Privacy Notice

H3 Studio verifies your identity with an email code. Resend delivers the code; the code proof and session hash are stored in this project's separate database. The sign-in cookie is HttpOnly and Secure, so browser scripts cannot read it.

Creative data

Prompts, generation settings, job status, and image records are stored on the server. Reference images and results are encrypted with a project-specific key before upload to Cloudflare R2. Decrypted images are available only after account ownership checks. Prompts are stored as database text; we do not claim they are end-to-end encrypted.

The model runs on the operator's Mac. The Mac fetches jobs through an outbound encrypted connection. Temporary reference files and results are cleared after each job. There is no public local device port or general network tunnel.

Retention and deletion

Generated images are stored in Cloudflare R2 for only 24 hours after completion, then deleted automatically. After cloud expiry, the cloud copy can no longer be viewed or downloaded. While signed in with this page open, this browser attempts to save each generated image automatically in IndexedDB. You can view and download that browser copy after cloud expiry on this device. Browser storage is not a separately downloaded file; it can be lost when browser data is cleared, in private browsing, or when storage is low, and it does not sync to other devices. Download important images promptly. Job records and settings may remain so you can generate again. You can delete an image earlier; doing so removes its generated file, job record, and this browser's local copy. Reference images retained for reusing settings are stored separately and are not subject to the 24-hour generated-image limit. To delete all account data and references, contact the operator. Verification codes expire after five minutes; sessions expire after seven days, and signing out revokes the current session immediately.

Scope

This is a personal trial limited to approved email addresses. Do not upload photos or other sensitive material that you are not authorized to process. Creative data is not used to train other models.
