隐私权政策
适用于浏览器扩展「译览 YiLan」 · 生效日期 2026 年 11 月 6 日
English version below
概述
译览是一个网页翻译扩展。它没有自己的服务器，不要求注册账号，不收集统计数据，也不使用任何第三方统计或广告代码。我们不会出售、出租或交换你的任何数据。
会发送到网络的内容
要翻译的文字会通过 HTTPS 发送到在线翻译服务，用来生成译文。只发送要翻译的文字本身，请求不带 Cookie，也不带来源网页的地址。翻译服务方没有说明如何保存这些数据，请不要用译览翻译密码、证件号码等敏感内容。
文字只在你操作时发送：点击翻译页面、框选、划词翻译、右键菜单翻译，或在弹窗里翻译文本。以下情况例外：
- 你翻译了一个页面后，同一标签页里同一网站的后续页面会继续翻译，直到你点「显示原文」或离开这个网站。
- 你开启了「自动翻译」，或把网站、语言设成「总是翻译」时，符合条件的页面打开后会自动翻译。
- 你把划词设置成「直接翻译」时，选中的文字会立即发送。
输入框
译览默认不读取输入框、文本域和可编辑区域的内容。只有你开启「输入框翻译」，并在某个输入框里连按三下空格时，才会发送这个输入框里要翻译的文字。密码框在任何情况下都不会被读取。
保存在你电脑上的内容
- 设置和术语表：保存在浏览器的同步存储中。如果你登录了浏览器账号并开启同步，浏览器会在你的设备之间同步它们。
- 译文缓存：保存在本机，用来避免重复翻译同样的句子。可以选择不保存，或保存 7、15、30 天，随时可以清空。无痕窗口里的译文不会写入磁盘。
- 最近翻译：弹窗「文本翻译」里最近的 20 条记录保存在本机，可以随时清空。无痕窗口不保存。
这些数据只存在你的浏览器里，不会上传到我们这里。卸载扩展时，浏览器会一并删除它们。
导出图片
把翻译结果保存或复制为图片时，译览会重新下载网页上已经显示的图片和字体，用来生成这张图。图片在本机生成，不会发送给任何服务。

Privacy Policy
For the browser extension “YiLan” · Effective November 6, 2026
Summary
YiLan is a web page translation extension. It has no server of its own, needs no account, collects no analytics, and contains no third-party analytics or advertising code. We do not sell, rent or trade any of your data.
What is sent over the network
Text you ask to translate is sent over HTTPS to an online translation service to produce the translation. Only that text is sent: requests carry no cookies and no address of the page it came from. The translation service does not state how it stores this data, so please do not use YiLan to translate passwords, identity numbers or other sensitive content.
Text is sent only when you act: translating a page, drawing a translation box, translating a selection, using the context menu, or translating text in the popup. The exceptions are:
- After you translate a page, later pages of the same site in the same tab are translated too, until you choose “Show original” or leave the site.
- If you turn on automatic translation, or set a site or language to “Always translate”, matching pages are translated when they open.
- If you set selection translation to “Translate directly”, selected text is sent right away.
Text fields
By default YiLan does not read text fields, text areas or editable regions. Only when you turn on “Input translation” and press space three times in a field is the text to be translated in that field sent. Password fields are never read.
What is stored on your computer
- Settings and glossary: kept in the browser’s sync storage. If you are signed in to your browser with sync turned on, the browser syncs them between your devices.
- Translation cache: kept on your computer so the same sentence is not translated twice. You can turn it off or keep it for 7, 15 or 30 days, and clear it at any time. Nothing from private windows is written to disk.
- Recent translations: the last 20 texts translated in the popup are kept on your computer and can be cleared at any time. Not kept in private windows.
This data stays in your browser and is never uploaded to us. The browser deletes it when you remove the extension.
Exporting images
When you save or copy a translation as an image, YiLan downloads again the images and fonts already shown on the page to draw it. The image is made on your computer and is not sent to any service.

Children
YiLan is not directed at children under 13 and does not knowingly collect personal information from anyone.
