Cookies are short bits of information that are stored and retrieved from your browser. For example, if you choose your preferred language, a cookie would store it in your browser so you don’t have to choose it every time you visit a page of the same website.

The cookies we create are temporary. Besides the basic ones that let us store your site preferences, some let us analyze site behaviour and some let us determine the impact of our advertising. That is, which types of ads are working and which types are not.

These cookies are essential for proper site function. They include things like the language you prefer, the country your IP address is from (so you can view the correct version of the page), and whatever cookie preferences you choose here.

These cookies help us understand behavior on our website and are critical to help us see which of our advertising and marketing efforts are working.

We advertise on a variety of platforms including social media and internet search providers. These sorts of cookies and the information we share lets platforms match you with your social media or internet search account (we can't see that information, only the platform can). That's helpful because it allows the platform to indicate whether our ads resulted in purchases or not. Then we can optimize the way we serve ads so that we aren't wasting money on ineffective ads. The platform also isn't driving you crazy with completely irrelevant ads. This doesn't make you get any more ads, it just makes the ads more relevant to you.
