Is having Quantum Metric on my site illegal?

No. The complaints do not claim the script is illegal; they claim it recorded a visitor before the visitor consented, or kept recording after the visitor declined. Loading Quantum Metric only after consent, or removing it when it is not used, is what removes the pattern the complaints describe.

How do I know if Quantum Metric fires before consent on my site?

Run the free scan. It loads your pages without clicking anything and checks every request that leaves the browser against its tracker catalog, recording the millisecond each match fired. If Quantum Metric appears, it fired before consent. When your banner has a reject button, the scan clicks it and reports whether the script kept firing.

Where do the case counts on this page come from?

From the complaint text of verified California Invasion of Privacy Act filings. When a complaint names this script, the case is linked to it. Complaints that are not yet available in the public record are not counted, so the number is a floor.

The short answer

Quantum Metric is a session replay tool from Quantum Metric. Suitcast rates its risk under the California Invasion of Privacy Act, CIPA, as critical, because complaints describe scripts like it recording visitors before they consent. The fix is to load it only after a visitor accepts, or to remove it when it is not used.

Why complaints name it

It is named in several California privacy complaints for capturing visitors' clicks and typing without permission.

The act allows $5,000 per violation, which is why firms look for scripts that run the moment a page opens.

The fix

How to stop Quantum Metric firing before consent

Written for the person who runs the site, with the setting to change.

Ask your developer to start the recording script only after the visitor accepts your cookie banner and to mask every form field.
Remove it if no one reviews the replays.

How the scan checks this

Loads your pages like a first visit. A real browser, nothing clicked, nothing accepted.
Checks every request before the banner is answered. A request to cdn.quantummetric.com is matched to Quantum Metric and recorded with the millisecond it fired.
Clicks reject and watches again. When the banner has a reject button, the scan presses it; if Quantum Metric keeps firing, the report says so.
