Privacy policy

Last updated: 10 November 2026. This covers the Hey Interpreter app for Android and Wear OS, and heyinterpreter.com.

In short

• The app listens only while a session is running, which you start and stop.
• Speech audio streams directly to our speech-translation processor to be turned into text and translated. It never passes through Hey Interpreter servers.
• Your conversations are saved only on your phone and deleted automatically after 7 days. We never receive them.
• There is no user account, no ad-network tracking SDK, and no selling of personal data.

What the app uses

• Microphone. During an active session, the phone or watch microphone records speech. A session started on a Wear OS watch relays its audio to your paired phone over Bluetooth.
• Audio and translated text. Your phone streams speech audio directly to Soniox, Inc., our real-time speech recognition and translation provider, and receives translated text back. Soniox processes audio under its terms and privacy policy at soniox.com.
• Saved conversations. Audio and transcripts are kept in the app's private storage on your phone so you can review them in History. They auto-delete after 7 days. You can delete any session immediately in History, or remove all data by uninstalling the app.
• Install identifier & subscription receipt. The app generates a random install identifier on first launch. When starting a session or verifying a Google Play subscription, the app sends this install identifier (and, if subscribed, your Google Play purchase token) to heyinterpreter.com to verify entitlement, restore purchases across reinstalls, and enforce fair-use limits.
• Language settings and country hint. The app reads your device language list and mobile network / time-zone country solely on-device to suggest relevant languages. It never requests GPS or location permission.

What our server sees

Before a session opens, the app requests a short-lived key from heyinterpreter.com so it can connect directly to Soniox. Our server sees the random install identifier, session duration seconds, Google Play subscription state (if purchased), country code, and IP address for rate-limiting. Our server never receives your speech audio or transcripts. Website visits use privacy-friendly first-party analytics without third-party ad cookies.

What we do not do

• We do not sell your data or share audio/transcripts with third parties.
• We do not record in the background when no session is active.
• We do not upload your saved History conversations to any server.

The people you talk to

The app translates whoever speaks near your microphone. Let the people in your conversation know you are using a live interpreter, and follow local laws regarding audio recording where you are.

Children

Hey Interpreter is not directed at children under 13.
