Risk classification

•Though Tor encrypts your traffic on its way to the first Tor Relay, and while it travels through the Tor network, it cannot automatically encrypt your connection between the Exit Relay and the website you are visiting.
•Therefore, if you are visiting a site that does not support HTTPS, the Exit Relay operator (who could be anybody) can potentially see everything you send and receive. They might not know who you are, unless there are hints in the traffic itself (which is not uncommon), but they can see everything else.
•So, it is still important to use secured HTTPS web services, even while using the Tor Browser or otherwise connecting to the Tor Network.
