Cookie policy

This page is not finished It still needs the trader's legal name and a geographic business address. Until that is supplied this page is not indexed and should not be relied on. Fill it in at the top of inc/legal.php.

No analytics, no advertisingThis site runs no analytics, no tag manager and no advertising or social pixel. Nothing here follows you to another site. One cookie is optional, and you can refuse it.

What cookies are

A cookie is a small file a site asks your browser to keep, and to send back on your next request. It is how a site remembers anything at all between one page and the next, such as what is in your bag. Local storage and session storage do a similar job and are covered here too.

Under the Privacy and Electronic Communications Regulations we need your consent before setting a cookie that is not strictly necessary, or that you have not asked for by using a feature. We do, and the only cookie that needs it is the last one on this page.

Essential cookies

These either keep the shop working or are set because you asked for something by clicking. They cannot be switched off while you use the site, and none of them is used to track you.

Optional cookies

One cookie, off unless you turn it on.

hp_refIf you arrive from an affiliate link, records which affiliate sent you so their commission can be credited if you order. It holds a referral code, not a profile, and it is not used for advertising.30 days

Because we have no consent banner, this one is off by default: if you arrive from an affiliate link and have not turned it on, we simply do not record who referred you. Turn it on in cookie settings if you want the person who referred you to be credited.

Local and session storage

Two keys, both about showing you the right thing quickly. Neither leaves your browser and neither is readable by us.

Other people's cookies

Cloudflare sits in front of this site and sets the two security cookies listed above. We cannot read them and they are not used for advertising. Their purpose is to tell a person from a bot.

Our typefaces are served by Google Fonts, which sets no cookie but does mean your browser makes a request to Google and Google sees your IP address. Nothing else on this site loads from anyone else.

Your choices

The optional cookie is yours to allow or refuse in cookie settings. Turning it off there also deletes it, rather than just stopping it being set again.

Every browser can block or delete cookies too, under its privacy or site settings. Blocking essential cookies will break the bag and the checkout, because those are what the bag and the checkout are made of.

Do Not Track and Global Privacy Control

There is nothing here to opt out of, so these signals change nothing about what this site does. We set no tracking cookie whether your browser sends one or not.

Changes to this policy

The tables above are generated from the site's own cookie list, so they cannot fall out of date without the site changing first. If we add a cookie, it appears here, and anything non-essential will be off until you say otherwise. See also our privacy policy.
