432Hz Shift does not collect any personal data. Everything the app does happens on your device. No accounts, no analytics, no tracking, no third-party SDKs.
You pick an audio file from the Files app. The app reads the file, detects its tuning, and writes a new file shifted to A=432Hz back into Files. The original is never modified. Audio never leaves your device.
None. There is no server. There is no account. There is no analytics SDK. The app makes no outbound network requests.
The app uses Apple's standard UserDefaults only to remember your in-app preferences (for example, default output format). This data lives only on your device and is removed when you delete the app.
The app is rated 4+. It collects no data, including from children.
The app requests Files access only to read the audio you pick and to write the converted file back. It does not access the microphone, photos, contacts, location, or any other system feature.
