Audio Spectrogram Privacy Policy
CAEN Inc. provides Audio Spectrogram. Questions about this policy can be sent to info@caen.co.jp.
Audio and local storage
The app processes audio files you choose and microphone recordings you start for spectrogram display, analysis, playback, and export. It does not modify the original imported file. Decoded audio, recordings, file names, timestamps, sample rates, timed notes, and preferences are stored in the app's private storage on your device until you delete them.
No developer-server transmission
The app does not send audio or usage data to the developer. It has no ads, analytics, external crash reporting, account system, or internet permission.
Microphone permission
Microphone access is requested when you start recording. File analysis does not need microphone permission. Recording status is displayed while recording. Recording stops and is saved when you stop it, leave the app's foreground, or lock the screen. Background recording is not supported.
Export and sharing
The app passes only the output you choose to the storage provider or sharing app you select. Cloud destinations and other apps handle that output under their own terms and privacy policies.
Deletion, temporary files, and backups
Audio and timed notes can be deleted from Library. Clearing app storage or uninstalling removes internal app data. Exported files remain at their destinations until you delete them there. Import temporary files are deleted when processing finishes; files left after an abnormal exit are cleaned on the next launch. Sharing caches older than 24 hours are deleted at the next export. App data is excluded from automatic cloud backup and device transfer; the app does not provide cloud synchronization.
Payment
Audio Spectrogram is a paid download without subscriptions or additional purchases. Google Play processes purchases and payments. The app does not receive or store payment card information.
