Does NotebookLM train on your data?

Yes

Google · Search

No. NotebookLM does not train its models on your content by default, and its business tier (None of the consumer or Workspace-core tiers carry HIPAA, SOC or ISO coverage. Only NotebookLM Enterprise, a separate Google Cloud SKU with its own IAM, VPC-SC and CMEK controls, targets regulated use.) keeps your data out of training.

What we checked

This assessment separates the consumer product from any business plan. It uses the vendor documents linked below; an unverified item is not a pass.

Default data training: No by default; Google states uploads, queries and responses are not used to train generative AI models, on consumer or Workspace and Education accounts alike. Consumer thumbs up or down feedback can get de-identified human review.
Business-tier training: No by default; None of the consumer or Workspace-core tiers carry HIPAA, SOC or ISO coverage. Only NotebookLM Enterprise, a separate Google Cloud SKU with its own IAM, VPC-SC and CMEK controls, targets regulated use. is the business tier recorded for this profile.
Training control: Not verified; No reliable training opt-out was confirmed in the sources reviewed for this profile.

Practical risk: NotebookLM does not train on your uploads or queries on either tier, a genuinely strong default. But Google is explicit that the product carries no SOC 2, ISO 27001 or HIPAA BAA today; for regulated data you would need the separate NotebookLM Enterprise product.

How to make a decision

Check the precise account tier, written contract and intended data before approving NotebookLM. A security certification, DPA or setting can apply to only part of a vendor's service. Keep the source links with your supplier review and revisit them when the vendor changes its terms.
