Yes. If “opting out of training” means turning off the documented model-improvement control, that setting does not delete or hide saved chats. Regular chats can remain in chat history until deletion or an applicable workspace retention rule removes them.
Training opt-out and chat deletion are separate
The relevant Help Center statement draws a clear distinction: turning off model improvement controls one setting, while removing a saved chat requires a separate action. An opt-out therefore should not be treated as proof that previous conversations have been erased.
The documentation also says that regular chats follow the account’s personalization and data settings. Their continued presence cannot be assessed from the model-improvement setting alone.
This answer concerns saved chats in history. The cited statements do not establish that every separate category of operational, security or other server-side log is removed—or retained—under the same rule.
How to check the current status
- Confirm the model-improvement setting. Review the relevant data-control page and verify that the documented model-improvement option is actually off.
- Review chat history. Check whether regular conversations remain listed, particularly any chats that should no longer be retained.
- Use deletion separately. For a saved chat that should be removed, use the applicable deletion control rather than assuming the model-improvement opt-out handled it.
- Check account data settings. Regular chats follow personalization and data settings, so those settings need to be reviewed independently.
- Identify any workspace retention rule. Where a workspace applies, determine whether its retention policy affects when regular chats are removed.
- Verify the result. After taking a retention-related action, revisit chat history to confirm whether the conversation is still present. The cited statements do not provide a deletion deadline.
What the reader must still confirm
The cited statements do not specify a universal retention period, a guaranteed deletion time, or identical handling for every type of chat. They also do not turn the model-improvement opt-out into a general data-erasure request.
For an individual account, the decisive evidence remains the current control status, the chat’s placement in history, the applicable account settings, and any governing workspace retention rule.
