Privacy Policy
Last updated: 2026 · Owner-configurable document — the site owner is responsible for keeping it accurate.
Calculator data never leaves your browser
Everything you enter into a calculator — dimensions, depths, areas, prices — exists only in your browser tab. It is not transmitted to any server, not stored by us, and not readable by us. We provide no accounts, so there is no profile to attach data to. We do not persist calculator inputs to browser storage either; reload the page and your numbers are gone.
Analytics (optional, and only with your consent)
If the site has Google Analytics 4 enabled, we ask before it loads. You can "Allow analytics" or "Decline" — declining (or ignoring the banner) means no analytics cookies are set and no analytics data is collected from you.
You do not enter any project data into the banner question: analytics events only contain the name of the calculator you opened and simple facts like "results copied". We do not transmit your dimensions, quantities or prices to Google Analytics. Google may still process standard identifiers, IP addresses (truncated) and general browsing information — read Google's Privacy Policy for exactly what Google collects. Another honest note: consent rules differ by jurisdiction (for example, the EU's ePrivacy rules and Google's certified consent-management requirements for certain regions). This banner is a good-faith preference control; if you operate in a region with stricter consent law, additional measures may be required.
What is stored in your browser
- One local preference entry (
ypq.consent.v1): records your analytics choice locally. Not a tracking cookie — it stays in your browser's local storage and is only read back by this site. - No project measurements — we deliberately never persist your inputs.
- Google Analytics may set its own cookies or similar identifiers on our pages only when analytics is enabled AND you consented.
Advertising (future)
Display advertising may come later once the site qualifies with an ad network such as Google AdSense. Right now there is no ad code on the site. If advertising is introduced, this policy will be updated to name the provider, describe cookies and consent requirements then in effect, and separate ad consent from analytics consent. You will see the change reflected in this page before any ad script loads.
Server logs & hosting
Like every website, our static hosting provider records standard request logs (IP, timestamps, URLs, user agents) which we don't use for profiling. The pages themselves are cached globally by the CDN; because we use no cookies for core functionality, you can calculate anonymously and unaffected by choosing "Decline".
Links to other sites
Outbound links (for example to Google's policies) are external websites that this policy does not cover. Check their own privacy pages.
Your choices
To change your analytics preference, open the site fresh in a private window, and you'll be asked again; browser extensions and per-site settings also work. To request anything else, use the contact page.
