Ending an AI Assistant's Access

If you have approved an outside AI assistant to work in your account, you can end that access at any time from your account settings. It stops immediately and this platform sends it nothing further. Studies it already produced remain yours. Anything you already shared in the assistant’s own chat is kept under that provider’s terms. If you delete your account, every approval and every record tied to a connected assistant is removed with it.

Using an AI Assistant

• You are responsible for the assistants you approve and for what you ask them to do in your account.
• Only figures this platform calculated are Six Sigma Center results. A summary, chart or document an assistant writes on its own is not a Six Sigma Center report, even if it uses this name.
• Studies an assistant runs count toward your plan exactly as your own do, and only what your plan includes is available to it.
• When a request cannot be calculated, the platform says why instead of guessing. A refusal is a result, not a failure of the service.
• Your use of an assistant is also governed by that provider’s own terms and privacy policy, which I do not control.

8. Limitation of Liability
