The main website (www.ntppool.org / www.pool.ntp.org) doesn’t set any browser cookies. Some access logs are generated strictly for diagnostics purposes. No long term storage or analytics on user behavior is attempted.
The manage website (manage.ntppool.org) sets a cookie on login to track authentication. The site also keeps a record of the account information you provide and NTP server IPs that are registered. We try hard to not keep any information that’s not essential for operating the system.
