This extension processes and stores problem metadata selected by the user (problem title, URL, tags, status and timestamps). When GitHub sync is enabled, this metadata is transmitted directly to a GitHub repository to store the user’s data. No personal identifiers, browsing history, or analytics are collected. No data is transmitted to any server other than GitHub. The extension does not track user activity outside supported Codeforces pages. The GitHub token used is limited to repository access and is not used for any other purpose..
