Tor hides your location from destination servers, but it does not encrypt <i>all</i> your communication. The last relay of a Tor circuit, called the <i>exit node</i>, establishes the actual connection to the destination server. This last step can be unencrypted, for example, if you connect to a website using HTTP instead of HTTPS.
