Does Nightfall AI train on your data?
Nightfall's only training statement covers Google Workspace data. What it does with everything else isn't addressed.
This clause is real, but it doesn't resolve the training question - see the finding below.
"Google Workspace APIs accessed through our services are not used for developing, improving, or training our generalized artificial intelligence ("AI") or machine learning ("ML") models."

Why this is still UNCLEAR: The one training sentence in this capture excludes data reached through Google Workspace APIs from developing or training Nightfall's models. That is a narrow carve-out, and a required one: it is a condition of Google's API terms, which is why the same sentence appears in several unrelated policies on this site. Nightfall is a data-loss-prevention product, so it sees a great deal beyond Workspace, and this document says nothing about that content in either direction.

How to opt out of Nightfall AI training
Plan by plan, from what Nightfall AI's own policy says about refusing. Where it publishes the steps, they're listed here with the limits they carry. Where there's nothing to switch off, or nothing graded, this says so instead of inventing a menu path.

Not graded, so no route is pointed at. The one training sentence in this capture excludes data reached through Google Workspace APIs from developing or training Nightfall's models. That is a narrow carve-out, and a required one: it is a condition of Google's API terms, which is why the same sentence appears in several unrelated policies on this site.

Vendor response
We wrote to Nightfall AI on 26 Aug 2026, quoting the clauses above and inviting a correction. Nothing has come back. That's published because a company declining to comment on its own policy is something a reader should know, and because the invitation should be on the record whether or not it's taken up. Any reply goes here, word for word.
