Privacy Policy
Last updated: December 27, 2024
This privacy policy describes how the CF-Tool Login Helper Chrome extension handles your data.
TL;DR: This extension only communicates with your local machine. No data is ever sent to external servers.
What Data We Collect
The extension accesses the following data only when you initiate a login through cf-tool CLI:
- Session Cookies: Codeforces session cookies (required to authenticate cf-tool)
- Username: Your Codeforces handle (displayed on the page)
How We Use Your Data
The collected data is used exclusively to:
- Transfer your authenticated Codeforces session to the cf-tool CLI running on your local machine
Where Your Data Goes
Your data is sent only to localhost (your own computer):
- The extension sends cookies to
http://localhost:{port}/callback
- The {port} is dynamically assigned by cf-tool on your machine
- No data is ever sent to external servers
- No data is stored by the extension
Permissions Explained
- codeforces.com access: To read your login status and cookies
- localhost access: To send cookies to cf-tool running on your machine
- cookies permission: To read authentication cookies from Codeforces
Third-Party Services
