Starting with Android 12 (API level 31), the android:allowBackup="false" attribute is ignored for device-to-device (D2D) transfers. To ensure that application data is not transferred or backed up on modern Android versions, you should also implement android:dataExtractionRules in the <application> tag. This provides more granular control over what data is included in backups and transfers, which is especially important for apps handling sensitive messaging data.
