Your water test stays in your browser

The treatment planner runs entirely on the device. Test values are never transmitted to a server, because there is no server to transmit them to: the site is a set of static files and the calculation is JavaScript running locally.

Sharing a result puts the values in the page address so the link reproduces the same plan. Anyone holding that link can read those numbers, so treat a shared planner link as you would the report itself. Analytics strips the address of its query string and fragment before recording a visit, so shared values do not reach the analytics provider either.

Analytics

WellWise Labs uses Vercel Web Analytics and Speed Insights, which count page views and measure loading performance without cookies and without building a profile of individual visitors. There is no advertising network on this site, no retargeting pixel and no cross-site tracking.

Outbound links to retailers and manufacturers may carry a tracking parameter identifying this site as the referrer. The destination's own privacy policy governs what happens after the click.
