NotebookLM can summarize and organize source files, but convenience should not decide whether a document is safe to upload. Google’s privacy page explains an important distinction: content in NotebookLM is not used to directly train Google’s foundational AI models unless you choose to provide feedback. If you send thumbs-up or thumbs-down feedback, the associated prompts, sources and outputs may be collected for review.
What the feedback rule means
Google says feedback content can be reviewed by specially trained teams, used to improve products and retained for up to three years after being disconnected from the Google Account. The page describes different handling for qualifying Google Workspace or Workspace for Education accounts. Your organization’s contract and policies may also apply.
That does not mean every uploaded consumer document is automatically public. It does mean you should understand the service and account terms before adding confidential material. Do not upload customer records, credentials, source code, unreleased designs, student data or personal documents unless you have permission and your employer or school has approved the service.
A safer way to test the feature
Start with a public report, your own non-sensitive notes or a document with identifying details removed. If you submit feedback, avoid attaching confidential prompts or files. For work or school accounts, confirm which NotebookLM edition your administrator enabled and what protections apply rather than assuming consumer and managed accounts are identical.
Bottom line: Check the current privacy terms before uploading, and be especially deliberate about what is included with product feedback. AI study tools are useful; data classification still belongs to you and your organization.
