# Delete Local Session Data

Delete all local user data that was collected during onboarding from the device by calling `deleteLocalUserData`. This method removes session-scoped data only; it does not affect locally stored identities added via `addFace` or `setFaces` for 1:N `FaceAuthMode.local` Face Login.

Use this method after onboarding completes to clear session data on the device, or when complying with data retention requirements.

## When to call deleteLocalUserData

Do not call `deleteLocalUserData` before `finishFlow()`. Calling it before `finishFlow()` will prevent the onboarding session from completing.

- **After startOnboarding, startFlow, or startWorkflow**: Call `deleteLocalUserData` after the user completes all steps in the flow. It is safe to call this method in the body of or after any of these callbacks: `onSuccess`, `onError`, and `onUserCancelled`.
- **After startNewOnboardingSection**: If you are using section-based flows, do not call `deleteLocalUserData` between sections or modules. Call it only after the user has completely finished the custom flow, and only after `finishFlow()`.

## Delete local user data

```dart
await IncodeOnboardingSdk.deleteLocalUserData();
```

`deleteLocalUserData` is asynchronous but returns no result. Your app can `await` the call to know when the deletion has completed, but there is no success or failure value to check and no error conditions to handle.
