What we collect

Calculator inputs. The figures you enter into our calculators are processed in your browser. They are not sent to our servers or stored.

Basic technical data. Our hosting provider, Cloudflare, processes standard request data (such as IP address, browser type and the pages requested) to deliver and secure the site.

Messages. If you email us, we receive your email address and message and use them only to reply.

Cookies and advertising

Third parties

Links to other sites, including affiliate partners, are governed by those sites’ own privacy policies.

Under UK data protection law you can ask what personal data we hold about you, and ask us to correct or delete it. Email hello@cashmaths.com. You can also complain to the Information Commissioner’s Office at ico.org.uk.
