Calculator inputs
The budget calculator runs in your browser. The calculation runs locally in your browser; our page code does not transmit the numbers to our servers, create an account, or store them in a database. The calculator does not intentionally save inputs between page visits.
Cookies and analytics
Our website code does not intentionally set analytics or advertising cookies, and we do not embed advertising, tracking pixels or third-party analytics scripts. Cloudflare may apply necessary security measures and process technical information when requests reach its network. If we introduce analytics, ads or embedded media, we will update this notice and implement any legally required consent controls before doing so.
