There is no general answer: providers and plans differ, and their terms change. Rather than a verdict, here is what to examine. This is not legal advice.
What to find out
- Use for training. Does the provider use your inputs to train its models, and can you opt out?
- Retention. How long are requests stored, and can that be limited?
- Location. Where is data processed? This matters under data protection rules in the EU.
- Sub-processors and agreements. Is there a data processing agreement that fits your obligations?
- Access and security. Who can see the data and what certifications or controls exist?
What you can do on your side
- Minimise. Send only what the task needs. Remove names and identifiers where they are not needed.
- Classify. Decide which data must never leave your systems.
- Separate keys and environments, and keep secrets on the server.
- Tell people. Your privacy information should say if personal data is processed by an AI provider.
- Consider alternatives such as a provider region you can choose, or a model you run yourself, for data that is too sensitive.
Also beware of inputs
Text from outside, such as emails or web pages, can contain instructions meant to manipulate the model. Do not give an AI feature more access than it needs.
Check the current terms yourself; I cannot vouch for any provider’s policy here.
