LeetCode Map does not collect, store, or transmit any personal data.
What the extension does:
- Reads the current LeetCode problem URL to identify which problem you're viewing
- Sends the problem slug (e.g. "two-sum") to our API to fetch similar problems
- Stores cached problem data and your solved-problem list locally in your browser (chrome.storage.local)
What we do NOT do:
- No user accounts or login
- No analytics or tracking
- No cookies
- No data shared with third parties
- No personal information collected
All data stays in your browser. The only network request is fetching problem similarity data from our server, which does not log or store user identifiers.
