Your signals stay yours.

Data collection

MorseScope does not transmit personal data, audio, encoded messages, decoded text, usage analytics, identifiers, or diagnostics to the developer or to third parties.

Microphone access

Microphone access is optional and is requested only when you start live Morse decoding. Received audio is processed locally and retained only in a bounded in-memory buffer containing approximately the latest ten seconds. The buffer is continuously replaced and is discarded when listening stops.

The App Store version does not save or export live microphone audio.

Premium Decoder Pro can display a bounded ten-second live energy waterfall. Stopping may freeze that recent visual in memory until you tap Clear or begin another listening session. The waterfall is not saved in the Session Library, included in exported diagnostics, uploaded, or shared.

Imported and exported files

WAV, MP3, M4A, and AAC files you import are processed locally. Morse code and WAV or M4A files you export are written only to the location you choose. MorseScope does not upload or otherwise access those files after export.

Preferences and practice data

The app stores Encoder settings and local Practice data—including course progress, accuracy and response evidence, recent results, custom presets, and WPM-ladder progress—using Apple’s app-private storage. These preferences and practice records are not transmitted off-device.

Flashlight and haptics

Optional Encoder output can pulse the device’s rear flashlight or haptic hardware. Flashlight output only changes the torch state: MorseScope does not capture or retain camera frames, photos, or video, and transmits nothing from the camera. Haptic and flashlight output are generated locally and stop when you stop output, leave Encoder, or background the app.

Purchases

Optional MorseScope Premium purchases are processed by Apple through the App Store and StoreKit. The app reads Apple-signed product and entitlement information to display localized purchase options, unlock Premium, restore purchases, and reflect subscription status. The developer does not receive your payment-card details. Apple processes purchase information under Apple’s own privacy policy.

Network access and tracking

MorseScope's core encoding, decoding, and practice features work offline and do not use a developer-operated network service. A network connection may be required to load App Store product information, purchase or restore Premium, or manage a subscription. MorseScope does not track users across apps or websites.

Children’s privacy

Because MorseScope does not collect or transmit user data, it does not knowingly collect personal information from children.

Changes

If the app’s data practices change, this policy and the App Store privacy disclosure will be updated before the changed version is released.
