Desktop application

Your ideas, scripts, images, narration, subtitles, videos and reports are written to your local disk. The application does not send telemetry.

Your API keys are encrypted with Windows DPAPI and stored on your computer. They are sent only to the provider endpoints you select.

Hosted demo and license portal

The hosted demo stores the email address, activation code state, job status, generated media and a hashed client IP needed to operate and protect the service.

The license portal stores the order email, tier, network, amount, public transaction hash and license status. It never asks for a wallet seed phrase or private key.

Cookies and analytics

The website uses privacy-friendly Vercel Analytics to count page views. The license portal uses no advertising cookies.

The desktop application does not use cookies for tracking.

Retention and rights

Demo media is removed on the retention schedule. License and order records are kept while needed for support, accounting and legal obligations.

You can request access, correction or deletion of your data by emailing contact@butterflyengine.app. We may need to keep transaction records where the law requires it.

Providers

When you use the application, the AI providers you configure receive the data needed to answer your request. Their privacy policies apply to that processing.
