Privacy Policy

The calculators run entirely in your browser. Nothing you type into one is transmitted anywhere, including to us.

This page describes what GreenhouseSetup.com collects and what happens to it. It is written to be read rather than to be exhaustive at your expense.

The calculators do not send anything

Worth saying first. Every calculator here runs in your browser as JavaScript. Greenhouse dimensions, target temperatures, zone, crop choices, water and soil figures: all computed locally, none transmitted. There is no server-side calculation on this site and no record of what you entered.

Analytics

Google Analytics 4 records aggregate usage: which pages are visited, approximate location at city level, device type and where visitors arrived from. It is used to see which pages and calculators are actually useful, and it is not tied to an identity. Google's own handling is described in its privacy policy, and you can opt out of Analytics entirely with the official browser add-on.

Forms and email

If you submit the contact form or ask for a greenhouse build list, the email address and message you enter are stored in a Google Forms spreadsheet and reach [email protected]. That address is used to reply and, if you asked for it, to send the build list. It is never sold, rented or shared with third parties. Ask through the contact page and it will be deleted.

Affiliate links and cookies

Some outbound links are affiliate links, and following one may set a cookie at the retailer so a resulting purchase is attributed here. That is how the site earns, and it is described on the affiliate disclosure page. This site runs no ad network and sets no advertising cookies of its own. Block cookies if you prefer and every calculator and chart here still works normally.

Children

This site is not directed at children under 13 and does not knowingly collect their information. Growing plants is a good thing for children to do, but the purchasing and structural content here assumes an adult reader.

Changes and contact

If this policy changes, the current version always lives at this URL. Questions go to the contact page. See also the affiliate disclosure and the disclaimer, which covers the limits of the growing, structural and electrical guidance.
