Analytics records a random browser ID, session times, active playtime, device/browser/OS categories, controls, and completed tower purchases and upgrades. Active time stops while hidden, paused, or after two minutes without input. Testing is flagged separately. No names, typed text, raw IP addresses, or raw user-agent strings are added to gameplay analytics. Turn sharing off to stop collection.

The horde test replaces this run with 1,000 continuously replenished enemies until you end the test, a randomized garrison, 2,800 gold, and an unbreakable gate. Use the live counter to inspect performance.
