Gemini documents its data practices in detail and gives users named controls over activity, retention and training, but the content licence it takes is sublicensable and lasts as long as the content is protected, chats train Google's models unless the user turns a setting off, and several user rights are framed as conditional or tied to European law.

What Gemini's privacy policy and terms of service say about your data

Trains on chats by default

Activity is used to develop and improve Google services including training generative AI models, and stopping that requires the user to turn off the Keep Activity setting.

Broad content licence

The terms take a worldwide, royalty-free licence that Google may sublicense to contractors and other users, lasting as long as the content is protected by intellectual property rights.

Retention measured in months

Gemini Apps activity auto-deletes after a default of 18 months, changeable to 3 or 36 months or off, while chats seen by human reviewers are kept up to three years and are not removed when activity is deleted.

No certification or privacy contact

The policy names encryption in transit and account security features but no security certification, audit, or named data protection officer.

What the policy is silent or vague on

Not stated: your ownership of generated outputs
Not stated: a sub-processor list or data processing agreement
Not stated: marking of AI-generated output
Not stated: a certification or privacy contact
