 ## Uptime snapshots
 
 The production server samples uptime every 30 minutes and exposes the history at
-`/api/uptime`. Set `DATABASE_URL` or `UPTIME_DATABASE_URL` to persist snapshots
-in Postgres:
+`/api/uptime`. Snapshots are stored in SQLite under `~/tsswebstorage` by
+default. Set `UPTIME_STORAGE_DIR` to choose a different folder:
 
 ```sh
-DATABASE_URL=postgres://user:password@127.0.0.1:5432/tssbot
+UPTIME_STORAGE_DIR=~/tsswebstorage
+UPTIME_DATABASE_FILE=uptime.sqlite
 UPTIME_SAMPLE_INTERVAL_MS=1800000
 UPTIME_HISTORY_LIMIT=336
 ```
 
-The server creates the `uptime_snapshots` table automatically. Without a
-database URL, uptime sampling still runs but only the latest in-memory snapshot
-is available.
+The server creates the storage folder, SQLite database, and `uptime_snapshots`
+table automatically.
