PRIVACY

Privacy Policy

This page explains how uTranslate Live handles data when you use the Chrome extension.

Effective date: July 26, 2026 · Product: uTranslate Live Chrome extension · Publisher: uTranslate · Contact: chrome-live@utranslate.net

English

1. Summary

  • With your permission, the extension may capture audio that is playing in the current Chrome tab so it can provide real-time transcription and bilingual captions.
  • We do not retain your voice audio after it is processed for that caption session, and we do not sell your voice audio or the speech content derived from it.
  • For service reliability we record only necessary operational metrics: character counts, language, latency, and error categories.

2. Who we are

The publisher and data controller is uTranslate. This Privacy Policy applies to the uTranslate Live Chrome extension and the related caption service endpoints used by that extension.

Hosts used for captions after you start a live session:

  • slm.utranslate.net — caption API entry (session control and caption results)
  • slm-demo.beithing.com — production API backend reached via redirect from the entry host
  • live.x.eletker.com — primary encrypted real-time audio transport (WebRTC / WSS) for the caption session
  • slm-4rm05o6s.livekit.cloud — backup encrypted real-time audio transport used only if the primary media host is unavailable

Questions about this policy: write to chrome-live@utranslate.net.

3. Permission and consent

Tab audio is processed only after you take an affirmative action in the extension UI (for example, starting live captions). If you do not start a live session, the extension does not capture or transmit tab audio.

You can stop processing at any time by stopping the live session or closing the on-page caption overlay. Stopping ends the active capture session and cleans up the related session resources.

4. What we process

4.1 Tab audio (with your permission)

When live captions are running, the extension captures audio from the active tab and streams it to our caption service so the speech can be transcribed and translated in near real time. Captions are returned to your browser for display.

Retention: voice audio used for a caption session is processed to provide that feature and is not retained as a stored voice archive after the session work is complete.

Sale: we do not sell your voice audio, transcripts, translations, or other speech-derived content to third parties.

4.2 Operational metrics we keep

To operate and improve reliability of the caption service, we may record:

  • Character counts (for example, transcript / translation length)
  • Language (detected source language and/or selected target language)
  • Latency (timing needed to measure responsiveness)
  • Error categories (non-content failure classes such as timeout, validation, or connectivity)

These metrics are content-free operational signals. They are not used to rebuild or republish your speech.

4.3 Data kept on your device

The extension may store local preferences (for example, target language and caption style) and short-lived session state needed to show captions. Tab title and URL used in the popup UI remain on your device for that session and are not sent as part of the caption request payload.

5. How we use data

  • Provide real-time bilingual captions for the current tab’s audio
  • Maintain service reliability and diagnose failures using the metrics above
  • Respond to support requests you choose to send by email

We do not use tab audio or speech-derived content for advertising, resale, or unrelated profiling.

6. Sharing and processors

Audio is transmitted only as needed to provide captions, over encrypted connections (HTTPS / WSS / WebRTC). The hosts listed in section 2 act as processors for this single purpose: the API hosts orchestrate the session and return captions; the media hosts carry the live audio stream for transcription and translation only.

We do not sell personal data. Transfers of user data are limited to what is necessary to provide or improve the disclosed caption feature, to comply with law, or to protect security.

7. Chrome Web Store Limited Use

uTranslate Live’s use of user data is limited to providing or improving the extension’s single purpose: real-time bilingual captions for audio playing in the current Chrome tab. We handle user data securely, do not sell it, and do not use it for prohibited secondary purposes such as unrelated advertising.

8. Your choices

  • Do not start live captions if you do not want tab audio processed
  • Stop an active session to end capture immediately
  • Uninstall the extension to remove its local stored preferences
  • Contact chrome-live@utranslate.net with privacy questions

9. Changes

If our data practices change in a material way, we will update this page and the effective date. For Chrome Web Store users, material changes to data handling will also be reflected in the listing’s privacy disclosures as required.

