Your paper. Your privacy.
No account, ads or analytics SDKs. How the app, sharing and support email handle information.
Scope and contact
Updated: October 11, 2026. This policy applies to the FoldMuse app provided by LIPEI ZHANG and this support website. For privacy questions, contact zzsoftservice@outlook.com.
No data collected by the app
FoldMuse requires no account and includes no advertising, tracking or analytics SDKs. The app does not send artwork, images, device identifiers or usage history to the developer, or sell that data.
Processing on your device
The workspace, history, settings and saved artworks are stored in the app's local directory. You choose individual images through the system photo or file picker. The app does not request access to your entire photo library. Imported images are resized locally, stripped of metadata and embedded in artwork files. On compatible devices, hinge readings are used only for local folding interaction and are not sent to the developer.
Export, sharing and backups
Exporting or sharing is initiated by you. A PNG image or .origami file is passed to the destination you select. System backups, iCloud file locations and third-party sharing services follow their own policies and your settings. The developer does not hold those copies.
Manage and delete your data
You can remove paper images and saved artworks in the app. Removed artwork files remain in Files → FoldMuse → Recently Deleted for recovery; delete them permanently using Files. Removing the app removes its local data. Exported and backed-up copies must be managed separately at their destinations.
Support email
If you choose to email us, we receive your email address, message and any attachments you send, to respond and investigate the issue. Email providers also process correspondence. Avoid sending unnecessary private content. We retain support correspondence only as needed to handle the request and applicable obligations. Contact the support address to request access, correction or deletion of information you sent us.
