What zero data retention means, where your files live, and the clauses to ask for.
Where your data goes
With enterprise agreements, your prompts and files are processed and then discarded. They are not used to train public models.
Where it lives
Documents can stay in your own Microsoft or Google tenancy. The AI reads them in place, with the same permissions your staff have.
What to put in the contract
A data processing agreement, a zero-retention clause and the right to an audit log.
