Does Box train on your data?
Box's AI FAQ answers what its blocked privacy policy cannot be asked: neither Box nor its model providers train on customer data, and any future custom training would need explicit approval.
No opt-out found in this policy
"Box's model providers do not train on any data that they receive from Box. Box also does not train AI models based on customer data."

How we read it: Resolved from UNCLEAR on 10 September 2026. The privacy policy has served a challenge page to every reader since early September, so the answer comes from the Box AI FAQ in the support centre, undated. Both halves are there, Box's own models and its providers', with the future carved out honestly: custom-trained models on a customer's content, if ever offered, would need that customer's explicit approval. Customers can also switch Box AI off. B because it is an undertaking.

How to opt out of Box AI training
Plan by plan, from what Box'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.

Nothing to switch off: Box's policy says training is off here.
What this policy has done since we started watching
The record starts here. Box's 3 documents were first captured on 6 Sept 2026, and there's no earlier copy to compare them against, so this verdict has no history behind it yet. From now on every re-read is diffed against those copies, and anything that moves appears here.
Vendor response
We haven't yet written to Box about this verdict, and they haven't disputed, clarified or announced a change to any clause quoted above. When either happens it's published here, word for word.

Box is graded B, and a company that's earned that can say so with the verdict itself. The image below links back to this page and shows the live grade. If the grade changes, the badge changes the same day, wherever it's embedded. It's free and it isn't for sale.
