Will My Chat History Be Used for Training?
Could the things you've said to AI become its “textbook”? This page uses a flow diagram to show where the data actually goes, then tells you which kind of settings hide the switch, and what you should never send.
It might — it depends on the product and your settings. Quite a few products use your conversations to improve the model by default, but legitimate products all give you a switch to turn it off. Free tiers lean toward collecting; enterprise plans usually promise they won't touch your data.
You type a sentence in the box and hit send — and it starts a journey. The diagram below simulates that journey. Try flipping that switch and watch how the flow changes. Every node is clickable — tap one for a short note.
Every company's terms look different, but by paid tier, the treatment follows a rough pattern. The table below is common practice in the industry. For any given product, go by its own privacy terms.
| Tier | Used for training by default? | Can you turn it off | Data-retention promise |
|---|---|---|---|
| Free | Mostly on by default — your conversations are more likely to be collected | Usually yes, but you have to go find the switch | Weaker promises; retention periods differ by company |
| Paid | Some on by default, some off by default | Usually yes, and the switch is easier to find | Most write it into the terms, with a clearer retention period |
| Enterprise | Usually a promise not to use it at all | Off by default | Bound by contract — you can hold them accountable if something goes wrong |
Every product names it differently, but the switch hides in similar places. Open settings and look for words like: “Data controls,” “Privacy,” “Improve the model,” “Model training.” You'll find it on both the web version and the mobile app — usually one or two switches. If you really can't find it, type “data” in the settings search box. That'll get you there nine times out of ten.
Numbers and credentials that can get you in trouble immediately
National ID numbers (身份证号), bank-card numbers, passwords and verification codes of every kind. With this kind of information, a single string of digits can cause real damage. Never send it to AI. When you ask a question, just replace it with “so-and-so.”
Company secrets
Internal business data, unreleased product plans, core code. Before you ask AI to polish a document, ask yourself: if this showed up in tomorrow's newspaper, would you panic? If yes, strip the sensitive parts before you send.
Client and other people's information
Contracts, client lists, other people's chat logs. The people involved didn't agree to let AI see this. If you send it on their behalf and something goes wrong, the responsibility is yours.
When you handle work content, use a company-approved enterprise account. Enterprise plans cost more — and what you're paying for is a contract that says, in black and white, “your data stays yours.” Using a personal free account for work secrets is like storing company files in a place whose terms you can't even explain. If something happens, it's hard to account for.
✅ What this page wants to share with you
- Collection is on by default, more often than not: legitimate products all have a switch to turn it off — look in settings for words like “Data controls” or “Privacy”
- Don't put sensitive information in the chat box: ID numbers, company secrets, client data. Deleting the chat won't pull back content already trained into the model
- On a free product, you are also the raw material: one price of “free” is that your conversations are more likely to be used as training material
- Company secrets belong on an enterprise plan: the contract says they won't touch your data. Don't put work content on a personal free account
