Cookieless mode

Pass data-cookieless="true" on the tracker script to keep visitor IDs in memory only for the current tab.

data-cookieless="true"

Users in cookieless mode are distinct in-memory visitor IDs. A new tab is a new user. Sessions still use a 30-minute idle timeout inside that tab. Cookieless mode cannot share a user across subdomains. Use this when you need first-party analytics without a stored identifier. Read the cookieless how-to.
