Privacy Policy

1. Introduction

Welcome to LC Tracker ("we", "our", or "us"). We are committed to protecting your personal information and your right to privacy. This Privacy Policy explains how we collect, use, and share information about you when you use our website at https://lc-tracker.app (the "Service"), a LeetCode progress tracking and spaced-repetition review application.

2. Information We Collect

Google Account Information: When you sign in using Google OAuth, we receive your basic Google profile information — specifically your name, email address, and Google account ID. This is the only data we receive from Google and it is used solely to create and identify your account. We do not access your Gmail, Google Drive, Google Contacts, or any other Google service data.

Usage Data: We store the LeetCode problems you track, your solve history, spaced-repetition review progress, mock interview logs, and user settings. This data is stored in our database to persist your progress across sessions and devices. Notes you write may contain sensitive content — export backups carefully.

3. How We Use Your Information

We use the information we collect solely to provide and improve the Service:

• To authenticate your identity and manage your account via Google Sign-In.
• To store and sync your problem-solving progress and review schedule.
• To display your analytics, streaks, and performance history within the app.

We do not use your Google account data for advertising, profiling, or any purpose beyond operating the Service.

4. Google API Data Disclosure

LC Tracker's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

5. Sharing Your Information

We do not sell, trade, or rent your personal information. We share data only with Clerk (authentication) and Supabase (database hosting) as required to operate the Service.

6. Revoking Access

You can revoke LC Tracker's access to your Google account at any time via your Google Account permissions page. You may also request account deletion by contacting us.

7. Data Retention & Deletion

Progress data is retained while your account is active. You can export a JSON backup from Settings at any time. Upon account deletion we remove associated progress data from our systems.

8. Security

We use industry-standard protections appropriate for a study tracker. No method of transmission over the Internet is 100% secure.
