Cookie Policy
This site uses analytics cookies and nothing else, and they are never used to identify you. In the European Economic Area, the United Kingdom and Switzerland they stay switched off until you accept. Anywhere, you can switch them off from the footer of any page.

What cookies are
Cookies are small text files a website asks your browser to keep. They are sent back to the site on every subsequent request, which is what lets a site recognize a returning visitor. Session cookies disappear when you close the browser; persistent cookies stay until they expire or you delete them.
Local storage is a related but separate technology. It also keeps small pieces of data on your device, but unlike a cookie it is never sent to a server. It is read only by JavaScript running on the page you are already looking at.
What this site uses
A local storage entry that remembers your choice, a session entry that remembers which country your visit comes from, plus Google Analytics cookies. Where you are decides when those cookies may be set, as the next section explains.
| Name | Type | Purpose | Set when |
|---|---|---|---|
cookie_consent | Local storage | Remembers whether you accepted or declined, so the banner stops asking | You press Accept or Decline |
geo_cc | Session storage | The two-letter country code of your visit, so the site knows whether to ask before setting cookies | Your first page; gone when you close the tab |
_ga | Cookie | Google Analytics, distinguishes one visitor from another | In the EEA, UK and Switzerland, only after you accept. Elsewhere, on your first visit unless you opt out |
_ga_* | Cookie | Google Analytics, keeps session state | In the EEA, UK and Switzerland, only after you accept. Elsewhere, on your first visit unless you opt out |
There is no advertising on this site, so no advertising network is setting anything here. If that changes, this page will be updated before the ads appear rather than after.
Who is asked first
Everything here runs under Google Consent Mode, and every consent signal starts at denied before any third-party tag runs. On the first page of a visit, the site then asks Cloudflare, which serves it, which country the visit comes from. Cloudflare works that out from your IP address. The site keeps only the two-letter country code, for as long as the tab stays open.
In the European Economic Area, the United Kingdom and Switzerland, every signal stays denied and the banner asks you. No cookie is written and nothing is recorded until you press Accept. If your country cannot be worked out, you are asked too.
Everywhere else, there is no banner. Analytics cookies are switched on from your first page, and you can switch them off at any time with Cookie Preferences at the bottom of every page.
Pressing Accept switches four signals to granted: analytics storage, ad storage, ad user data and ad personalisation. Only the first is actually used today, because there is no advertising here, but all four are named so the picture is complete.
Pressing Decline sets all four to denied. The banner disappears, your choice is remembered, and no analytics cookie is written from then on. Every calculator on the site works identically either way. Declining costs you nothing.
What the analytics data shows us
Aggregate numbers: which calculators get used, roughly where visitors are in the world, which pages people land on, and whether something is broken on a particular browser. It is how we decide which calculator to build next.
It does not include anything you type. The dimensions, prices and lawn sizes you enter are worked out in your browser and never transmitted, with or without consent. That is a property of how the calculators are built rather than a promise about configuration.
Changing your mind
Click Cookie Preferences at the bottom of any page, wherever you are. That clears your stored choice, sets every consent signal back to denied and reloads the page with the banner showing, so you can accept or decline. Outside the European Economic Area, the United Kingdom and Switzerland, this is how you opt out.
You can also clear cookies through your browser settings, use Google’s Analytics opt-out browser add-on for a blanket opt-out across all sites, or block cookies for this domain entirely. Nothing here breaks if you do.
Changes to this policy
If what the site stores ever changes, this page is updated first and the date at the top changes with it. We would rather tell you plainly than quietly alter what happens on your device.
