Open Immersive Translator от Nolan Bryant

语灵灵是一款开源（AGPL-3.0）、隐私优先的双语网页翻译扩展。

🔒 隐私是架构，不是承诺
- 无中间服务器：翻译请求从你的浏览器直接发往所选引擎，我们收不到、也不想收任何数据
- 翻译历史与设置只存在本地浏览器
- 代码完全开源，任何人可审计

🛡 敏感信息脱敏（Beta，业内少有）
开启后，邮箱、电话、银行卡号、身份证号、API Key 会先在本地替换为占位符，再发给翻译引擎，译文返回后本地还原。敏感内容原文永不出浏览器。

🌐 双语对照，就地翻译
- 在你正在阅读的页面上直接生成双语对照，无需复制粘贴、无需上传
- Alt+T 一键开关

⚙ 引擎透明，自由选择
- 免费开箱即用：Google、MyMemory、LibreTranslate（可自托管）
- BYOK 高质量引擎：DeepL / OpenAI / DeepSeek，Key 只存本地

YuLingLing is an open-source (AGPL-3.0), privacy-first bilingual webpage translator.

🔒 Privacy by architecture, not by promise — no middle server: requests go straight from your browser to the engine you choose. History and settings never leave your browser. Fully open source and auditable.

🛡 Sensitive-data masking (Beta): when enabled, emails, phone numbers, card numbers, national IDs and API keys are replaced with placeholders locally before translation and restored locally after. Originals never leave your browser.

🌐 Bilingual, in place: side-by-side translation on the page you are reading — no copy-paste, no uploads. Toggle with Alt+T.

⚙ Transparent engines, your choice: free out of the box (Google, MyMemory, LibreTranslate); BYOK premium (DeepL / OpenAI / DeepSeek), keys stored locally only.
