Analyze your Codeforces performance — solve time, failure rates, rating changes, and errors by division and time range.

Features 1. Contest-wise average and median solve time (A, B, C…). 2. High WA% analysis by contest and overall, with per-problem breakdown. 3. Filter performance by time period (last month, 3 months, year, etc.). 4. Toggle modes: Total / Rated / Unrated. 5. Compact UI below the profile. 6. Dynamic background matching the page theme. How it works: • Runs client-side as a content script on Codeforces profile pages. • Uses Codeforces public APIs (user.status + contest.list + user.rating) and only reads profile/submission data. • No personal data is uploaded by default. See the privacy policy below for full details. Install and open any Codeforces user profile (https://codeforces.com/profile/<handle>) — the compact card will appear below the profile box. What’s New 1. Added time-based filters to analyze performance over different periods. 2. Improved UI with dynamic background. 3. Minor fixes and improvements.
