Our own code

The tools and page layouts are written for this site. The pages make no requests to other servers; links and numbers you enter are processed in your browser and never uploaded.

Third-party material

No third-party code, fonts or data sets are used. The rules we follow (Google Analytics campaign parameters and default channel groups, Google Ads ValueTrack parameters, Meta URL parameters, standard statistics formulas) are named on each tool page.
