Terms, Privacy & Refunds

Terms of Service

QuantInterview is a quant-interview preparation platform: a question bank with solutions, hints, progress tracking, and timed mock interviews. By creating an account or purchasing access you agree to these terms.

Your account

• You need an account (with a real email you control) to track progress or purchase access.
• Accounts are personal. Don't share login details or resell access.

Subscriptions and purchases

• Monthly (£20/month) renews automatically each month until you cancel. Cancel anytime from the billing portal (Pricing → "Manage / cancel my subscription"); you keep access until the end of the paid period.
• Lifetime (£150 one-off) grants access for as long as QuantInterview operates, including future question additions.
• Payments are processed by Stripe; we never see or store your card details.
• Prices may change; changes never affect a lifetime purchase already made, and subscription price changes are notified before they apply.

Acceptable use

• Content (questions, solutions, hints) is for your personal interview preparation. Don't scrape, bulk-download, republish, or redistribute it.
• We may suspend accounts that abuse the service (scraping, sharing, payment fraud). If we suspend a paid account for abuse, no refund is owed.

The honest disclaimers

• Questions and solutions are curated carefully but provided "as is". We don't guarantee they're error-free, and practising here doesn't guarantee any interview outcome.
• Our liability to you is limited to the amount you paid us in the 12 months before a claim.
• We may update these terms; material changes will be announced on the site. Continued use after changes means acceptance.

Refund Policy

If something isn't right with a purchase, email contact@quantinterview.io within 14 days of the payment and we'll work with you to make it right, including a refund where appropriate. Because access is digital and granted immediately, we may decline or reduce a refund where the service has been substantially used in that time, or where access has been abused (for example scraping, bulk-downloading, or sharing). Renewal payments can be refunded if you ask within 14 days of the renewal and haven't substantially used the service since. This does not affect any statutory rights you may have.

Privacy Policy

Short version: we collect the minimum needed to run the product, we don't run ads or trackers, and we never sell your data.

What we store

• Account: your email address and a bcrypt hash of your password (we cannot see the password itself).
• Progress: which questions you've solved/bookmarked and your private notes, so they sync across devices.
• Billing: your Stripe customer id and plan. Card details live with Stripe only.

Who processes it

• Railway hosts our backend and database.
• GitHub Pages serves the website.
• Resend sends transactional email (verification, password reset). We don't send marketing email.
• Stripe handles payments.

Cookies and local storage

No advertising or analytics cookies. We use your browser's local storage for your session token, a local copy of your progress, and your light/dark preference, and nothing more.

Your rights

Email contact@quantinterview.io to export or delete your account and all associated data, and we'll do it within 30 days. You can also delete your progress yourself from your profile page in the app ("Reset all progress").
