How to check Claude in your own company

  1. 01Find out which plan each account is on. The vendor's terms differ between Free, Pro and Max (personal accounts), Claude Team and Claude Enterprise. People who signed up with a personal address are on the personal terms, whatever the company bought.
  2. 02Open the account or administrator settings and look for the data-controls or model-training setting the vendor's page describes. Note what it is set to today and who is able to change it.
  3. 03Read the vendor's own page, linked under each fact below, and check that the sentence quoted here is still there. Pages change; the date shows when this one was read.
  4. 04Compare with your contract or order form. Where a data processing agreement or negotiated terms exist, they take precedence over the public pages.
  5. 05Record the plan, the setting and the date in your AI inventory, so that the answer exists the next time a customer or auditor asks.
