Privacy Policy

What we collect

LeetRecall only stores what it needs to run your spaced-repetition practice:

• Account identity. You sign in with Google, GitHub, or Discord. Through that sign-in we receive your email address and basic profile information from the provider you choose. LeetRecall does not create or store passwords.
• Practice history. Your reviews (pass/missed ratings and the time you spent), each card's scheduling state, and your per-problem progress. This is what powers your queue and analytics.
• Settings. Your preferences, such as your daily card target, timer mode, and catch-up option.
• Bug reports. If you send a bug report, we store the description you write, the page you were on, and your browser's user-agent string so we can reproduce the problem.

How we use it

We use your data to schedule your reviews, build your daily queue, show you category analytics, keep you signed in, and fix issues you report. We do not use it for advertising, and we do not sell or rent it to anyone.

Where it is stored

Your account and practice data live in Supabase, which provides our database and authentication. Row-level security scopes your records to your account, so other users cannot read your data. When you choose to sign in with Google, GitHub, or Discord, that provider handles the sign-in and shares your email and basic profile with us. The site itself is hosted on Vercel, which processes requests and standard server logs. Beyond these, no other third parties are involved in running LeetRecall.

Cookies and tracking

LeetRecall uses session cookies from Supabase to keep you signed in. That is it. We do not run third-party analytics, advertising pixels, or cross-site tracking scripts.

Retention and deleting your account

We keep your data for as long as your account is active. There is no self-serve delete button yet. To delete your account and its associated practice data, email support@leetrecall.com from the address you use to sign in, and we will remove it. If you have a specific question about the data tied to your account, reach out to the same address.

Children

LeetRecall is intended for a general audience preparing for technical interviews and is not directed to children under 13. We do not knowingly collect data from children under 13.

Changes to this policy

We may update this policy as LeetRecall changes. When we do, we will update the effective date at the top of this page, and for material changes we will make the update visible in the app. Continuing to use LeetRecall after a change means you accept the updated policy.
