The calculators on this site run entirely in your browser. The numbers you type are not sent to us or stored by us.

We do not use accounts, forms or cookies of our own. The hosting provider may keep standard server logs (such as IP address and pages requested) for security and reliability.

If we add advertising later (for example Google AdSense), third-party vendors including Google may use cookies to serve ads based on prior visits to this and other sites. You can opt out of personalized advertising at Google Ads Settings or aboutads.info. This page will be updated before any ads go live.

Links to template stores (Payhip) and official government sites are governed by those sites' own policies.
