1. Overview
This Privacy Policy describes how EchoFlow Voice ("the app") handles information when you use the application on your Android device.

The app is designed to work entirely on-device with no data collection.
2. Information we do NOT collect
EchoFlow Voice does not collect any of the following:
- Personal information (name, email, phone number, etc.)
- Audio recordings or voice data
- Usage statistics or analytics
- Device identifiers
- Location data
- Crash reports sent to external servers
3. Microphone permission
The app requests access to your device's microphone. This permission is required for the core function of the app — real-time audio monitoring with DAF and FAF effects.
Microphone audio is processed entirely on your device in real time. It is not recorded, stored, uploaded, or transmitted in any form. Once you stop using the app, no audio data remains.
4. Local storage
The app stores your settings (such as delay time, pitch, EQ values, and preferences) locally on your device using Android's DataStore. This data:
- Never leaves your device
- Is not linked to any account or identity
- Can be cleared by uninstalling the app
5. No account required
EchoFlow Voice does not require you to create an account, sign in, or provide any personal information to use any feature of the app.
6. No third-party SDKs or analytics
The app does not include any third-party analytics, advertising, or tracking SDKs. No data is shared with any third party.
The app uses Google Play's in-app review API solely to allow you to rate the app within the Play Store. This is handled entirely by Google and does not involve any data collection by us.
7. Children's privacy
EchoFlow Voice does not knowingly collect any data from users of any age. Since no data is collected at all, the app is safe to use regardless of the user's age.
8. Changes to this policy
If this Privacy Policy changes, the updated version will be published at this URL with a new "Last updated" date. Continued use of the app after any changes constitutes acceptance of the updated policy.
