Optional visitor analytics
If you choose “Accept analytics,” we load Google Analytics to measure page visits, device and browser information, approximate location and interactions such as guide downloads and clicks on Amazon links. Google Analytics uses cookies to distinguish visits. This helps us understand which guides and tools are useful.
Google Analytics does not load until you accept. We disable advertising personalization and Google signals in our site tag, remove query strings from the page address and referring address we configure, and do not ask for your name or email. Google may process analytics data on servers outside your country. Learn more about how Google uses information from sites that use its services.
Your cookie choice
We remember your accept or decline choice in this browser for up to 180 days. Analytics cookies are configured to expire after 180 days and may refresh when you return. Use “Cookie preferences” in the footer at any time to change your choice. Declining stops future analytics collection and clears this site's Google Analytics cookies; it does not erase data already received by Google. Clearing browser storage removes your saved choice.
Our lawn calculators work in your browser. We do not send the lawn dimensions or watering measurements you enter to our server.
Hosting and security
Cloudflare delivers this website over HTTPS and may process technical request information, including IP addresses, to serve pages, operate its network and protect the site. This delivery and security processing is separate from optional Google Analytics. See Cloudflare's privacy policy.
Amazon links
Amazon links contain our Associates tracking ID. If you follow a link, Amazon handles your visit and any purchase under its own privacy notice. Declining analytics on this site does not change an Amazon affiliate link or your preferences on Amazon. We do not receive your Amazon payment details. Read our affiliate disclosure.
