+### Screenshot Masking (Android)
+
+On Android, you can configure masking to automatically redact sensitive content like text and images from error screenshots. Masking is enabled by default.
+
+```javascript
+Sentry.init({
+  dsn: "___PUBLIC_DSN___",
+  attachScreenshot: true,
+  screenshot: {
+    maskAllText: true, // default: true
+    maskAllImages: true, // default: true
+  },
+});
+```
+
+<Note>
+Screenshot masking on Android requires the `sentry-android-replay` module at runtime. This is included automatically when using the Sentry React Native SDK.
