Privacy Policy

Private Diffusion generates images entirely on your device. Your prompt and the generation process never leave it. The app makes no app-code network calls after the model download, has no analytics SDK, and stores nothing on a Numen server. Optional gallery sync, when you turn it on, uses your own private iCloud, not a Numen server.

The TestFlight beta signup on this site is a separate system from the app. It stores your email address only to send your invite and manage your beta access, and we never share it. A full privacy policy will be published before launch.
