Privacy & cookies
The short version: everything you type into our calculators stays in your browser. The maths runs on your device, and your salary, savings and family details are never sent to us or anyone else.
Analytics
We use Google Analytics 4 to understand which calculators and guides people find useful — page views, approximate location (country/region), device type and how visitors move around the site. We use this to decide what to build and fix. We do not run advertising, and we do not sell or share data for marketing.
Analytics cookies are only set if you choose Accept analytics on the cookie banner. If you decline, Google Analytics runs without cookies and without persistent identifiers. You can change your mind at any time via the Cookie choices link in the footer of every page, which shows the banner again.
What we store on your device
One small item of local storage (tmc_consent) remembers your cookie choice. If you accept analytics, Google sets its standard _ga cookies to distinguish visitors. Nothing else is stored.
Hosting
The site is served by Cloudflare, which processes visitor IP addresses transiently to deliver pages and protect against abuse, as any web host does. We do not receive server logs identifying you.
