Last updated: 2026-04-06

Overview

CFCoach is a Chrome extension that helps Codeforces users with profile analysis, daily practice mixes, and contest generation.

Data We Process

The extension sends the following data to the CFCoach backend:

Codeforces handle(s) provided by the user.
Request parameters used to generate analysis, daily mixes, and contests.
Selected modes/tags for contest and practice generation.

The extension stores a handle locally in browser storage (chrome.storage.local) to improve UX.

Where Data Is Sent

Extension requests are sent to:

https://cpcoach.onrender.com

What We Do Not Collect in the Extension

The extension does not directly collect:

Passwords
Payment data
Personal documents

Backend Processing

Requests are processed by the CFCoach backend to return recommendations and generated results. Backend logs may include technical request metadata for reliability and debugging.

Data Sharing

We do not sell user data. Data is not shared with unrelated third parties for advertising.

Data Retention

Local extension storage can be cleared by the user via Chrome extension storage/site data controls.

Backend retention depends on server logging policy. If you want deletion requests supported, contact the maintainer.

Security

We use HTTPS endpoints for extension-to-backend communication.
