Terms of Use

Last updated September 2026

These terms cover rogerbisschoff.com, its nine linked diagnostic tools, and the commercial Insights published here, all operated by Roger Bisschoff.

The tools are free and for informational use

Every diagnostic tool linked from this site is free to use, with no account or login required. Each tool's output is a general commercial estimate based on the figures you enter — it is informational, not a guarantee of any specific commercial outcome, and does not constitute financial, legal, or tax advice.

Accuracy

Reasonable care goes into each tool's methodology and into the commercial observations published as Insights, but neither is warranted to be complete, current, or error-free. You remain responsible for your own commercial decisions.

Attribution

The diagnostic tools' frameworks and Insights are free to cite; the underlying frameworks themselves remain Roger Bisschoff's own work. Vendors or platforms wishing to integrate them into a product should get in touch first — see the Contact link on the homepage.

Changes

These terms may be updated from time to time as this site grows; the "last updated" date above reflects the current version.
