The launch product is intentionally simple: private generation, local storage, and a clear Pro upgrade. Here are the basics.

The launch product is intentionally simple: private generation, local storage, and a clear Pro upgrade. Here are the basics.

Does PhoneDiffusion need an account?

No. PhoneDiffusion launches as an accountless iPhone app with no hidden profile and no cloud sync.

Are my prompts or images uploaded?

No. Prompts, negative prompts, generated images, render history, metadata, and downloaded model files stay on device unless you explicitly choose to share diagnostics or export an image.

Which models are supported at launch?

The launch lineup routes devices across Stable Diffusion 1.5, Stable Diffusion 2.1 Base, and Stable Diffusion XL Base 1.0 depending on hardware capability.

What does PhoneDiffusion Pro unlock?

PhoneDiffusion Pro unlocks premium curated launch models plus manual CFG control, manual diffusion step control, and batch generation controls.

What is included in diagnostics?

Support diagnostics may include app version and build, device capability tier, selected model, runtime and thermal state, and local counts such as installed models and saved renders. They exclude prompt text, generated images, and payment details.

Do I need to grant Photos access?

Only if you explicitly save an image. PhoneDiffusion requests add-only Photos permission at save time, not at launch.
