Is having Mouseflow 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 Mouseflow only after consent, or removing it when it is not used, is what removes the pattern the complaints describe.

How do I know if Mouseflow 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 Mouseflow 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

Mouseflow is a session replay tool from Mouseflow. 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

Session recording of this kind is what most California privacy complaints describe as recording a visitor without consent.

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 Mouseflow firing before consent

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

Mouseflow has a setting to require opt-in before recording; turn it on and connect it to your cookie banner or Google Tag Manager consent mode.
Remove the script if you are not using the recordings.

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.mouseflow.com is matched to Mouseflow and recorded with the millisecond it fired.
Clicks reject and watches again. When the banner has a reject button, the scan presses it; if Mouseflow keeps firing, the report says so.

Scanner rules and limits are on the methodology page.
