+Config option `delete_stale_devices_after`
+
+An optional duration. If set, Synapse will run a daily background task to log out and
+delete any device that hasn't been accessed for more than the specified amount of time.
+
+Defaults to no duration, which means devices are never pruned.

+Example configuration:
