Does Gemini app (personal Google account) train on your data?

Personal plan Google · Assistant · Last verified

Trains by default

Trains on business data unless you opt out.

Short answer: Yes, opt-out

Personal Google accounts (18+): Keep Activity is on by default, and with it on Google uses your chats to train generative AI models, with help from human reviewers. Audio and Gemini Live video/screenshares are not used by default.

Why this matters: Data used for training can't be pulled back out of a trained model, so opting out only protects what comes after. Why training matters →

Can you turn training off?

Yes (turn off Keep Activity)

Turning off Keep Activity stops future chats being used for training unless you send feedback. It also turns off chat history and some Connected Apps. There is no separate training-only toggle on the pages checked.

Data retention

Auto-delete after 18 months (default); 72 hours with Keep Activity off

Auto-delete can be set to 3 or 36 months, or off. With Keep Activity off, chats are still kept 72 hours.

Source:

Retention after you delete

Human-reviewed chats kept up to 3 years even after you delete

Deleting activity does not delete chats already sent to reviewers. Those are disconnected from your account.

    “Chats reviewed by human reviewers (and related data like your language, device type, location info, or feedback) are not deleted when you delete your activity. Instead, they are retained for up to three years.”

Human review of chats

Yes

A subset of chats is reviewed by humans, including service providers, to improve Google services. Turning off Keep Activity stops this for future chats, but review for safety/abuse continues even with it off or in temporary chats.

Keep in mind

  • Chats are still kept 72 hours with Keep Activity off.
  • Chats already human-reviewed are kept up to 3 years even after deletion.
  • Sending feedback with Keep Activity off still sends that conversation for review and improvement.
  • Some Connected Apps stop working when Keep Activity is off.
