 ## Privacy
 
-The SDK is recording and aggressively redacting all text and images. We plan to add fine controls for redacting, but in this version, we just allow either on or off. The default is on. Please don’t turn it off if you have sensitive data in your app. Before the Beta is complete, we'll give you the controls you need.
+The SDK is recording and aggressively masking all text, images and webviews. Please don’t turn it off if you have sensitive data in your app.
+However, if you're working on a mobile app that's free of PII or other types of private data, you can opt out of the default text and image masking settings. To learn more about Session Replay privacy, [read our docs](/platforms/android/session-replay/privacy/).

+<Alert>
+
+Using custom masking in your Session Replays may accidentally expose sensitive customer data. Before publishing an App with Session Replay enabled, make sure to test it thoroughly to ensure that no sensitive data is exposed.
+
+</Alert>
+
+By default, our Session Replay SDK masks all text content, images, webviews, and user input. This helps ensure that no sensitive data is exposed. You can also manually choose which parts of your app's data you want to mask by using the different options listed below.
+
+To disable the default masking behavior (not to be used on applications with sensitive data):
+
+```javascript
+Sentry.mobileReplayIntegration({
+  maskAllText: false,
+  maskAllImages: false,
+  maskAllVectors: false,
+}),
+```
+
+_Make sure your Sentry React Native SDK version is at least 5.36.0 or 6.3.0._
+
+## Mask and Unmask Components
+
+You can choose which views you want to mask or unmask by using the `Mask` or `Unmask` components.
+
+```jsx
+import * as Sentry from '@sentry/react-native';
+
+const Example = () => {
+  return (
+    <View>
+      <Sentry.Unmask>
+        <Text>This will be unmasked</Text>
+      </Sentry.Unmask>
+      <Sentry.Mask>
+        <Text>This will be masked</Text>
+      </Sentry.Mask>
+    </View>
+  );
+}
+```
+
+## General Masking Rules
+
+When components are wrapped by `Unmask`, **only direct children will be unmasked**. You'll need to explicitly wrap each further child if you want them to appear in the replay.
+
+```jsx
+<Sentry.Unmask>
+  <Text>
+    This will be unmasked
+    <Text>
+      This will be masked
+    </Text>
+  </Text>
+  <Text>
+    This will be unmasked
+  </Text>
+</Sentry.Unmask>
+```
+
+When components are wrapped by `Mask`, **all children will be masked**.
+
+```jsx
+<Sentry.Mask>
+  <Text>
+    This will be masked
+    <Text>
+      This will be masked
+    </Text>
+  </Text>
+  <Text>
+    This will be masked
+  </Text>
+</Sentry.Mask>
+```
+
+### Masking Priority
+
+If a view is marked as masked, it will always be masked, even if it's a child of an unmasked view.
+
+```jsx
+<Sentry.Mask>
+  <Text>This will be masked</Text>
+  <Sentry.Unmask>
+    <Text>This will be masked</Text>
+  </Sentry.Unmask>
+</Sentry.Mask>
+```
+
+The `Mask` component can't be unmasked.
+
+```jsx
+<Sentry.Unmask>
+  <Sentry.Mask>
+    <Text>This will be masked</Text>
+  </Sentry.Mask>
+</Sentry.Unmask>
+```
+
+## Troubleshooting
+
+The `Mask` and `Unmask` components are native components on iOS and Android and are compatible with both the New Architecture and the Legacy Architecture.
+
+The masking components behave as standard React Native `View` components.
+
+If you are experiencing issues with unmasking more than one level deep, check if the wrapped components are present in the native views hierarchy. If not your view were evaluated by React Native to be flattened. Read more about [flattening views](https://reactnative.dev/architecture/view-flattening) in the React Native documentation.
