Matches come from the open Deadlock API database. New games reach it with a delay — sometimes hours or days.
You can speed this up with the official Deadlock API Ingest app: it runs in the background while you play and submits your match IDs to the database. Your games then appear here almost immediately — and your friends’ too.
This is a third-party app by the Deadlock API authors, not LOCKSTAT. It reads the Steam cache and game memory (read-only, no game modification), and while the game is closed it uses your saved Steam login to request your friends’ new matches. Uninstall it in Settings → Apps.
