How to check Grok in your own company
- 01Find out which plan each account is on. The vendor's terms differ between Grok for individual users and Grok Business, Enterprise and API. People who signed up with a personal address are on the personal terms, whatever the company bought.
- 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.
- 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.
- 04Compare with your contract or order form. Where a data processing agreement or negotiated terms exist, they take precedence over the public pages.
- 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.
What to ask the vendor
Neutral questions for the points the vendor's public pages left open. Ask for the answer in writing.
- 01On the plan we hold, are our prompts, files and outputs used to train or improve models? Which contract clause says so?
- 02How long are prompts, files and outputs kept by default, and can an administrator shorten that period?
- 03Is a zero-retention option available on our plan, and what does it exclude (for example abuse monitoring logs)?
- 04How do we request deletion of our data, and within how many days is it completed, including backups?
- 05Can your staff or contractors read our inputs? In which cases, and is that access logged?
- 06Is single sign-on available on our plan, and can sign-in with personal accounts be blocked for our domain?
- 07Is SCIM provisioning available, so that leavers lose access automatically?
- 08Are audit logs available to administrators, and can they be exported to our security tooling?
- 09Is there an administrator console where data controls can be set for every account in our organisation?
- 10Do the statements on your public pages apply to our contract as written, or do negotiated terms override them?
