Privacy
Privacy policy
Short version
We collect nothing about you. No signup, no email harvest, no cookies from us. The calculators run entirely inside your browser. Nothing you type into a calculator ever leaves your device.
What actually happens when you use the site
- You open a page. Your browser downloads the static HTML and JavaScript.
- You type dimensions and select a material. That input stays in the browser's memory. It is never sent to any server.
- You see a price range. It was calculated locally by JavaScript on your device.
- If you download or share the estimate as an image, that image is generated in your browser too. Nothing leaves your device unless you explicitly hit the Share button.
Third parties that may set cookies
- Google AdSense (if active on the page). Google's ad network uses cookies to personalize ads and measure performance. Their privacy policy: https://policies.google.com/privacy.
- Web hosting access logs. Our hosting provider records standard access logs (IP address, user agent, requested URL, timestamp) for security and abuse prevention. Logs are retained for 30 days maximum and are not correlated with any user identity.
We use no analytics that identify individuals. If we ever add analytics, it will be a privacy-first tool (Plausible, Umami or similar) that tracks aggregate traffic only, and this page will be updated before the change goes live.
Cookies you may see
If you have never interacted with AdSense on this site, no cookies from us or from Google should be set. If you have interacted with an ad, Google may set cookies according to their policy linked above. You can clear these at any time from your browser's settings, or install any tracker blocker of your choice — nothing on this site relies on those cookies to work.
Your data rights
Because we do not collect personal data, we have nothing about you to show, delete or export. If you are in the EU, UK or California and would like to confirm this in writing, contact us and we will reply.
Children
This site is not directed at children under 13 and does not knowingly collect information from anyone.
