Vendor data-handling terms

Training on your data (default tier)
Inputs used to train and improve models; opt-out right stated

The privacy policy lists training and improving models among the purposes for processing prompts and uploaded content, and grants a right to opt out of that use. No account-level default toggle is described.

“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.”

Data residency
May be stored outside the user's country; location not specified

The current policy does not name a storage country. Earlier versions of the policy stated storage in the People's Republic of China; the wording checked on the date below does not.

“The Personal Data we collect from you may be stored on a server located outside of the country where you live.”

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.
