-CuraFrame stores users and evaluation logs in a SQLite database. On Render.com you **must** use a [Persistent Disk](https://render.com/docs/disks) so the database survives service restarts and redeploys. The included `render.yaml` already configures this automatically — here is what it does and how to set it up step-by-step:
+CuraFrame stores users and evaluation logs in a managed PostgreSQL database. The included `render.yaml` provisions all services automatically — here is what it configures and how to deploy:
 
 1. **Connect your repo to Render.com**
    - Go to [render.com](https://render.com), sign in, and click **New → Blueprint**.
    - Select the CuraFrame repository. Render will detect `render.yaml` and provision the services automatically.
 
 2. **What `render.yaml` configures**
-   - A **web service** (`curaframe-web`) running on the **Starter plan** (required for persistent disk support).
-   - A **1 GB persistent disk** mounted at `/data` — the SQLite database is stored at `/data/curaframe.db` and survives restarts.
-   - `CURAFRAME_DB=/data/curaframe.db` — tells the app where to find/create the database.
+   - A **managed PostgreSQL database** (`curaframe-db`) on Render's free database plan (PostgreSQL 18).
+   - A **web service** (`curaframe-web`) on the **Starter plan**, with `DATABASE_URL` injected automatically from the managed database.
    - `CURAFRAME_SECURE_COOKIES=1` — marks session cookies as `Secure` (required for HTTPS on Render).
-   - A second **web service** (`curaframe-console`) running the Streamlit console on the free plan (no database needed).
+   - A second **web service** (`curaframe-console`) running the Streamlit console on the free plan, also connected to the database.
 
-3. **Why the free plan is not enough for the web service**
-   - Render's free tier does **not** support persistent disks. A database file written to the default filesystem (`/opt/render/project/src/`) is **ephemeral** — it is wiped every time the service restarts, which means all registered users and logs would be lost. The Starter plan (~$7/month) is the minimum that supports a persistent disk.
+3. **Required secret (set manually in Render dashboard)**
+   - `JWT_SECRET` — a cryptographically random secret used to sign authentication tokens. Generate one with:
+     ```bash
+     python -c "import secrets; print(secrets.token_hex(32))"
+     ```
+     Add it as an environment variable on the `curaframe-web` service before the first deploy.
 
 4. **Manual setup (if you prefer not to use the Blueprint)**
    - Create a **Web Service** with environment `Python`, build command `pip install -r requirements.txt && pip install -e .`, and start command `uvicorn apps.web.main:app --host 0.0.0.0 --port $PORT`.
-   - In the service settings, go to **Disks → Add Disk**, set the mount path to `/data` and size to `1 GB`.
-   - Add the environment variables `CURAFRAME_DB=/data/curaframe.db` and `CURAFRAME_SECURE_COOKIES=1`.
+   - Create a **PostgreSQL** database on Render and link it to the web service via `DATABASE_URL`.
+   - Add environment variables `CURAFRAME_SECURE_COOKIES=1` and `JWT_SECRET` (see above).
 
 The database tables (`users`, `logs`, `form_submissions`) are created automatically on first startup — no manual schema migration is required.
