The messages that help most include:

Embedding and linking

The calculators are free to embed on your own site using the snippet on the homepage, and you're welcome to link to any page or print any chart for personal or office use. For anything beyond that, just ask.

What we can't help with

We build calculators — we can't give legal or payroll advice about your specific employment situation. For a wage dispute, start with your state's labor department or a local employment attorney; the disclaimer explains where our tools' job ends.
