Is Carbonalyser safe?
Carbonalyser records per-site response byte totals locally while its user-started traffic analysis is running.
When you start Carbonalyser's analysis, it observes responses for all requested URLs and keeps a running byte total by site. The extension stores those totals in local browser storage and uses them in the popup to estimate bandwidth use and carbon impact.
