 - DMS monorepo with FastAPI API + RQ worker (`backend/`) and React + Vite + TypeScript frontend (`frontend/`).
 - Services in `docker-compose.yml`: `api`, `worker`, `frontend`, `db` (Postgres), `redis`, `typesense`.
-- Runtime persistence uses Docker named volumes (`db-data`, `redis-data`, `dcm-storage`, `typesense-data`).
+- Runtime persistence uses host bind mounts under `${DCM_DATA_DIR:-./data}` (`db-data`, `redis-data`, `storage`, `typesense-data`).
 
 ## Project Layout
 - Backend app code: `backend/app/` (`api/`, `services/`, `db/`, `models/`, `schemas/`, `worker/`).

 ## 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
+- `${DCM_DATA_DIR:-./data}/db-data` for PostgreSQL data
-- `redis-data` for Redis data
+- `${DCM_DATA_DIR:-./data}/redis-data` for Redis data
-- `dcm-storage` for uploaded files and app storage
+- `${DCM_DATA_DIR:-./data}/storage` for uploaded files and app storage
-- `typesense-data` for the search index
+- `${DCM_DATA_DIR:-./data}/typesense-data` for the search index
+
+On startup, Compose runs a one-shot `storage-init` service that creates the storage tree and applies write access for the backend runtime user `uid=10001`. If you want to inspect or repair it manually, use:
+
+```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}
 ```
