How to Answer: Is Customer Data Used to Train Your AI Models?

The safest answer to 'Is customer data used to train your AI models?' is specific, bounded, and evidence-backed. Do not answer with vague responsible-AI language. Say exactly what data is used, what is not used, which providers are involved, and what controls apply.

Why buyers ask this question

Enterprise buyers ask because they need to understand whether their confidential data, personal data, regulated data, or proprietary business information could become part of a model training process they do not control.

• They want to know if their data leaves your environment.
• They want to know if a model provider can use it for training.
• They want to know if prompts and outputs are logged.
• They want to know if retention and deletion obligations can be honored.
• They want to know if data can leak into another customer's output.

A strong answer structure

1. 1.State whether customer data is used for training.
2. 2.Define what counts as customer data in your answer.
3. 3.Identify any model providers or subprocessors involved.
4. 4.Explain whether prompts, outputs, embeddings, or logs are retained.
5. 5.Describe opt-out, deletion, or zero-retention options if available.
6. 6.Link to the supporting DPA, subprocessor list, privacy policy, and technical controls.

Example answer pattern

Example: Customer content submitted through the product is not used to train our proprietary or third-party foundation models. We use approved model providers to process prompts and outputs for product functionality. These providers are listed in our subprocessor register. Prompt and output retention follows our data retention policy and customer agreement. Customer data is logically isolated between tenants and is not used to generate outputs for other customers.

Evidence to attach

• Data processing agreement.
• Subprocessor list.
• Privacy policy.
• Data flow diagram.
• Model provider terms or data controls summary.
• Retention and deletion policy.
• Tenant isolation and access control summary.
