Permission Trail

When people talk about “website storage,” most think only of cookies — but that’s just the tip of the iceberg. Modern sites hide data in local storage, IndexedDB, cache layers, and even background scripts you never see. Most tools only show cookies, and existing privacy extensions don’t give you a real dashboard to actually see what’s happening behind the scenes. I built Permission Trail because people deserve transparency. We’re surrounded by silent scripts and quiet trackers that leave long-term footprints on our devices, yet no one shows you the full picture. Permission Trail finally does — clearly, visually, and privately — so you can understand what websites leave behind and take control before it builds up into something you never even realised was there. Here’s exactly what Permission Trail tracks: 1) Cookies — small trackers sites use to identify you, remember sessions, or follow you across the web. 2) LocalStorage — persistent data stored by sites that isn’t cleared automatically, often used to track users even after logouts. 3) IndexedDB — a powerful browser database many websites use to store large or hidden data, often without your awareness. 4) Cache Storage — files saved behind the scenes that can reveal usage patterns or keep trackers alive even after clearing cookies. 5) Service Workers — background scripts that run even when you’re not on the site, capable of syncing, tracking, or re-caching data. 6) Form Data — autofill-related information or saved form entries that can linger longer than you expect. If a site plants something on your device, you’ll see it — instantly, visually, and in plain English. No guessing, no digging through dev tools, no blind trust. Just the truth.
