Privacy Policy

What we collect, what we don't, and the third parties involved.

Effective: August 17, 2026 · Last updated: August 17, 2026

What we do not collect

The calculators run entirely in your browser. The dimensions, density, and prices you enter are used to compute your result on your device and arenot sent to us or stored on our servers. The optional browser-save and share-link behavior is explained below. We never ask for your address, and analytics events do not contain project specifics.

Analytics

No third-party analytics service is active as of the date above. The code is designed to record only broad interaction categories (for example, “result copied”) if analytics is enabled later, not the dimensions, price, area names, or other project values you enter. This section and the consent controls will be updated before activation.

Saved and shared calculator projects

The main calculator can save project inputs in your browser's local storage so they are available after a refresh. Those saved projects stay on your device unless you clear them. When you choose Share project, the measurements and calculation assumptions are encoded into the URL you copy; anyone who receives that link can read those project inputs. Do not put addresses, customer names, quote documents, or other sensitive information in area names.

Advertising (Google AdSense)

Google AdSense is not active as of the date above. If it is activated, Google and its advertising partners may use cookies, web beacons, IP addresses, and other identifiers to deliver, measure, personalize, and limit ads. Google's use of advertising cookies can allow Google and its partners to serve ads based on visits to this and other websites.

You can review or opt out of personalized advertising in Google Ads Settings. See How Google uses information from sites or apps that use its services and Google's list of certified third-party ad technology providers. When legally required for visitors in the EEA, United Kingdom, or Switzerland, a Google-certified consent management platform will be shown before personalized advertising is used.

Cookies

The current calculator uses browser local storage for saved projects; local storage is not an advertising cookie. If advertising or analytics is later enabled, first- or third-party cookies may also be used for preferences, security, measurement, frequency capping, and ad delivery. You can control cookies through your browser settings and, where available, the site's consent controls.

Data retention and your choices

We do not receive calculator projects saved only in your browser. You can remove those records by deleting saved projects in the calculator or clearing this site's browser storage. Shared project URLs remain wherever you or a recipient saved or posted them, so treat those links as readable project records and avoid including personal information.

Changes

We will update this page as our analytics and advertising setup changes. Material changes will be reflected here with a revised date.
