Android Auto Gemini privacy settings worth checking before passengers get in

Gemini in the car now reads your personal data

Google began rolling out Personal Intelligence for Gemini on Android Auto on 20 October, according to Android Police. With permission, the assistant can draw on Gmail, Google Calendar, Google Photos, Maps, YouTube and Search to answer questions while you drive.

The feature is aimed at solo drivers. Android Police gives examples such as asking Gemini for a flight gate from a confirmation email, routing to an appointment stored in your calendar, or starting directions to a place you once photographed.

The publication raises a practical concern: the assistant cannot tell whether you are alone or carrying passengers. Anyone in the cabin is close enough to the microphone to speak to it, so personal details could surface in front of other people.

Check whether the feature applies to you

Personal Intelligence is restricted before you reach any settings. It works only on personal Google accounts held by people aged 18 or over. Workspace business, enterprise and education accounts are excluded.

Location matters too. Android Police reports that the feature is unavailable in the European Economic Area, Switzerland, the UK and Nigeria. Drivers in those regions, or on work and school accounts, will not see the setting yet.

Android Auto is receiving the rollout now. Cars with Google built in are next, with the feature expected over the coming months.

One detail is easy to miss. Personal Intelligence stays off until you enable it, but if you have already switched it on in the Gemini app on your phone, that choice carries over to the car.

Turn it off or trim the connected services

The simplest step is to switch the feature off entirely. Android Police describes the path in the Gemini app: open the menu, go to Settings and help, then Personal Intelligence, and disable the main toggle.

The site notes this is less drastic than it sounds. Navigation, music, calls and general questions keep working. What disappears is personalisation, because Gemini stops consulting your account data for context.

A middle option exists in the Connected Apps menu, reached through the same Personal Intelligence settings screen. There you can decide which individual services Gemini may access.

Android Police flags one entry as easy to overlook. Google Workspace appears as a single app, yet it bundles Gmail, Google Calendar, Google Drive, Google Keep and Google Tasks behind one switch, so email and schedule cannot be separated. The writer says he turned his off.

He also recommends disabling Google Photos, arguing that a vague spoken prompt could reveal where his pictures were taken. He would keep Maps and YouTube enabled, since past destinations, saved places and watch history make route planning and music suggestions more useful.

Voice Match and message settings add further protection

Voice Match is Google's voice recognition feature, which tunes the assistant to respond mainly to your voice. Android Police calls it the best defence against passengers waking the assistant, while admitting it is imperfect and occasionally confused in his experience. Retraining it reduces the chance of someone else triggering it by accident.

To retrain, open the Gemini app, tap your profile picture, go to Settings, then Talk to Gemini hands-free, and retrain the voice model. On some phones the menu is still labelled Hey Google and Voice Match.

Not every risk involves artificial intelligence. By default, Android Auto shows incoming messages on the car's display and reads them aloud using text-to-speech, which converts text into spoken audio. With passengers on board, your private texts appear on a large screen and play through the car speakers.

Android Police suggests two changes in the Android Auto settings on your phone, under Notifications. Turning off Show message notifications stops the dashboard pop-ups. Turning off Notifications with Assistant stops messages being read aloud.

Why a short check matters

Android Police frames the whole exercise as a five-minute review before your next shared drive. The advice matters most for drivers who enabled Personal Intelligence on their phone without realising it extends to the car.

The settings described come from Android Police's reporting and reflect its writer's own preferences, such as keeping Maps on and Photos off. Google has not been quoted in the report on passenger privacy specifically, so drivers should treat the suggested combinations as guidance rather than official recommendations.

For anyone in an eligible region with a personal account, the practical takeaway is straightforward: decide which services Gemini may consult, tune Voice Match, and consider hiding message notifications before the next trip with company in the car.
