Of course, you might like the idea of all these powerful AI features but not be comfortable with having to send some of your personal data off-device for processing. If that's the case, Samsung has also included a single toggle that disables off-device processing of Galaxy AI data, but leaves as many of the features mentioned here intact, and as functional as possible.
To disable off-device processing, just go to Settings > Advanced Features > Advanced Intelligence > turn the 'Process data only on device' toggle on.
