All you ever wanted to know about cookies at this website, but hesitated to ask.
This website doesn't store any cookies apart from those that are required by technology foundation. Such required cookie is the "session id", for example, which is automatically assigned and lives for a few minutes. We don't store nor contain any trackers at our website, except a single Yandex Metrica counter. There are no hostile trackers, like Google tracker.
Other than these automatic temporary cookies, we don't use anything that could track you between sessions, learn your behaviour and ultimately sell you that shiny new robotic cleaner we know you want.
