+### Disabling Analytics
+
+You can disable analytics:
+
+```typescript
+import { init } from "create-better-t-stack";
+
+const result = await init("my-private-project", {
+  yes: true,
+  disableAnalytics: true, // No analytics data will be sent
+  frontend: ["tanstack-router"],
+  backend: "hono",
+});
+```
+
+> **Note:** Analytics help improve Better-T Stack by providing insights into usage patterns. When disabled, no data is collected or transmitted.
