OpenAI Adds Advertising Data Collection to ChatGPT's Free Tier

On July 13, the Frontier Watch policy monitor flagged a change to OpenAI's consumer privacy policy. The document's effective date had moved from May 18 to June 4, 2026, and roughly a third of the text was new.

The substance is a new category of data collection called "Ads data." The policy now reads: "For Free and Go users, subject to your choices and controls, we collect information about your ads history and interests, such as the types of ad content that you view or engage with."

No advertising category existed in the previous version. The phrase "Ads data" appears four times in the new text and zero times in the old. Advertising has arrived in ChatGPT, and the data collection that supports it is now in the policy.

How we rated it

Every change our monitor detects gets a severity rating before it reaches members. We rated this one critical.

The reasoning is simple. Plenty of policy edits enlarge an existing practice, a longer retention window here, a new vendor there. This one creates a practice. Ad history and inferred interests are a new class of personal data for OpenAI to hold, and interest profiles built for advertising describe you in ways a chat log does not. A category that did not exist last month now does.

What it did to the score

OpenAI's consumer privacy rating fell from 5.1 to 4.8 on our ten-point scale. That moves ChatGPT from second to third among the ten model makers we rate, below Google's Gemini at 4.9 and further behind Anthropic's Claude at 5.3.

The entire drop came from one dimension, the one that scores third-party sharing and advertising use. We left the training dimension untouched, and the reason matters: the policy says nothing about whether ads history feeds model training. We score what the text says, and silence is not a disclosure. If OpenAI later states that ad data enters training, that dimension moves too.

The boundaries

Two limits are in the text itself. The new category applies to Free and Go users, so the policy does not extend advertising data collection to paid ChatGPT plans. And it applies to the consumer product, not the API. OpenAI's business terms still prohibit training on customer content by default, and its API scores 8.3 on our rubric. The distance between OpenAI the model provider and ChatGPT the consumer product was already wide. It just widened again.

That gap is the recurring finding of this project. The models are governed by strict contracts. The products wrapped around them are governed by consumer policies that keep getting thinner, and the free tiers are thinnest of all.
