N·Q·M

Privacy Policy

Last updated: 11 June 2026

Network Quality Monitor (NQM) is designed to be completely private. Its single purpose is to measure your internet connection's quality, locally, for you.

What we collect

Nothing. NQM does not collect, store, transmit, sell or share any personal information or usage data. There are no accounts, no analytics, no advertising, no third-party trackers and no servers of ours.

Network requests it makes (and why)

Measuring a connection requires using it. NQM periodically sends small, empty HTTPS GET requests and times the round trip. They go to standard public connectivity-check endpoints:

www.gstatic.com/generate_204 and www.google.com/generate_204 (Google)
cp.cloudflare.com/generate_204 (Cloudflare)
8.8.8.8/resolve / dns.google/resolve — a DNS-over-HTTPS lookup of g.co (Google Public DNS)

These requests carry no personal data and no cookies (credentials are explicitly omitted) — just a cache-busting number. Responses are discarded; only the elapsed time is used. As with loading any web page, the operators (Google, Cloudflare) observe an ordinary anonymous HTTPS request from your IP address, governed by their own privacy policies. You can choose the probe target in settings.

What's stored on your device

Your settings (check interval, probe target, alert toggles).
About 24 hours of measurement history (timestamps, latency, jitter, loss, score).

Both live in chrome.storage.local in your browser, never leave your device, and are deleted when you remove the extension.

Permissions explained

alarms — schedule the periodic background checks.
storage — keep settings and local history.
notifications — alert you when call quality degrades or recovers (can be switched off).
No site access. The timing probes are sent as no-cors requests, so NQM needs no host permissions at all — it cannot read your browsing, tabs, or any page content. The only permission you're asked to grant at install is "Display notifications".

Data sharing

Because no data is collected, no data is ever shared with anyone.

Children's privacy

NQM collects no data from anyone, including children.
