Short answer: on a consumer plan, usually yes unless you turn it off — and even with it off, your conversations are still stored and still attached to your account. Those are two different problems, and most advice only addresses the first one.
Training is a setting, and the default depends on your plan
Every major provider now has a data control that governs whether your conversations can be used to improve their models. The setting is real and it works. What varies is which way it points before you touch it: consumer plans have generally defaulted to allowing it, while business, enterprise, and API access generally default to not.
So the honest version of the answer is: it depends on which door you came in through, and you should check rather than assume. These policies change often enough that anything written down — including this page — is a starting point, not a citation.
Turning training off does not mean the conversation is gone
This is the part that catches people. Opting out of training and deleting your data are separate controls that do separate things:
- •Training opt-out stops future conversations feeding model improvement.
- •Retention is how long the conversation sits on their servers regardless. Most providers keep chats for a defined window for abuse monitoring and support, even with training off.
- •Deletion is a third thing you have to do yourself, and it is usually a process rather than an instant erase.
You can have training switched off and still have a searchable archive of everything you ever asked, sitting under your real name and email.
The account is the actual problem
Almost all of this advice treats the conversation as the sensitive thing. It usually isn't on its own. What makes a chat log sensitive is that it's attached to you — an email address, a phone number, a payment method, an IP.
A question about a medical symptom, a severance package, or a difficult family situation is unremarkable as one row among billions. It becomes something else entirely when it's row 47 under your name, next to the other forty-six.
Which is why "did you turn off training?" is a smaller question than it looks. The identity link is the thing doing the damage, and no data-controls toggle addresses it.
What actually reduces the exposure
In rough order of how much work each one does:
- •Break the identity link. If the provider never learns whose question it is, the archive stops being a profile and goes back to being one row among billions.
- •Turn off training anyway. Free, takes a minute, worth doing in every tool you use.
- •Keep identifiers out of the prompt. Whatever you type travels regardless of any setting. Generalize the situation instead of pasting the specifics.
- •Delete what you don't need. A shorter history is a smaller target if there's ever a breach.
How Secure AI handles it, including the caveats
Secure AI is built around the first item on that list. Your app talks to a server we run, and that server talks to the AI providers using its own credentials. No account id, email, or name is attached to the request. The provider sees the words and has no idea who sent them.
Two things that are true and worth saying plainly, because most privacy pages leave them out:
- •We don't scrub the text of your message. If you type your own name into a prompt, your name reaches the provider. Breaking the account link is structural; reading your mind is not.
- •We keep a 90-day log of exchanges, keyed by a one-way hash of your account id. That makes it pseudonymous, not anonymous — it can't be read backwards into a person, but exchanges from the same person group together. We'd rather tell you that than let you find it.
Our full privacy policy spells out both. If you want the longer version of how the architecture works, the what is Secure AI explainer covers it.
