What Are Cookies?
Cookies are small text files that a website stores on your device when you visit it. They help the site remember certain details about your visit — such as your preferences or whether you have seen a particular notice — so that it can serve you more consistently on future visits.
Cookies do not contain personal information on their own, and they cannot run programmes or carry viruses. They are a routine part of how most websites function.
We use cookies on the Khit Lab website to keep the site working reliably, to understand how it is being used, and to remember your settings between visits. We will always ask for your consent before placing any optional cookies on your device.
