Processing on iPhone
Pose analysis, face analysis, horizon and subject detection, shot ranking, composition suggestions and color filters run on device using Apple frameworks. The app has no server-upload pipeline for those functions.
Only the necessary permissions
Camera access is used for capture. Add-only photo permission is used for saving. The iOS picker lets you select reference images without granting full-library access. You can revoke permissions in iOS Settings at any time.
Storage and deletion
Personal templates and resized reference images are stored in the app's private data area. Delete a template to remove its reference copy; uninstall the app to remove local app data. Photos saved to Photos are managed separately, including your iCloud Photos settings.
Payments through Apple
StoreKit and RevenueCat handle Pro entitlements. Payment details are managed by Apple and are not entered into Cham Photo or this website.
Website security
The website needs no account, requests no camera access, has no forms and sends no image data. Deployment headers restrict external content and prevent other sites from framing the page. The support button opens your email app.
Report an issue
When you contact support, describe your iOS version, device and reproduction steps. For personal-data issues, describe the behavior first without sending sensitive data or photos.