1. 摘要

  • 在您许可后,扩展可读取当前 Chrome 标签页正在播放的音频,用于实时转写与双语字幕。
  • 我们不会在字幕处理完成后继续保留您的语音音频,也不会出售您的语音及其相关内容数据。
  • 我们仅记录必要的运维指标:字符数、语言、时延与错误分类。

2. 发布者与适用范围

发布者及数据控制者为 uTranslate。本隐私政策适用于 uTranslate Live Chrome 扩展,以及该扩展调用的字幕服务端点。

您开始实时字幕后,扩展会使用以下主机:

  • slm.utranslate.net — 字幕 API 入口(会话控制与字幕结果)
  • slm-demo.beithing.com — 由入口主机跳转到达的生产 API 后端
  • live.x.eletker.com — 主用加密实时音频传输(WebRTC / WSS)
  • slm-4rm05o6s.livekit.cloud — 备用加密实时音频传输(仅在主用媒体主机不可用时使用)

如有疑问,请联系 chrome-live@utranslate.net。

3. 许可与同意

仅在您在扩展界面中主动开始实时字幕后,才会捕获并传输标签页音频。若您未开始会话,扩展不会读取或上传标签页音频。

您可随时停止会话,或关闭页面字幕层以结束捕获并清理当前会话资源。

4. 我们处理哪些数据

4.1 标签页音频(经您许可)

实时字幕运行期间,扩展会捕获当前标签页音频并流式传输至字幕服务,以便近实时完成转写与翻译,再将字幕返回到您的浏览器显示。

保留:用于字幕会话的语音音频仅用于提供该功能,会话处理完成后不会作为语音存档继续保留。

出售:我们不会出售您的语音音频、转写文本、翻译文本或其他由语音衍生的内容。

4.2 我们保留的运维指标

为保障服务稳定,我们可能记录:

  • 字符数(如转写 / 翻译长度)
  • 语言(检测到的源语言和 / 或您选择的目标语言)
  • 时延(用于衡量响应速度)
  • 错误分类(不含内容的失败类别,如超时、校验失败、连接异常等)

上述指标为不含语音内容的运维信号,不会用于重建或公开您的语音内容。

4.3 保留在您设备上的数据

扩展可能在本地保存偏好设置(如目标语言、字幕样式)以及展示字幕所需的短期会话状态。弹窗中使用的标签页标题与网址仅保存在本机会话中,不会作为字幕请求正文发送。

5. 如何使用数据

  • 为当前标签页音频提供实时双语字幕
  • 使用上述指标维护服务可靠性并排查故障
  • 处理您主动发送的支持邮件

我们不会将标签页音频或语音衍生内容用于广告、转售或无关画像分析。

6. 共享与处理方

音频仅在提供字幕所必需的范围内传输,并通过加密连接(HTTPS / WSS / WebRTC)进行。第 2 节所列主机仅作为实现该单一用途的处理方:API 主机负责会话编排并返回字幕;媒体主机仅承载用于转写与翻译的实时音频流。

我们不出售用户数据。用户数据转移仅限于提供或改进已披露的字幕功能、遵守法律法规,或保障安全所必需的情形。

7. Chrome 网上应用店有限使用

uTranslate Live 对用户数据的使用仅限于提供或改进扩展的单一用途: 为当前 Chrome 标签页正在播放的音频提供实时双语字幕。 我们会安全处理用户数据,不出售,也不将其用于无关广告等被禁止的次要用途。

8. 您的选择

  • 若不希望处理标签页音频,请不要开始实时字幕
  • 停止会话即可立即结束捕获
  • 卸载扩展可移除其本地偏好设置
  • 隐私相关问题请联系 chrome-live@utranslate.net

9. 变更

若数据处理方式发生实质性变更,我们将更新本页及生效日期。对于 Chrome 网上应用店用户,相关变更也会按要求同步到商品详情中的隐私披露。
