## Purging unused data with synapse-janitor
**NOTE**: There are [reports](https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/465) that **synapse-janitor is dangerous to use and causes database corruption**. You may wish to refrain from using it.
When you **leave** and **forget** a room, Synapse can clean up its data, but currently doesn't.
This **unused and unreachable data** remains in your database forever.
