Does Google Gemini train its models on your data?
It depends — Google Gemini trains on consumer/free-tier data by default but excludes business, enterprise and API tiers.
Consumer Gemini Apps activity is on by default, can be sampled by human reviewers and used to improve Google's services; Workspace with Gemini and enterprise accounts are not used for training and are not human-reviewed.
Can you opt out?
On a personal Google account, turn off "Gemini Apps Activity" to stop future conversations being used to improve Google's services. Note: conversations already sampled for human review are kept up to 3 years and are not deleted when you delete your activity. Workspace/enterprise accounts have these protections by default.
Zero retention / DPA
Workspace with Gemini gives enterprise-grade data protection: prompts and responses are not used to train models outside your domain and are not reviewed by humans. Consumer Gemini has no zero-retention option — activity is retained 18 months by default (admin-configurable on work/school accounts). DPA ↗
