Privacy at BFL and Stability AI

Black Forest Labs (BFL/FLUX) and Stability AI are image providers, but not subprocessors of AI-Public. They do not receive personal data from AI-Public. This is technically enforced in the backend.

What is sent?​

Only:

  • an English image prompt constructed by the server from a controlled, local catalog;
  • technical image settings, such as model, format, and dimensions.

What is never sent?​

  • the original user prompt or chat history;
  • names, contact details, private addresses, or other personal data;
  • source, inspiration, or reference images;
  • image URLs or base64 image data.

Technical block​

The user request is first converted to only allowed catalog IDs. The server validates these IDs and thus composes the English provider prompt. The BFL- and Stability adapters accept only this validated prompt type and reject ordinary text prompts and all image input.

If a safe catalog prompt cannot be formed, the request is blocked and nothing is sent to BFL or Stability AI.
