Who can see my chats on a shared GPT3.5 account?

On a shared account, your conversations are saved to the account and visible to every other user in the left-hand chat list. Never enter identity, financial, or other sensitive details.

How history sharing works

ChatGPT history follows the account, not the device. A chat you start on your laptop shows up for anyone who signs in on their phone with the same account — and vice versa.

Three ways to protect yourself

1. Use Temporary Chat

1. Open ChatGPT and click the model name at the top.
2. Toggle on Temporary chat in the menu.
3. Conversations in this mode are never saved to history — close the page and they're gone.

2. Delete after use

1. Find your conversation in the left-hand list.
2. Click the … next to it → Delete → confirm.
3. Once deleted, other users can no longer see it.

3. Keep sensitive content out entirely

Never paste into a shared account: real names with ID numbers, bank or credit card details, passwords of any kind, or confidential work documents. For that kind of work, a product tied to your own account (such as Plus Top-Up) is the right choice.

Be considerate of other users too

• Don't delete conversations that aren't yours;
• Don't use Delete all chats or Log out of all devices in settings;
• Don't change account-wide personalization (Custom Instructions, etc.) — it affects everyone.
