Plans saved on your device
Saving a plan uses this browser’s local storage. It stores bed shapes, measurements, relative positions, selected catalog products and planning preferences. It does not create an account or synchronize your devices. Clearing site storage removes the saved plan.
Shared links include the plan in the part of the URL after the # symbol. Anyone with the link can read those measurements. Downloaded files contain the same plan fields. Private soil quotes and water-pressure readings are excluded from saved and shared plans. Private quote fields are also hidden when printing.
Site measurement
We use Plausible and Google Analytics to understand which pages and tools are useful. Measurement includes page visits and actions such as using a tool or following a product link.
Tool events use fixed action categories. They do not include calculator inputs, water pressure, private quotes, uploaded plans or contact messages.
Google Analytics is configured with analytics and advertising storage denied. This still allows measurement requests. Google receives connection information, such as your IP address and browser details. We send Google the page address without its query string, fragment or referring address.
Plausible provides aggregate reports about page visits, referring pages, time spent and scrolling. We send it the page address without its query string or fragment. Its service also receives your referring address, IP address and browser details.
If you are in the EU, the EEA or the UK
We rely on legitimate interests to run aggregate, cookieless measurement of which pages and tools are useful. Because analytics and advertising storage are denied by default, we do not ask for consent to set tracking cookies, and none are set.
Our measurement and hosting providers sit outside the EEA. Google LLC (Google Analytics), Amazon (product photographs and product links) and our own Plausible instance receive connection information, including your IP address, when a page or an image loads. Standard contractual clauses cover the transfers our providers operate under.
You can ask what we hold about you, ask for it to be deleted, or object to this measurement. We hold no account, no mailing list and no identifier for you, so the practical answer is usually that there is nothing to return. Use the contact page and we will answer.
If a display advertising network is added to this site later, it will bring its own vendors and its own consent request, and this page will say so before that happens.
The other companies involved
Cloudflare routes and protects the domain. Plausible Analytics, our own instance, measures page visits. Google Analytics measures page visits and tool use in the denied-storage state described above. Amazon serves product photographs at page load and receives the request when one is displayed. Amazon also records the referral when you follow one of our product links, which is how the site is funded. The affiliate disclosure sets that out in full.
Following any product or source link opens a site with its own privacy practices. No purchase is processed here and no payment detail ever reaches this site.
Product images and retailer links
Product photos may load directly from Amazon, which receives the network information needed to serve the image, including your IP address. Opening a retailer link takes you to a separate website with its own privacy practices.
