Privacy policy
Effective 26 October 2026. This policy explains what data ExteriorMath (https://exteriormath.com) collects, why, and the choices you have.
Who we are
ExteriorMath is owned and operated by Sawera Nadeem. You can reach us at exteriormath@gmail.com.
Calculator inputs stay in your browser
The calculators run in your web browser. The measurements you enter are processed on your device and are not sent to or stored on our server. When you use Share link, your inputs are written into the page address (URL) only, so anyone you send the link to can see them.
If you tick items on a materials list, the ticks are saved in your own browser (local storage) so they are still there when you come back. They never leave your device, and clearing your browser data removes them.
Server logs
Our website is hosted by Hostinger. Like most hosts, Hostinger keeps server logs for security and reliability. These logs record your IP address, browser type, the pages requested and the time of each request.

We use Google Analytics 4 to understand how visitors use the site, for example which pages are visited and how people arrive. Google Analytics measures visits using cookies or similar technologies. You can read how Google uses information from sites that use its services, and you can opt out with the Google Analytics opt-out browser add-on.
