Privacy policy

Last updated: 11 November 2026. This policy covers Hey Interpreter on iOS, watchOS, Android, Wear OS, and heyinterpreter.com.

Summary

• The app listens only during an active session that you start and stop.
• Speech audio streams directly from your phone to Soniox for transcription and translation. Audio does not pass through Hey Interpreter servers.
• Saved conversations stay on your phone and delete automatically after 7 days. We do not receive them.
• You do not create an account. We do not include third-party ad SDKs or sell personal data.

What the app uses

• Microphone. During an active session, your phone or watch microphone records speech. A session started on an Apple Watch or Wear OS watch sends compressed audio to your paired phone over Bluetooth or Wi-Fi.
• Audio and translated text. Your phone streams speech audio directly to Soniox, Inc., our speech recognition and translation processor, and receives translated text back. Requests use real-time zero-retention processing so Soniox discards audio and transcripts after delivering the stream rather than storing or training on them; see soniox.com/privacy.
• Saved conversations. Audio and transcripts stay in private app storage on your phone so you can review them in History. The app deletes them after 7 days. Delete any session immediately in History, or uninstall the app to remove all local data.
• Install identifier and subscription receipts. On first launch, the app creates a random install identifier. When you start a session or verify an App Store or Google Play subscription, the app sends this identifier and your signed transaction or purchase token to heyinterpreter.com to check entitlement, restore purchases after reinstalls, and track fair-use limits.
• Language and country hints. The app reads your device language list and mobile network or time-zone country on-device to suggest nearby languages. It never requests GPS or location permission.

What our server sees

Before a session starts, the app requests a short-lived Soniox key from heyinterpreter.com. Our server records the random install identifier, session duration in seconds, App Store or Google Play subscription status, country code, and IP address for rate limiting. Our server never receives your speech audio or transcripts. Website visits use first-party analytics without ad cookies.

What we do not do

• We do not sell personal data or share audio or transcripts with advertisers.
• We do not record when no session is running.
• We do not upload your History conversations to our servers.

Other people in the conversation

The microphone picks up speech around you. Tell the people you speak with that you are using a live interpreter, and follow local audio-recording laws.

Children

Hey Interpreter is not directed at children under 13.
