What a cookie is

A cookie is a small text file stored on your device when you visit a website. Cookies let a site remember that you have been there before and, on some sites, keep you logged in. They do not carry viruses and cannot read other files on your device.

What this site uses

Necessary cookies. Set by the content management system that runs this site. They handle basic functions such as form submission and page display. The site does not work properly without them.
Analytics cookies. We use Google Analytics, which sets cookies beginning with _ga. They record that you visited, which pages you opened and where you came from, so that we can see which product information is worth keeping and expanding. The data is aggregated — we use it to count visits, not to identify individual visitors.

How long they last

Session cookies are deleted when you close your browser. Analytics cookies persist for the period set by Google Analytics, after which they expire on their own.

Turning them off

Every major browser lets you block or delete cookies in its settings, and lets you browse in private mode. If you block necessary cookies, parts of this site may not function. If you block analytics cookies, the site still works normally — we simply stop receiving visit statistics.

Third party

Google Analytics is provided by Google. You can read how Google handles data at policies.google.com/privacy.

Changes

If we start using any other kind of cookie, this page will be updated.
