Midjourney
Midjourney's privacy policy covers personal data collected through its services and through the process of training Midjourney machine-learning algorithms, but the reviewed text does not expressly state that every user prompt or upload is used to train models.
The policy identifies training-related data collection and says personal data may be used to provide, maintain, and improve the service, without a direct prompt-to-training mapping in the reviewed pages.
No model-training opt-out is stated. Users can request account and personal-data deletion; cookie and advertising controls are separate from model training.
Prompts, uploaded images, and other submitted content are collected. This consumer creative service should not be treated as a private enterprise inference endpoint.
Personal data is retained as necessary for stated purposes and legal obligations; usage data is generally retained for a shorter period.
The reviewed privacy materials do not provide one general human-review statement.
