We generate a daily changing identifier using the visitor’s IP address and User Agent. To anonymize these datapoints, we run them through a hash function with a rotating salt.

hash(daily_salt + website_domain + ip_address + user_agent)

This generates a random string of letters and numbers that is used to calculate unique visitor numbers for the day. Old salts are deleted to avoid the possibility of linking visitor information from one day to the next.
