Extension Changer processes selected files locally on your device. We do not collect, store, upload, sell, or share personal data or file contents.
The app uses Apple system pickers for Photos and Files. It can access only the items you explicitly choose. Converted files stay on your device unless you decide to save, send, or share them.
Extension Changer does not use accounts, advertising, analytics, tracking, third-party SDKs, or server-side file processing.
