A dot marks a day the store showed a different number. Between them the line carries the last one forward: we read every listing up to 2 times 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.
