As with any application, you should always take a close look at the Terms of Use and Privacy Policy of the AI tool you are using, so you have an understanding about the service, what you are allowed to do, and what happens with any data you provide. For example, OpenAI's (ChatGPT) Terms of Use and Privacy Policy, state:
- OpenAI collects personal information you provide. This includes your name, contact info, payment info, files you upload, messages you send, and activities on related social media accounts
- OpenAI collects personal information automatically when you use the service. This includes log data (your IP address, date, etc.), usage data (what you did), device information (what you used), and cookies (websites you visited)
- OpenAI states that they "may provide your Personal Information to third parties without further notice to you". These third parties include vendors, other providers, law enforcement, and affiliates.
This means that your personal information is not private and may be shared for commercial or legal purposes. This likely applies to other AI tools in a very similar way.
