Avoid uploading data you are not allowed to share. This can include passwords, API keys, private customer data, medical records, legal files, financial records, unreleased business plans, and confidential source code.
In practice
Some AI tools offer enterprise controls, data processing terms, retention settings, or local deployment. The right choice depends on the sensitivity of the data and the rules your organization must follow.
What to watch
When unsure, do not paste the data. Redact, summarize, use approved tools, or ask the responsible security or legal owner first.
