+Manage mobile app log attachments
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Use ``/mobile-logs`` to enable an attachment option in the Mattermost mobile client that lets users attach their mobile app logs as a file to the message being sent. This helps administrators and support engineers debug mobile-specific issues by providing device-side context that isn't available from server logs alone. The command updates the ``attach_app_logs`` advanced preference and always responds with an ephemeral message visible only to the invoking user.
+
+.. note::
+
+    This command requires Mattermost mobile app v2.38 or later. On earlier versions the preference can still be set, but the attachment option won't appear in the mobile client.
+
+- Enable log attachment for yourself using ``/mobile-logs on``.
+- Disable log attachment for yourself using ``/mobile-logs off``.
+- Check your current setting using ``/mobile-logs status``.
+- System admins can manage the setting for another user by appending a username, such as ``/mobile-logs on @username``, ``/mobile-logs off @username``, or ``/mobile-logs status @username``.
+
+.. note::
+
+    Non-admin users can only manage their own preference. Attempts to target another account return a neutral *Unable to change mobile log settings for that user* message to avoid username enumeration. Preference changes made through this command are recorded in the audit log.
