LingoFlow Privacy Policy · 隐私政策

Last updated: September 11, 2026   |   Effective date: July 8, 2026

1. Overview

LingoFlow is a browser extension that helps you read foreign-language websites. This Privacy Policy explains how (and how little) we handle your data.

2. Data We Collect

We do not collect any personal data.

3. Local Storage

All data stays in your browser's local storage (chrome.storage.local):

This data never leaves your device. You can delete it at any time by clearing the extension data from Chrome's extension management page.

4. API Keys

LingoFlow supports optional integration with third-party translation APIs. When you provide an API key:

5. Third-Party Services

When you use translation features with an external engine enabled, the selected text is sent directly to the corresponding translation service provider's API endpoint for processing. The specific service depends on which engine you have configured. Please review each service provider's own privacy policy for details on how they handle translation requests.

Offline Dictionary (no data transmitted)

LingoFlow bundles an offline English–Chinese dictionary (derived from ECDICT, MIT licensed) inside the extension. Single-word lookups are resolved locally on your device — no network request is made and no data leaves your browser.

Online Dictionary Fallback

If a word is not found in the offline dictionary, LingoFlow may send only that word to one of the following online sources, depending on your settings:

Only the queried word is transmitted. LingoFlow never sends page content, browsing history, or any identifiers along with these requests.

6. Children's Privacy

LingoFlow does not knowingly collect personal information from children under 13 years of age.

7. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.

8. Contact

If you have questions about this Privacy Policy, please open an issue on our GitHub repository or contact us through the support channel provided in the extension settings.

离线词典(不传输任何数据)

LingoFlow 在扩展内打包了一份离线英汉词典(基于 ECDICT,MIT 协议)。查询单个单词时会在你的设备本地完成解析——不发起网络请求,也没有任何数据离开你的浏览器。

在线词典兜底
