Overview

GradeIQ is a Chrome extension that displays graded card population data and average sale prices on eBay listings. This policy explains what information we collect, how we use it, and your rights regarding your data.

Analytics

We use PostHog to collect anonymous usage analytics. Events include actions like opening the extension, viewing tabs, clicking cards, and signing in. No personally identifiable information — such as your name, email, or browsing history outside of eBay graded card listings — is included in these events.

Analytics events are associated with a randomly generated anonymous ID stored locally on your device. If you create an account, events are linked to your account's internal UUID — never your email address.
