, missed opportunities or loss of data arising from use of the service. Nothing in these Terms limits liability for fraud, death or personal injury caused by negligence, or any liability or consumer protection that cannot lawfully be excluded. Mandatory rights available under the law applicable to you remain unaffected.

9. Changes and contact

We may update these Terms as the service changes or to meet legal requirements. We will publish the revised date and provide appropriate notice of material changes. Changes do not retrospectively remove rights relating to earlier purchases.
