LeetTracker Extension

Companion Chrome extension for LeetTracker, a LeetCode progress tracker.

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. No server-side tracking, no cloud sync — just fast, local 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) - Makes data available to the LeetTracker web app (which also stores it locally) 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 — this may take several minutes if you’ve solved many problems - Synced data is then made accessible to the companion web app at https://leet-tracker-log.vercel.app 🔐 Privacy-first design: - No data is ever sent to an external server - All submission history, metadata, and enrichment are stored locally - No telemetry, no cookies beyond LeetCode session, no tracking of your activity outside of leetcode.com ⚠️ 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 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 chrome.storage to persist your data locally No popups, no manual input — LeetTracker works silently in the background to help you understand your progress over time.
