Privacy Policy — Echo: Voice Diary

Last updated: 12 May 2026  ·  Developer: Klaus Siebeneicher, Vienna, Austria

This privacy policy explains how the "Echo: Voice Diary" app ("the App") handles your data. Echo: Voice Diary is a personal voice diary app for iOS. We take data protection seriously and have designed the App to process as little data as possible.

1. Who is responsible (Controller)

The person responsible for data processing within the meaning of the GDPR / DSGVO is:

2. What data the App processes

The app stores all data exclusively on your device. There is no account system, no backend server, and no cloud sync. We do not have access to your recordings or any other personal data you enter.

2.1 Voice recordings

The App records audio via your device's microphone when you choose to create a diary entry. Recordings are saved locally in the App's private storage on your device. They are not transmitted to us or any third party.

2.2 App settings and preferences

Settings such as your display name, theme preferences, and onboarding status are stored locally using the device's AsyncStorage. This data never leaves your device.

2.3 Microphone permission

The App requests access to your device's microphone solely for the purpose of recording diary entries. Without this permission the core function of the App is not available. You can revoke this permission at any time in your iOS system settings.

3. Data we do not collect

The app does not collect, transmit, or store any of the following:

4. Data processed by third parties (Apple & Google)

The App is distributed through the Apple App Store and Google Play Store. Apple and Google may independently collect certain technical and diagnostic data as part of operating their respective platforms — for example, crash logs and aggregate usage statistics. This data is processed under their own privacy policies. We do not receive or control this data.

5. Legal basis for processing (GDPR Art. 6)

All data processed locally on your device is processed exclusively to provide the functionality of the App you have installed. The legal basis is Art. 6(1)(b) GDPR (performance of a contract / provision of the requested service) and Art. 6(1)(f) GDPR (legitimate interest in operating a functional app) where applicable.

Because no personal data is transmitted to us, no further legal basis is required on our part for remote processing.

6. Data retention and deletion

All data (recordings, settings) is stored on your device for as long as the App is installed. You can delete individual recordings within the App at any time. Uninstalling the App removes all locally stored data from your device.

7. Your rights under the GDPR / DSGVO

As a data subject within the EU, you have the following rights under the GDPR:

To exercise any of these rights, or if you have questions about data protection, please contact us at ks.siebeneicher@gmail.com.

You also have the right to lodge a complaint with the Austrian data protection authority (Datenschutzbehörde, dsb.gv.at) if you believe your rights have been violated.

8. Changes to this policy

We may update this privacy policy from time to time to reflect changes in the App or legal requirements. The current version is always accessible via the link provided in the App Store listing. We recommend reviewing this policy periodically.
