Last updated 10 October 2026
ShelfScout analyses Amazon search and product pages in your browser and checks phrases for trademarks.
Stays in your browser
Rankings, prices and estimates are read and calculated from the Amazon pages you open. Tracked titles, BSR history and keyword lists stay in your browser.
Sent to our server
Trademark checks: the phrases to check (for example from a title you are writing). Results are cached for 7 days and shared across users without recording who asked.
A daily count of free checks.
Like every extension we make: your install id, your licence if you have one, usage counts for plan limits, and optional “Help improve” data if you turn it on. See the main privacy policy.
Other services
Marker API: USPTO trademark search (phrases only).
