The calculators run in your browser. Your numbers are not sent anywhere.
Every calculation on this site runs in your browser using JavaScript. The amounts, rates and terms you type are not transmitted to us, not stored on a server, and not associated with you. Reloading the page discards them. If you press “Copy link to this calculation”, the figures you entered are written into the copied link (the part after the # in the address) so that whoever opens it sees the same calculation. That text lives in the link itself, is not sent to us when you calculate, and contains your figures only because you chose to copy and share it.
We use analytics to understand which pages are used and how they are found. Analytics may record the page you visited, the referring source, approximate location derived from IP address, browser and device type, and interactions such as which inputs were changed. It does not record the values you entered into a field.
Analytics and advertising cookies are set only after consent is given. Until you make a choice, every non-essential storage signal is set to denied by default and no analytics cookie is written to your device, so an un-consented visit is not tracked with cookies. You can change or withdraw your choice at any time using the Cookie settings link in the site footer. Where consent is refused, the non-essential scripts are not loaded.
There is currently no advertising on this site and no advertising script is loaded. If advertising is introduced, it may be served by third-party networks, which may use cookies or similar technologies to measure and target advertising. Where required, those would be subject to the consent choice above, and this section would be updated at that point rather than left to describe something that is not yet true.
You can withdraw consent, block cookies in your browser, or use the contact address to ask what is held about you. Because the calculators do not transmit your inputs, there is normally nothing to retrieve beyond analytics data.
Material changes to this policy will be dated here rather than applied silently.
