LeetTracker Extension

LeetTracker is a companion Chrome extension that automatically tracks your LeetCode problem-solving history and syncs it with the LeetTracker Web App(https://leet-tracker-log.vercel.app), all entirely within your browser. Your submission data stays local — just fast, privacy-focused insights into your own progress. What it does: - Automatically detects and records new LeetCode submissions - Passively logs which problems you view and when - Derives solve time based on visits before submissions - Enriches your submission data with runtime, memory, code, snapshot history, run history, and problem descriptions - Stores everything locally in your browser (via Chrome's storage.local and IndexedDB) - Makes data available to the LeetTracker web app (which also stores it locally) - Shows helpful notifications for sync status, sign-in requirements, and first-time setup How it works: - This extension runs in the background when you're browsing leetcode.com - It passively observes submission events and visited problems - On first use, it will retroactively fetch your full LeetCode submission history - Recent submissions (last 90 days) are enriched immediately; older submissions are queued for gradual enrichment - Synced data is then made accessible to the companion web app at https://leet-tracker-log.vercel.app 🔐 Privacy-focused design: - Submission data never leaves your browser — stored entirely locally - Uses privacy-focused analytics (PostHog) to track extension usage and errors for debugging - Analytics data includes: LeetCode username/ID, usage events, performance metrics, and error reports - No submission code, solutions, or problem content is sent to analytics - You can opt out of analytics by blocking us.i.posthog.com in Chrome's extension settings - See full Privacy Policy at: https://github.com/dmiska25/leet-tracker-extension/blob/main/docs/privacy.html ⚠️ Important Notes: - This extension is not affiliated with or endorsed by LeetCode - Problem content retrieved via the extension is for personal, non-commercial use only - You are responsible for complying with LeetCode's Terms of Service regarding content usage - Analytics help us improve the extension; see Privacy Policy for opt-out instructions Required Permissions: - Access to leetcode.com to read your submission and problem history - Access to leet-tracker-log.vercel.app to inject sync code for the companion web app - Access to us.i.posthog.com for privacy-focused usage analytics - Access to chrome.storage to persist your data locally LeetTracker works silently in the background with occasional helpful notifications to help you understand your progress over time.
