What happens to your data?

Google collects your prompts, uploads, and interactions to provide and improve its services, including training AI models. Some data is reviewed by human contractors to improve safety and quality, and your data may be shared with connected apps or third-party services you authorize.

Does it train on your data?

User data is used to train generative AI models unless the 'Keep Activity' setting is turned off or the user engages in temporary chats.

Can you opt out?

Yes, you can turn off the 'Keep Activity' setting to prevent your future chats from being used to train AI models or being reviewed by humans.

Data retention

Default auto-delete is 18 months, configurable to 3, 36 months, or indefinite. Human-reviewed chats are retained for up to 3 years. Temporary chats/Keep Activity off data is retained for 72 hours.

Encryption & security

Not specified.

Is it safe for work?

Not recommended for sensitive or confidential business information, as human reviewers may access your chats and data is used for model improvement by default.
