Personally identifiable information
We process account-level profile data associated with your CPTracker account, such as user ID and username/email when available, only to identify your account and sync your problem tracking data.
CPTracker Extension Privacy Policy
This page explains what data categories are handled by the CPTracker browser extension and why each category is needed to provide the extension single purpose: tracking LeetCode solving sessions for your CPTracker account.
Last updated: March 9, 2026
Authentication information
We use your existing cptracker.org authenticated session state to authorize extension requests. We do not collect passwords or PINs in the extension popup.
Web history
When you open the extension popup, we read the active tab URL only to confirm it is a LeetCode problem page and connect that problem to your CPTracker account.
Website content
We process the LeetCode problem link (URL/hyperlink) as website resource content so your timer, notes, and status updates are saved for the correct problem.
How data is used?
We do not sell user data. We do not use user data for advertising. We only use these data categories to power extension features such as problem linking, timer actions, notes updates, and analytics sync with cptracker.org.
