What we collect

Personal data

How It Works

Automatic hooks, secure submission, and real-time analytics.

After register or login, Modu Arena installs hooks automatically for tools detected in your environment.

Whenever a coding session ends, the hook sends anonymized metrics to the Modu Arena API.

Your data appears on your dashboard and is reflected in community leaderboard calculations.

All requests are signed with HMAC-SHA256 for integrity and authenticity.

Important Notes

Operational details that help you interpret your data correctly.

'Last Active' is based on session end time, not upload time. If you sync historical sessions (for example via Claude Desktop daemon), the date reflects when you actually used the tool.

API keys are permanent and do not expire unless you regenerate them.

Node.js 20+ is required.

Privacy mode is available if you want to hide your profile from the public leaderboard.
