Letting us (the 4CAT developers at the Digital Methods Initiative) know that you have installed 4CAT is optional but greatly appreciated as it helps us justify and find funding for on-going development.

We only store the data you enter, and the approximate geographic location of the IP address it is sent from (but not the IP address itself). This is a one-time 'ping': no information will be sent during later 4CAT usage. You can check our website for more information on what we do with this data.
