Affiliate disclosure

Last updated: 21 July 2026

FitTools may include affiliate links — links to products or services where we earn a commission if you make a purchase, at no extra cost to you. At the time of writing, no affiliate offers are live on the site; this disclosure exists so the rules are public before any appear.

Our commitments

• Every affiliate placement is accompanied by a visible disclosure line, and affiliate links are marked with rel="sponsored" so search engines see them for what they are.
• Affiliate relationships never influence calculator formulas, results, editorial conclusions or which tools we build. Formulas are locked to their published sources and tested against them.
• We only consider recommending products of the kind we would use ourselves, and clearly separate recommendations from calculator output.

Questions about a specific placement are welcome via the site’s contact details.
