weareleaking scans localStorage and sessionStorage on every website you visit and shows you what's being stored without your knowledge. It detects cross-site trackers, advertising networks, fingerprinting IDs, and exposed personal data using pattern matching against known tracking systems like Google Analytics, Facebook Pixel, Segment, HotJar, and more. Open the popup for a quick per-site verdict — how many items are flagged, what categories they fall into, and how much data the site is keeping locally. Everything runs in your browser. No data is collected, transmitted, or shared.
