- If you are only reading this wiki, the only information collected is what is normally collected in server logs.
- If you write something on this wiki, it's here to stay and will be associated with either your user name or IP address.
- If you do not create an account, or fail to log in before editing, your IP address is recorded and made available to everyone reading that edit. That is why it is recommended you create an account and remember to always log in before editing.
- If you are logged in with an account then only the information you volunteer about yourself, and your identity, will be made available.
- Explain xkcd does not sell any information about its users to anyone.
