 ## Where Your Data Is Stored
 
-LedgerDock stores data in Docker volumes so it survives container restarts:
+LedgerDock stores persistent runtime data in host bind mounts. By default the host root is `./data`, or set `DCM_DATA_DIR` to move it:
 
-- `db-data` for PostgreSQL data
-- `redis-data` for Redis data
-- `dcm-storage` for uploaded files and app storage
-- `typesense-data` for the search index
+- `${DCM_DATA_DIR:-./data}/db-data` for PostgreSQL data
+- `${DCM_DATA_DIR:-./data}/redis-data` for Redis data
+- `${DCM_DATA_DIR:-./data}/storage` for uploaded files and app storage
+- `${DCM_DATA_DIR:-./data}/typesense-data` for the search index
 
-If you switch to host bind mounts (for example under `./data/`), create those directories and grant write access to container runtime user `uid=10001` for backend storage paths.
+Before first run, create storage and grant write access to container runtime user `uid=10001`:
+
+```bash
+mkdir -p ${DCM_DATA_DIR:-./data}/storage
+sudo chown -R 10001:10001 ${DCM_DATA_DIR:-./data}/storage
+sudo chmod -R u+rwX,g+rwX ${DCM_DATA_DIR:-./data}/storage
+```
 
 To remove everything, including data:
 
 ```bash
-docker compose down -v
+docker compose down
+rm -rf ${DCM_DATA_DIR:-./data}
 ```
 
 Warning: this permanently deletes your LedgerDock data on this machine.
