Privacy Policy

Calculator Data

All calculations are performed entirely in your browser. Your deck dimensions, material choices, and cost inputs are never sent to our servers or any third party. When you use the Save feature, inputs are stored in your browser's localStorage — a client-side storage mechanism that keeps data on your device only. We cannot access, read, or recover your saved data.

Contact Form

If you use our contact form, your name, email address, and message are sent via EmailJS to our email inbox. We use this information solely to respond to your enquiry. We do not add you to mailing lists or share your contact details with third parties.

Analytics

We use Google Analytics 4 to understand how visitors use the site — which pages are viewed, how long visits last, and general geographic information. This helps us improve the calculator and content. Analytics tracking respects your consent preferences and is only active if you accept analytics cookies via the consent banner.

Advertising

We display advertisements via Google AdSense to support this free service. Google may use cookies to serve ads based on your prior visits to this or other websites, subject to your consent preferences. You can manage your ad personalisation settings through the consent banner or Google's Ad Settings page.

Cookies

We use essential cookies for site functionality and optional cookies for analytics and advertising. You can manage your cookie preferences at any time using the "Manage Privacy" link in the site footer. The calculator itself does not use cookies — it uses localStorage, which is not sent with HTTP requests.

Your Rights

You can clear all saved calculator data by clearing your browser's localStorage. You can opt out of analytics and advertising cookies via the consent manager. For any privacy-related questions, contact us at our contact page.
