As Scott McNealy famously
said:
You have no privacy. Get over it.
When you surf the web, you leave your tracks everywhere. For example, your web browser's identification, referring sites and even the IP address and port that your request originated from. This site collects all of this information as normal operating procedure.
This site may set session cookies to improve your browsing experience. Some parts of this site may set permanent cookies to track you when you return to the site or when you visit third-party sites that link to content here.
Additionally, some portions of this site allow you to post information or upload data. Facts about this data (e.g., length, file name, hash digests, etc.) may be logged, but none of the content is intentionally stored.
If you don't like any of this, no one is forcing you to stay. There are plenty of other sites out there with privacy policies just like this one.
