Calculator inputs
The calculators run entirely in your web browser. The measurements and prices you type are not sent to us or stored on our servers.
Google Analytics
We use Google Analytics to understand how visitors use the site, such as which pages are viewed, roughly where visitors are in the world, what device and browser they use, and how they arrived. Google Analytics uses cookies and similar technologies to collect this information, and Google processes it under its own privacy policy. We use the reports to improve the site, not to identify individual visitors.
You can block analytics cookies in your browser settings, or use Google’s opt-out browser add-on.
Fonts
Pages load fonts from Google Fonts. When your browser requests a font, Google receives your IP address, as with any web request.
Advertising
The site does not currently show ads. If that changes, this policy will be updated to describe the advertising partners and the cookies they use.
If you email us, we receive your email address and whatever you write, and use them only to reply. We don’t add you to a mailing list.
Children
The site is a general-audience gardening resource and is not directed at children under 13. We don’t knowingly collect their personal information.
Your choices and rights
Depending on where you live, you may have rights to access or delete personal information about you. Because we hold very little, the main thing we may have is an email you sent us. Contact hello@topsoilcalculators.net and we’ll help.
Changes
If this policy changes, the date at the top of the page will change too.
