“To improve and develop the Services and to train and improve our technology, such as our machine learning models and algorithms. / the right to opt-out of using your Personal Data for training our models or optimizing our technologies.”

Assessment

Consumer app and web: highAPI: high

Reasoning: Prompts and uploads are processed for model training with only an opt-out right, no fixed retention period is stated, and the storage location is not disclosed beyond "outside of the country where you live". For an EU deployer that is a third-country transfer of whatever is in the prompt, with no processor agreement offered on the consumer service. The API terms checked do not add a no-training commitment.

Flags: GDPR Chapter V (undisclosed third-country storage) · GDPR Art. 28 (no processor agreement on consumer tiers) · Assessed 2026-09-15. The assessment is Unseen's; the terms above are the vendor's.
