Controller

The controller of EchoFlow Voice and the data processed in connection with the app is Janusz Wierzchowski.

What the app is

EchoFlow Voice is an audio app for hearing your own voice with DAF and FAF effects, adjusting audio settings, and viewing microphone signal activity.

The app is not intended for diagnosis, treatment, health monitoring, or medical services.

What data may be used

• microphone input, if the user grants the RECORD_AUDIO permission
• local app settings, including audio settings, language settings, and interface preferences
• technical information required for the app to operate on a given device

How data is used

• to run DAF, FAF, and microphone visualizer features
• to save local app settings
• to save audio-path settings and latency compensation
• to ensure proper operation of the app on the device

Whether data is sent off the device

In the current version, the app does not send user data to external servers. The app does not include account login, cloud sync, or its own remote upload panel for recordings.

Data storage

Settings are stored locally on the user's device. Microphone input is used to run app features and is not automatically published or sent to external services by the app itself.

Permissions

• microphone (RECORD_AUDIO) for DAF, FAF, and visualizer features

Without microphone permission, audio features may be limited or unavailable.

Ads, analytics, and data sharing

• the app does not show ads
• the app does not require account login
• the app does not sell data
• the app does not share data with data brokers

Data deletion

Because data is stored locally, the user can delete it by clearing app data in Android settings or by uninstalling the app.

Changes to this policy

This privacy policy may be updated if app features or legal requirements change. The latest public version will be published with an updated date.
