Privacy Policy
Last updated: September 22, 2026
What this site collects
The calculators on Siding Calculator run entirely in your browser. Measurements, prices, and other values you enter into a calculator are not sent to our servers — they may be saved to your browser's local storage so your progress is preserved if you return to the same calculator, but that data never leaves your device and is never visible to us.
Contact form and email
If you email us directly (for example, via the contact page), we receive whatever information you choose to include in that message, such as your email address and message content. We use this only to respond to your inquiry.
Analytics
This site uses Google Analytics (GA4) to understand how visitors use the site — for example, which calculators are used most and how people navigate between pages. Google Analytics collects information such as pages visited, approximate location (derived from IP address), device and browser type, and time spent on a page. We do not use Google Analytics for ad personalization or combine it with other data that identifies you individually. You can opt out using the Google Analytics Opt-out Browser Add-on or by blocking analytics cookies in your browser settings. Visitors in the EU are shown a consent banner and Google Analytics only loads after that consent is given.
Advertising
This site does not currently run any advertising. Its layout reserves space for ads that are not active until an advertising provider is configured; if that changes, this section will name the provider (e.g., Google AdSense), describe any cookies used for ad personalization, and link to an opt-out where available.
Cookies and local storage
This site may use browser local storage to remember calculator inputs between visits on the same device. Google Analytics sets cookies to distinguish visitors and sessions — see the Analytics section above for details and how to opt out. If an advertising provider is added in the future, this policy will be updated to disclose any cookies it sets.
Third-party links
This site may link to third-party resources, including manufacturer websites and, in the future, affiliate or lead-generation partners (see our Affiliate Disclosure). We are not responsible for the privacy practices of external sites.
Children's privacy
This site is not directed at children under 13 and does not knowingly collect information from them.
Changes to this policy
We may update this policy as the site's features change. Updates will be posted on this page.
