The safest way to use ChatGPT with private code is to combine product settings, plan choice, and good operational habits. Do not rely on one toggle alone.
The most important distinction
OpenAI’s official privacy docs distinguish between individual services and business offerings. For individual ChatGPT use, content may be used to improve models unless you opt out or use Temporary Chat. For ChatGPT Business, Enterprise, Edu, and the API, OpenAI says data is not used to train models by default.
The safest practical approach
- avoid sharing secrets you do not need to share
- redact credentials, keys, and client identifiers
- use Temporary Chat for sensitive one-off work
- turn off model training in Data Controls if appropriate
- use Business or Enterprise-grade offerings for client work when needed
Why Temporary Chat matters
OpenAI’s help articles say Temporary Chats do not appear in history, do not use or create memories, and are not used to improve models. That makes them a strong default for more sensitive ad hoc work.
What Business and Enterprise change
OpenAI’s business privacy page says organization data is not used to train models by default for ChatGPT Business, Enterprise, Edu, and the API platform. That is a much better fit for client or company work than a casual consumer workflow.
What still matters even then
- least-necessary sharing
- good internal policy
- manual review of outputs
- awareness of third-party apps and actions

Quick FAQ
Is Temporary Chat enough for every private workflow?
It helps a lot, but you should still minimize what you share.
Are business offerings different?
Yes. OpenAI says business and enterprise offerings do not train on your organization’s data by default.
