Logs are reports created from the data that is generated by actions in learn.gold. Every action you make in learn.gold is logged. Tracking is just recording things that can be recorded, mouse clicks on links, responses to questions, saving text input (forums, form fields) grades and so on. It isn't sinister, it just means that you see the courses you are enrolled on or what assessments are due or any messages you may have been sent.
Everybody has access to their logs, they are in your profile > Administration > Activity reports.
