Actually Played vs Game Time Tracker

Actually Played is a free, client-side Minecraft mod that tracks playtime separately for each server and singleplayer world, distinguishing active play from AFK time. After five minutes without qualifying activity, it stops the counter and reclassifies the recently counted idle period as AFK. Signals include movement intent, camera rotation, keyboard or mouse input, and actions such as breaking or placing blocks. Since the mod checks movement intent rather than position, being carried by water or a minecart does not count as active input. It needs no server installation and says it does not communicate with servers. History remains on the user's machine as readable, editable JSON. Sessions stay detailed for 90 days before older records are grouped into monthly summaries. Listed Minecraft versions are 1.7.10, 1.12.2, 1.16.5, 1.20.1 and 1.21.1, with Forge, Fabric or NeoForge support depending on the version. Realms are not tracked because the client lacks a stable identifier. On Minecraft 1.16 and later, settings are edited in a properties file rather than an in-game settings screen.
