Privacy & Data Handling

META Engine does not store your images.

How processing works:

  • Images are resized locally inside Lightroom
  • A compressed preview is sent directly to your selected AI provider
  • The provider returns text metadata
  • Metadata is written into Lightroom fields
  • No permanent storage by ChromaMeta

ChromaMeta does not operate a cloud archive,
and does not collect, resell, or index your photos.

ChromaMeta does not maintain image databases.

There is no content profiling, no dataset reuse, and no resale of user images.

AI usage is billed directly by your selected provider (OpenAI or Google),
under their own data policies.

For maximum privacy, you may review the AI provider’s data handling terms.
