💡 Why Should You Install It?
Standard Codeforces profiles only show basic stats. CF Analytics Pro Max helps you actually understand your data. By visualizing your performance, you can easily spot bottlenecks (e.g., "I spend too many tries on DP problems" or "My execution time spikes on 1800+ rating graph problems"), making your training much more efficient. Plus, the seamless long-image export makes sharing your milestones effortless.

🔒 Privacy & Security:
All data processing happens locally in your browser. The extension only requests public data using the official Codeforces API (/api/user.status). No personal data is collected or sent to third-party servers.
