Privacy Policy — Real-Time Translator Extension

Last updated: 2026-04-14

1. Introduction

Real-Time Translator ("the Extension") is a browser extension that provides live speech-to-text transcription, translation, and optional text-to-speech playback of browser tab audio and microphone input. This privacy policy explains what data the Extension accesses, how it is handled, where it is stored, and whether it is shared.

2. Data Collection

The Extension does not collect, transmit, or share any personal data with the Extension developer or any third party controlled by the developer. Specifically:

• No personally identifiable information is collected.
• No browsing history, URLs, or page content is collected.
• No analytics, telemetry, tracking pixels, or usage metrics are collected.
• No cookies are set by the Extension.

3. Data Handling

The Extension handles the following categories of data during normal operation:

• Audio data: When you activate speech capture, audio from your browser tab or microphone is streamed in real-time to the speech recognition service you have configured (e.g., Soniox, or your own self-hosted server). Audio is processed in-memory as a transient stream and is never recorded, stored, or cached by the Extension — either locally or remotely.
• Transcription and translation text: Text returned by the speech recognition and translation services is displayed in the Extension's panel. This text exists only in the browser's runtime memory and is discarded when the tab is closed or the panel is cleared.
• User preferences: Settings you configure (language pair, ASR provider, display preferences, TTS voice) are saved locally on your device using Chrome's chrome.storage.local API.
• API keys: If you enter API keys for third-party services (Soniox, ElevenLabs, DeepL, Google Cloud), these keys are stored locally on your device using Chrome's chrome.storage.local API. They are used solely to authenticate requests to the services you have configured.

4. Data Storage

All persistent data is stored locally on your device using Chrome's built-in chrome.storage.local API. Stored data includes:

• Selected speech recognition provider and server URL
• Source and target language preferences
• Display settings (font size, panel position, show/hide original text)
• TTS provider and voice preferences
• API keys for user-configured services

No data is stored on any server controlled by the Extension developer. You can delete all stored data at any time by uninstalling the Extension or clearing extension storage in your browser settings.

5. Data Sharing

The Extension does not share any data with the Extension developer or any third party, with one exception:

• User-configured backend services: When you activate speech capture, audio data is sent to the speech recognition service you have configured. Similarly, transcribed text may be sent to the translation service and TTS service you have configured. The Extension developer has no access to these connections or the data exchanged. The privacy policies of the respective third-party services (Soniox, Google Cloud, DeepL, ElevenLabs, Edge TTS) apply to data processed by those services.

The Extension does not sell, transfer, or use user data for purposes unrelated to its core functionality. The Extension does not use or transfer user data to determine creditworthiness or for lending purposes.

6. Permissions

The Extension requests the following browser permissions, each used solely for its stated purpose:

• tabCapture: Capture audio from browser tabs for speech recognition.
• storage: Save user preferences locally on the device.
• activeTab: Identify the current tab to inject the translator panel.
• offscreen: Create an offscreen document for audio capture (required by Manifest V3).
• scripting: Inject the translator panel into tabs opened before the Extension was installed.

7. Children's Privacy

The Extension is not directed at children under 13 and does not knowingly collect any information from children.
