CabinGrade (called SeatSpec until November 2026) is a browser extension that adds seat information to Google Flights results. The short version: it does not collect anything about you.
On Google Flights pages (google.com/travel) CabinGrade reads the flight results Google has already sent to your browser: airline, aircraft, seat type, legroom and amenities. It uses them to draw one line under each result. This happens inside your browser. None of it is sent to us or to anyone else.
Nothing about you or your searches. Once a day the extension downloads the current list of airline seat layouts from this site. It is one static file, the same for everyone. The request carries no cookies, no account, no identifier and nothing about what you searched. Like any web request it reaches our hosting provider, Cloudflare, from your IP address. We do not log or analyse those requests.
Only that list of seat layouts, kept in the extension's own storage in your browser. No search history, no flights, no personal data.
No analytics. No ads. No affiliate links. No tracking. No accounts. No selling or sharing of data, because there is none to sell or share.
If this ever changes, this page will say so before the extension does it.
Questions go to the support email on the CabinGrade page in the Chrome Web Store.
