1. Scope and contact
This policy describes the current SELUNE iPhone app and this website, operated by Cheng Xing. It was updated on November 15, 2026. For privacy questions, contact support@xingcheng.me.
2. Your photographs stay under your control
The app performs film image processing on your device. Photos, Live Photo video and sound, film and lens settings, roll records, notes and selected shooting locations are stored in your Photos library or the app’s local storage as needed. SELUNE does not operate a photo-upload or photo-processing backend, and does not automatically send your library to us.
3. Permissions are used for specific features
Camera access enables capture; Microphone access records sound for Live Photos; Photos access lets you select, read, process and save images. Optional Location access helps you choose a shooting location on a map. You can deny or revoke permissions in iOS Settings, although the associated feature may then be unavailable. Map search and geocoding use Apple services, which may receive the search or location information required to provide the result.
4. Optional cloud connections
If you choose Google Drive, Baidu Netdisk or WebDAV import, the app communicates directly with that provider or the server you specify to authenticate, list files and download selected images. Authentication details and requests are handled by that service under its own policies. OAuth credentials are stored using the iOS Keychain. Other connection settings are stored on your device. We do not receive your cloud password or imported files on a SELUNE server. You can disconnect supported linked accounts and revoke authorizations with the provider.
5. Advertising and analytics
The current app does not include advertising, cross-app tracking or third-party analytics SDKs. It does not ask you to create a SELUNE account. Apple may provide developers with aggregate App Store statistics or diagnostics according to your Apple settings and Apple’s policies.
6. Retention, removal and system services
Local records remain until you remove them or remove the app, subject to system backups. Removing a gallery item does not remove its system Photos original. System Photos, iCloud Photos, device backups, Keychain credentials and cloud-provider copies are managed separately by iOS, your Apple account or the relevant provider. Keep copies of important photographs and use those services’ own controls to manage their data. Information you voluntarily email to support is used to answer your request and investigate the reported issue; do not include unnecessary sensitive information.
7. This website
This static website does not set analytics or advertising cookies and has no tracking scripts, account system or submission form. Hosting, delivery and security providers, including Cloudflare, necessarily process connection information such as IP address, request URL, time and browser information to deliver and protect the website. Email links open your chosen email app; sending a message discloses the information you include to our support mailbox and the involved mail providers.
8. Your choices and changes
You can manage system permissions, remove local app data, revoke cloud authorizations and contact us about information you voluntarily provided to support. Where applicable, you may request access, correction or deletion of that support information, subject to legal requirements. The app does not target children or knowingly request their personal information. We will update this page when the app’s data practices materially change.
