Information We Collect

Photos and Videos

• Photos You Take or Upload: When you take a photo using the App's camera or upload a photo from your device, we temporarily process the image to generate animated videos.

How We Use Your Information

Photo Processing

• Photos you take or upload are sent to our third-party video generation service (Kie.ai) to create animated videos. This processing is necessary to provide the App's core functionality.
• Photos are transmitted securely and are not stored by the third-party service after processing is complete.

Local Storage

• Generated videos are stored locally on your device in the App's documents directory.
• Video metadata (URLs, creation dates) may be stored locally using iOS UserDefaults for the App's collection feature.
