Terms of Service

QuantQns is a sole proprietorship based in Singapore. In these terms, "we" and "us" mean the operator of this site, and "you" means the person using it.

You can reach us at figolee2127@gmail.com.

We sell a subscription to an online bank of quantitative-finance interview questions and worked solutions.

The subscription renews automatically at the end of each billing period until you cancel. You may cancel at any time; access then continues to the end of the period you have already paid for, and you are not charged again.

This is a digital service delivered entirely through this website. Nothing is shipped and there is no physical product.

Questions and solutions are provided in English only. The site interface is available in English and Chinese, but the question content is not translated.

You must be at least 16 years old, or have the consent of a parent or guardian, to subscribe.

Accounts are personal and individual. You are responsible for activity under your account, and for keeping your sign-in email secure. We use passwordless sign-in (magic link and Google), so we never hold a password for you.

Current prices are $29 per month, or $243.60 per year — 30% off the $348 that twelve monthly payments would cost. Prices are displayed and charged in USD; your bank may apply its own conversion rate or fees.

Payments are processed by Stripe. We do not receive or store your full card details. Access begins as soon as your first payment is confirmed and renews on the cycle you chose.

We may change prices. Any change is emailed to you at least 30 days in advance and applies only to renewals after that notice — never to a payment already taken. If you do not accept a new price, cancel before it takes effect.

You can cancel at any time from your account page, without contacting us. Cancellation takes effect at the end of the current billing period.

Refunds are governed by our Refund Policy, which forms part of these terms.

You may use the content to prepare for your own interviews. You may not:

• share, resell, republish, or redistribute any premium question or solution;
• share your account or sign-in link with anyone else;
• scrape, crawl, bulk-download, or systematically copy the content, whether manually or by automated means;
• use the content to build, train, or populate a competing question bank, dataset, or model;
• circumvent or attempt to circumvent access controls, rate limits, or watermarking.

We rate-limit access, log premium content views, and embed an identifier of the viewing account in every premium solution. If content traceable to your account is found published elsewhere, or if your usage pattern indicates bulk extraction, we may suspend or terminate your access without a refund.

All content on this site is either written by us or licensed to us, and remains the property of its respective owner. Your subscription grants you a personal, non-exclusive, non-transferable licence to view the content while the subscription is active. No other rights are granted.

Company names appearing on questions are used descriptively, to indicate where a question has been reported. QuantQns is an independent study resource and is not affiliated with, endorsed by, or sponsored by any firm named on this site.

We work hard to keep questions and solutions correct, but we do not warrant that the content is free of errors, or that any question will appear in an interview you sit.

Subscribing does not guarantee an interview, an offer, or a job of any kind. Nothing on this site is financial, investment, career, or legal advice.

We aim to keep the site available continuously but do not guarantee uninterrupted access. Maintenance, third-party outages, and network conditions may cause downtime. If an outage materially prevents you from using the service for an extended period, email us and we will extend your subscription.

To the extent permitted by law, our total liability to you for any claim relating to the site or your subscription is limited to the amount you paid us in the twelve months before the claim arose.

We are not liable for indirect or consequential loss, including lost opportunities, lost offers, or lost income. Nothing in these terms limits liability that cannot be limited by law.

We may suspend or terminate access if you breach these terms, in particular the acceptable-use clause. Where a breach is serious — sharing, reselling, or bulk-extracting content — no refund is due.

You may stop using the site at any time and may request deletion of your account.

We may update these terms. The revision date at the top of this page always reflects the current version. Material changes are emailed to active subscribers. Changes do not apply retroactively.

These terms are governed by the laws of Singapore, and the courts of Singapore have exclusive jurisdiction, without affecting any mandatory consumer protection you have where you live.

These terms are published in English and Chinese. The Chinese version is provided for convenience; if the two versions conflict, the English version governs.
