Privacy Policy

Echo translates live audio, screen text, and nearby conversations into captions. Depending on your selected language pair, device capabilities, permissions, and network availability, Echo may use on-device Apple technologies or cloud translation services to provide translation.

Echo may process the following information to provide app functionality:

• Audio you choose to translate, including microphone audio for Around Me mode and app audio captured through Apple's iOS Screen Broadcast flow for Audio mode.
• Text recognized from your screen when you use Screen mode.
• Translated captions and source text produced during a translation session.
• Source and target language settings, caption display settings, subscription entitlement state, and app usage state needed to operate Echo.
• Purchase and subscription status provided by Apple through StoreKit.

Echo does not use this information for advertising or cross-app tracking. Echo does not sell your personal information.

When supported by your device and selected language pair, Echo uses Apple on-device speech recognition, text recognition, and translation features. In those cases, the relevant audio or text is processed on your device.

If on-device translation is unavailable for your selected language pair or mode, Echo may send the audio transcript or recognized screen text needed for translation to cloud translation providers, including Microsoft Azure AI Speech and Translator. Cloud processing is used only to provide translation features.

Do not use Echo to translate information you are not allowed to share with a cloud translation service.

Screen mode and Audio mode use Apple's Screen Broadcast flow. Echo uses that flow to access the content you explicitly choose to translate. Echo is not designed to make general-purpose screen recordings, and the app uses captured content only to provide live translation and captions.

Some apps or protected media may block, mute, or restrict capture through Screen Broadcast. Echo does not bypass DRM, app restrictions, or platform protections.

Echo may save translation history locally on your device so you can review, copy, or share previous captions. You can delete history from inside the app.

Echo stores app preferences using Apple-provided local storage. Translation history is stored on your device unless you choose to copy or share it.

Local translation history remains on your device until you delete it in Echo or remove the app. App settings remain until changed, reset, or removed with the app. Cloud translation providers may process submitted content according to their own terms and policies.

Echo Unlimited subscriptions are processed by Apple. We receive subscription entitlement information from StoreKit so the app can unlock paid features. We do not receive your full payment card details.

Echo may rely on Apple services, Microsoft Azure AI services, StoreKit, and other platform services to provide translation, speech recognition, purchases, and app functionality. Those services may process information according to their own terms and privacy policies.

Echo may list or open third-party apps or services such as Weverse or Bilibili. Echo is not affiliated with, endorsed by, or sponsored by those services. Third-party names and logos are used only to identify compatible services.

Cloud translation and platform services may process information in countries or regions outside your own. By using Echo's cloud-backed translation features, you understand that content needed for translation may be processed by those service providers where they operate.

You can:

• Choose whether to grant microphone permission.
• Choose whether to start Apple's Screen Broadcast flow.
• Change source and target language settings.
• Delete saved translation history in the app.
• Manage or cancel Echo Unlimited through your Apple ID subscription settings.
• Contact us with privacy questions at bs-studio-support@proton.me.

Echo is not directed to children under 13. If you believe a child has provided personal information to us, contact us at bs-studio-support@proton.me.

We use reasonable technical measures to protect information processed by Echo. No method of transmission or storage is completely secure.

We may update this Privacy Policy from time to time. If we make material changes, we will update the effective date above.
