Does the other driver need the app, and will they know they're being monitored?

The other driver doesn’t need the app and doesn’t have to do anything. Sentry Driver is an owner-only app — they install nothing, set up nothing, and don’t change how they drive.

Monitoring happens through the vehicle’s own data via Tesla’s official Fleet API, not through anything on the other person’s phone. Because of that, the app itself doesn’t announce to them that monitoring is active.

That makes telling them your job — and our Terms require it: let anyone you allow to drive the car know that its location and driving events are recorded and shared with you. For a teen or family member, a quick heads-up is enough. If the car belongs to an employer, or you’re monitoring a minor, extra laws may apply. This isn’t legal advice.
