We collect only what is needed to provide the service and keep the purpose clear.

How we use information

• To support login, account identification, credit spending, download access, and work management.

Uploaded images and works

Uploaded images are used to generate bead patterns, line-art guides, and export files. Works that are not shared publicly are intended for your account features. If you share a work to the gallery, its preview, title, author information, and interactions may be visible to other users.

Retention and deletion

Account, credit, order, and pattern records are kept while needed to provide the service. You can contact us to request deletion, correction, or investigation. Some records may be retained for a reasonable period for transaction, audit, or dispute handling.

Third-party services

The site may use hosting, object storage, payment, analytics, or security providers. We aim to share only the information required for the specific function.
