Cookies are small text files that a website stores on your device and reads on later visits. They allow a site to remember information between page requests, such as your preferences or the state of a session. Similar technologies, including local storage, work in comparable ways and are covered by this policy.
That memory is what keeps a session from resetting on every click, and it is also what lets a site recognise a returning visitor. It matters to know that a cookie is not a program. It cannot run code, read other files on your device, or reach into other websites — it only carries the small piece of information the site itself placed there. Where a cookie is set, it belongs to a domain, and that domain determines which site may read it again.
On techpeak.digital we keep the number of cookies low and the categories narrow, so each one can be explained in plain language. The categories below describe every kind of cookie you can encounter on this site.
