The numbers you enter
All calculations on AdCalc run in your browser. The values you type into a calculator are not sent to us or to any third party, and we do not store them.
Hosting and server logs
The site is a static website served by our hosting provider. Like any web host, the provider may process standard technical data when you load a page, such as your IP address, browser type and the pages requested, to deliver the site and keep it secure.
Cookies, analytics and advertising
At the time of writing the site does not set advertising or tracking cookies and does not run analytics. If we add analytics, advertising or email sign-up in future, we will update this page first and ask for consent where the law requires it.
Sponsored and external links
Some pages may link to other websites, including sponsored (affiliate) links, which are labelled as such. Those sites have their own privacy practices, which we do not control.
Changes to this policy
If this policy changes, the date at the top of this page will change with it.
