Privacy notice

What this version does

The public pages provide editorial information and an in-browser calculator. Calculator values remain in your browser and are not submitted to us. We do not currently offer accounts, comments or an email signup form.

External links

Clicking an external website sends you to that provider, whose own privacy and cookie policies apply. Future affiliate links may include a tracking identifier so the provider can attribute a qualifying sale.

Click measurement

Outbound recommendation buttons emit a descriptive browser-side event. No third-party analytics provider currently receives those events. Affiliate merchants may measure visits and sales after you leave this site under their own policies.

Future analytics or email tools

This notice will be updated with the provider, purpose, legal basis, retention, transfers and consent mechanism before any non-essential analytics or email-list tool is activated.
