A transit prediction site can potentially gather a lot of personal information, like your where and when you travel and your location within a block. TransSee is set up not to collect personal information. Standard web server logs are disabled, but errors are still logged. Most logging is done by month and transit agency. For example User Agent, transit stop and the first 3 bytes of the IP address are logged by month and agency, but each log is separate. There is a hit count by agency and hour of the week.
