 <p>As part of its multiplayer API, SMAPI transmits basic context to players you connect to (mainly your OS, SMAPI version, game version, and installed mods). This is used to enable multiplayer features like inter-mod messages, compatibility checks, etc. Although this information is normally hidden from players, it may be visible due to mods or configuration changes.</p>
