Short because there is little to say
This is a set of static pages. There is no account to create, no form to submit and no script here that watches what you do.
Nothing that identifies you. There is no analytics package, no advertising tag, no social widget and no session cookie set by these pages. No profile is built, and there is nothing here to sell or share because nothing is gathered in the first place.
As with any website, the server that delivers these pages records ordinary technical request logs, which include an IP address, a timestamp and the file requested. They exist to keep the site running and to spot abuse, they are not linked to anything else, and they are not used to identify visitors.
The height calculator and the mount finder run entirely inside your browser. Your height, your screen weight and every other value you type stay on your own machine, are not transmitted anywhere and are not stored between visits. The figures they work from are embedded in the page itself, which is why they keep working with the network disconnected.
Following a buying link takes you to the retail partner, and from that point their privacy policy applies rather than this one. Their systems will recognise the referral, which is how the visit is attributed, and anything you enter at their checkout is held by them.
Fonts and images on this site are served from the same domain as the pages themselves. There is no external font service, no content network and no third-party request made while you read.
If you write to [email protected], the message is kept while the question is being answered and for a reasonable period afterwards in case of follow-up. It is not added to any list and no newsletter is sent from this site. Ask for it to be deleted and it will be.
