Is MetricMaster safe?

Medium risk

MetricMaster sends searches typed on its new tab page to meter.metermaster-ext.com with a fixed tracking ID.

MetricMaster replaces Chrome's new tab page with its own unit-conversion and search page. When you submit a search from that page, it redirects the browser to meter.metermaster-ext.com with your query in the q parameter and tid=990304.

info

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data

Destinations our analysis observed MetricMaster contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • meter.metermaster-ext.com

    MetricMaster sends data to meter.metermaster-ext.com. No other extension we have analysed sends data here.
