A dot marks a day the store showed a different number. Between them the line carries the last one forward: we read every listing more than once a day and record a point only when something moves. History beyond ninety days is in the app.

What it can reach

No site access is declared in the manifest, so it cannot read the pages you open on its own.

  • See the address and title of every tab you have open tabs
  • Run its own code on the pages it can access scripting
  • Store data in your browser storage
