我们收集哪些数据Information We Collect
本插件在你使用时，会读取你在 web.whatsapp.com 页面上的部分聊天内容：对方发来的消息文本，以及你在输入框中输入的、准备翻译或润色的文本。插件不会读取除 web.whatsapp.com 以外任何网站的内容，也不记录你的浏览历史。
While in use, the extension reads a portion of the chat content on web.whatsapp.com: incoming message text, and any text you type into the compose box for translation or polishing. It does not read content on any site other than web.whatsapp.com, and it does not log your browsing history.
数据如何使用与传输How Data Is Used and Transferred
本插件的核心功能是翻译与文本润色。为实现这一功能，你需要翻译或润色的文本会被发送至以下第三方服务，具体使用哪一个取决于你的设置和各服务当时的可用性： The extension's core function is translation and text polishing. To provide this, the text you translate or polish is sent to one of the following third-party services, depending on your settings and each service's availability at the time:
默认免费翻译源（无需配置）Default free translation sources (no setup required)
Google 翻译、Microsoft Bing 翻译、MyMemory —— 用于自动翻译收到的消息，以及默认的发送前翻译。Google Translate, Microsoft Bing Translator, and MyMemory — used for auto-translating incoming messages and default pre-send translation.
可选翻译源（需你自行配置密钥）Optional translation sources (require your own credentials)
- DeepL（需 DeepL Authentication Key）DeepL (requires a DeepL Authentication Key)
- 百度翻译开放平台（需 APPID 与密钥）Baidu Translate Open Platform (requires an App ID and secret key)
- 腾讯云机器翻译（需 SecretId 与 SecretKey）Tencent Cloud Machine Translation (requires a SecretId and SecretKey)
你自定义配置的 AI 润色服务商Your own configured AI polishing provider
如果你配置了 OpenAI、DeepSeek 或其他兼容服务商（包括本地部署的 Ollama），需要润色的文本将直接发送至你配置的服务商地址。If you configure OpenAI, DeepSeek, or another compatible provider (including a locally hosted Ollama instance), the text to be polished is sent directly to the endpoint you configured.
本插件的所有网络请求均由你的浏览器（通过后台 Service Worker，仅用于规避浏览器 CORS 限制）直接发往上述服务商。开发者不运营任何中间服务器，不会收集、截取、存储、分析或以任何形式留存你的聊天记录或翻译内容。 Every request the extension makes goes directly from your browser (via a background service worker, used solely to work around browser CORS restrictions) to the providers above. The developer operates no intermediary server and does not collect, intercept, store, analyze, or otherwise retain your chats or translations in any form.
API 密钥的存储Storage of API Keys
你在设置页面输入的任何密钥（DeepL Auth Key、百度 APPID / 密钥、腾讯云 SecretId / SecretKey、OpenAI 等 AI 服务商 API Key），均仅保存在 Chrome 浏览器的本地存储（chrome.storage.local）中，只存在于当前安装本插件的这台设备上。这些密钥不会被上传到开发者的服务器，也不会通过 Chrome 账号云端同步到你的其他设备。
Any key you enter in the settings page — DeepL Auth Key, Baidu App ID / secret key, Tencent Cloud SecretId / SecretKey, or an AI provider API key such as OpenAI's — is stored only in the Chrome browser's local storage (chrome.storage.local), on the single device where the extension is installed. These keys are never uploaded to any developer-run server, and never synced to your other devices via your Chrome/Google account.
功能设置的同步Settings Sync
部分不涉及密钥的开关类设置（如是否自动翻译、目标语言、译文颜色等）使用 chrome.storage.sync 保存，这类设置会通过你登录的 Google 账号在你已登录同一账号的多台设备间同步——这是 Chrome 浏览器提供的标准同步机制，本插件开发者无法访问该同步数据。该同步范围不包含任何 API Key 或聊天内容。
Non-sensitive toggle-style settings that don't involve any key (such as whether auto-translation is on, your target language, or translation text color) are saved with chrome.storage.sync. This lets these settings follow you across devices signed into the same Google account, using Chrome's standard built-in sync mechanism — the extension developer cannot access this synced data. No API key or chat content is ever included in this sync.
