+To disable keychain encryption, set the `keychainEncryption` parameter to `false` when initializing the SDK:
+
+```java
+IterableConfig config = new IterableConfig.Builder()
+    .setKeychainEncryption(false)  // Disable encryption for keychain storage
+    .build();
+
+IterableApi.initialize(context, apiKey, config);
+```
