Privacy Policy

Last updated: June 18, 2026

LeetQuant (“we”, “us”) operates www.leetquant.tech (the “Service”), a quant-interview practice platform. This policy explains what we collect, why, and your choices.

Information we collect

  • Account information. When you sign in with Google, we receive your name, email address and profile picture from your Google account. We never receive your Google password.
  • Practice data. The problems you solve, your spaced-repetition review schedule, attempts, recall grades and any notes you save.
  • Usage data. Basic analytics about how the Service is used (pages visited, device and browser type), collected via Google Analytics.

How we use it

To provide and operate the Service — to authenticate you, save your progress and sync it across your devices — and to understand and improve how the Service is used. We do not sell your personal data.

Who we share it with

We share data only with the service providers that help us run LeetQuant, who process it on our behalf:

  • Supabase — authentication and database (stores your account and progress).
  • Vercel — hosting and delivery.
  • Google — sign-in (OAuth) and Google Analytics.

Cookies

We use a session cookie to keep you signed in, and analytics cookies (Google Analytics) to measure usage.

Data retention & your choices

We keep your data while your account is active. You can request access to, or deletion of, your data at any time by emailing us — we will remove your account and the progress associated with it.

Children

The Service is not directed to children under 16, and we do not knowingly collect their personal data.

Changes

We may update this policy from time to time; we will revise the “Last updated” date above when we do.
