If you only read the Temeraire wiki website, no more information is collected than is typically collected in server logs by web sites in general.
If you contribute to the Temeraire wiki, you are publishing every word you post publicly. If you write something, assume that it will be retained forever. This includes articles, user pages and talk pages. Some limited exceptions are described below.
To maintain the integrity of the information on the site, users who wish to participate in editing are required to create a user account. Creating an account requires a valid e-mail address. Strong passwords are recommended. Once created, user accounts will not be removed.
Due to the requirements of federal law, children under 13 are not permitted to create user accounts.
Any information a user places in their profile (Your User:Username page) is optional and public.
Removing text from the wiki does not permanently delete it. In normal articles, anyone can look at a previous version and see what was there. If an article is "deleted", any user with "administrator" access on the wiki, meaning almost anyone trusted not to abuse the deletion capability, can see what was deleted. Information can be permanently deleted by those people with access to the servers, but there is no guarantee this will happen except in special circumstances.
The Temeraire wiki does not sell or share private information, such as email addresses, with third parties, unless you agree to release this information, or it is required by law to release the information.
Upon logging in, the wiki will set a temporary session cookie (PHPSESSID) whenever you visit the site. More cookies may be set when you log in, to avoid typing in your user name (or optionally password) on your next visit. These last up to 30 days. You may clear these cookies after use if you are using a public machine and don't wish to expose your username to future users of the machine. (If so, clear the browser cache as well.)
Every time you visit a web page, you send a lot of information to the web server. Most web servers routinely maintain access logs with a portion of this information, which can be used to get an overall picture of what pages are popular, what other sites link to this one, and what web browsers people are using. The Temeraire wiki does not use this information to keep track of legitimate users.
The Temeraire Wiki may update this policy from time to time.
