Privacy policy
This site is designed to collect as little about you as possible.
What the tools do with your inputs
The sizer and calculators run in your browser. The room size, options and other values you enter are not sent to us or stored on our servers.
What we store on your device
If you switch on the high-contrast option, we save that choice in your browser's local storage so it remembers next time. It isn't sent anywhere and you can clear it in your browser settings.
Analytics and cookies
At the time of writing we don't use visitor analytics or advertising cookies on this site. If that changes, we'll update this page and add a cookie notice where one is needed.
Google Search Console
We use Google Search Console to see how this site appears in Google Search, such as which searches lead to our pages. It reports data from Google's search results. It doesn't add tracking to this site or set cookies on your device.
Server logs
The site is hosted by Cloudflare. Like most web hosts, Cloudflare processes technical data such as your IP address and browser details to deliver pages and protect against abuse. See Cloudflare's privacy policy.
Affiliate links
When you click an affiliate link, you leave this site. The affiliate network and the seller may set cookies and collect data under their own policies, so we encourage you to read theirs. We receive reports of sales, not your personal details.
If you email info@airsum.co.uk, we use your address and message only to reply, and we delete it when it's no longer needed.
Your rights
Under UK data protection law you can ask what personal data we hold about you, and ask us to correct or delete it. Email us to do so. You can also complain to the Information Commissioner's Office.
