Privacy

The calculators run entirely in your browser. The numbers you enter are saved only in your own browser (local storage) so they're still there next time, and we don't receive them.

We may use privacy-friendly product analytics (PostHog) to see which tools get used and which pages people leave, so we can improve them. This records page views and clicks, not your name or contact details.

When you click a retailer link, that retailer's own privacy policy applies.
