We were playing with a new image tool recently. It was genuinely fun, and within about ten minutes we wanted to upload personal reference photos to see what it would do with them. That was the moment worth stopping at, because AI training on your data is the default almost everywhere, and the photos would have gone into the pile.

So we paid for the ten dollar tier, went into the settings, turned training off, and carried on playing. Total cost, ten dollars and four minutes.

What AI training on your data actually means

Training is how a model builds its knowledge. What goes in can come back out.

Put your data in the training set and it becomes part of what the model knows, which means it can inform an answer given to someone else. Not usually word for word, and not usually in a way anyone could trace back to you. But the reality is that you have handed over a copy and given up any say in where it surfaces.

For a family photo that is a discomfort. For a client list, a contract, an unreleased product plan, or a customer’s personal information, it is a different category of problem.

Does paying stop AI training on your data?

No. This is the part most people have backwards, and it has changed recently.

On the major consumer tools, a paid personal plan allows AI training on your data by default in the same way the free tier does. The subscription buys you capability, not privacy. What actually stops it is a setting, and the setting is off by default in the sense that matters: training is on until you turn it off.

The exception worth knowing is the business and enterprise tiers, which generally do not train on customer content as a term of the contract rather than as a checkbox. That is a genuinely different product, and it is why “just get the paid version” is incomplete advice.

Where the setting lives

The switch that governs AI training on your data is rarely labeled privacy. Look for language about improving the product instead.

It is usually labeled something like “Allow us to use your data to improve our products” or “Help us improve our AI models,” and it tends to sit in one of a few places:

Settings, then a section called Data Controls or similar
Your account or profile menu, under Privacy
An activity or history setting, where turning off history also turns off training
A separate toggle for uploads and files, which is not always the same switch as the one for chats
The workspace or admin console, if someone else administers your account

Vendors move these. The specifics in any guide, including this one, go stale, so treat the labels as what to search for rather than as directions. Every vendor also publishes a privacy policy, Anthropic’s is here as one example, and it is the authority when a blog post and a settings screen disagree.

What we do before putting anything into a new tool

Four minutes, in this order, every time.

Find the training setting and turn it off, before the first upload rather than after
Check whether the setting covers uploads and files, not just typed conversations
Decide what class of thing we are willing to put in this tool, and hold that line while the novelty is strong
On anything client-related, use the business tier or do not use the tool

That last one is not caution for its own sake. When a client’s information is involved, the question is not what we are comfortable with. It is what we told them we would do.

The new apps are the harder case

An app is only as private as the platform underneath it, and you usually cannot see the platform.

There is a wave of genuinely useful new software built by experts in their own fields who are not software companies. The tool they built it on has its own training defaults, and those defaults now apply to the data their customers type in. Most people using the app will never know which platform it was, let alone what its settings were set to.

Ask, before you trust it with anything that matters. How it was built, what it was built on, and whether that platform trains on what goes in. A creator who cannot answer has not asked either.

Frequently Asked Questions

Does turning off AI training on your data delete what I already shared?

No, and this is the reason to check settings early rather than eventually.

Opting out stops future training and usually shortens how long the vendor retains your data. It is not erasure, and anything already used in a completed training run cannot be pulled back out.

Is it safe to use free AI tools at all?

Yes, for the right things.

Free tools are fine for work you would be relaxed about publishing: drafting, brainstorming, code you would open source anyway, questions with nothing identifying in them. The rule is about the data, not the price.

What should never go into a consumer AI tool?

Anything that belongs to someone else.

Client data, customer personal information, contracts, credentials, unreleased plans, anything covered by an agreement you signed. If you would not put it in a public forum, a consumer AI tool is closer to that than most people assume.

How often should we check these settings?

Whenever a tool prompts you about a new feature, and once a quarter otherwise.

Settings get added and occasionally reset. New features often arrive with their own separate toggle, defaulted on, which is how people who opted out a year ago end up opted back in for uploads.

Ten dollars and four minutes

The image tool was worth the ten dollars, and we are still using it.

That is the point rather than an aside. Stopping AI training on your data is not about avoiding AI tools, it is about spending a few minutes before the fun starts instead of thinking about it afterwards. We built our own software for our back office partly for this reason: some data should not leave the building at all.

If you are working out where that line sits for your business, that is a conversation we have most weeks, and it is part of what our engagements cover.
