What are cookies?
In the context of the internet at least, a cookie is a small bit of text that a website like ours can send to your web browser when you view a page. If your web browser is set to store cookies it will save it and send it back to us when you view another page on our domain (https://onchan.sch.im).
We do it for a few reasons, so that we can differentiate between the visitor browsing sessions on our site. By giving your web browser a unique session id at the start of your browsing session, we know it's the same person (or at least web browser) when it gets sent back to us on any subsequent pages your visit.
By doing this we are able to show relevant messages to you, take for example when you submit a form on our site, we want to be able to express how grateful we are when the page refreshes.
We also do this to store simple state information, such as whether your device is capable to displaying high resolution images.
There are actually no cookies currently stored in your web browser by our site, meaning you have probably turned off support for cookies. Poor us. You should at least be able to browse the site without problem.
