隐私政策

最后更新：2026年10月26日

Momo工具箱（以下简称"我们"）非常重视您的隐私。本隐私政策说明我们在您使用本网站（www.web-tools.top）时如何处理数据。

核心承诺：工具数据本地处理

本网站的所有工具（包括但不限于 JSON 格式化、Markdown 编辑器、二维码生成、密码生成器、哈希计算等）均在您的浏览器本地处理数据。

  • 您输入到工具中的内容永远不会发送到我们的服务器
  • 所有计算、转换、生成都在您的设备上完成
  • 我们不通过工具收集您处理的任何内容数据
  • 个别工具（AI 抠图）需要从第三方 CDN 下载模型与运行时资源，但您的图片和输入内容不会被上传

本地存储（localStorage）

为了提供更好的体验，我们使用浏览器本地存储保存以下偏好设置，这些数据仅存在于您的设备上：

  • 语言偏好（momo-lang）：记录您选择的中/英文界面
  • 主题偏好（momo-theme）：记录您选择的明/暗主题
  • 收藏工具（momo-starred）：记录您收藏的工具列表

您可以随时通过浏览器设置清除这些数据，不会影响网站的正常使用。

Cookie 与类似技术

工具本身不使用 Cookie。第三方分析与广告服务（Google Analytics、Google AdSense）会在您访问时设置 Cookie 或读取设备标识；语言、主题、收藏等偏好保存在浏览器 localStorage 中，不会随请求发送。

您可以通过浏览器设置清除或阻止 Cookie，也可以在 Google 广告设置 中关闭个性化广告。阻止 Cookie 不影响工具本身的使用。

网站流量分析

我们通过以下三种方式了解访问情况与页面性能，目的均为改进站点：

  • Cloudflare Web Analytics：不写入跟踪 Cookie，仅提供聚合访问统计，详见 Cloudflare 隐私政策。
  • Google Analytics 4：通过 Cookie（如 _ga）统计页面浏览、访问来源、设备信息与大致地区。Google 声明其不存储完整 IP 地址。您可安装 Google Analytics 停用插件 选择退出。
  • 自建 Web Vitals 上报：页面会向我们的 Cloudflare Worker（momo-vitals.wecccfk.workers.dev）发送性能指标（LCP、CLS、INP、FCP、TTFB）、页面路径、User-Agent 与时间戳，用于定位性能问题。该数据不包含您在工具中输入的任何内容。

AI 抠图的模型下载

AI 抠图使用 ISNet 模型在您的浏览器本地推理。首次使用时会从 IMG.LY 的 CDN（staticimgly.com）下载模型与 WebAssembly 运行时（约 40–80MB），并缓存在浏览器 IndexedDB 中；这些请求会像普通网页资源请求一样向该 CDN 暴露 IP 等连接信息。您的图片不会上传到该 CDN 或我们的服务器。

第三方服务

本网站使用以下第三方服务，它们有各自独立的隐私政策：

  • Cloudflare：网站托管、CDN 加速、Web Analytics 与性能上报 Worker。Cloudflare 可能会处理您的 IP 地址用于网络传输和聚合统计，详见 Cloudflare 隐私政策。
  • Google Fonts：网页字体加载，Google 可能会收集您的 IP 地址和请求信息，详见 Google 隐私政策。
  • Google Analytics（Google LLC）：流量统计，详见 Google 隐私政策。
  • Google AdSense（Google LLC）：广告投放，详见 Google 广告政策。
  • IMG.LY：提供 AI 抠图模型与运行时资源（staticimgly.com），详见 IMG.LY 隐私政策。

广告

本网站使用 Google AdSense 展示广告以维持运营。Google 及其合作伙伴可能使用 Cookie（包括 DoubleClick Cookie）根据您在本站及其他网站的访问记录投放个性化广告，并衡量广告效果。

  • 广告位与工具操作区域分离，不读取、不关联您在工具中输入的内容
  • 您可在 Google 广告设置 关闭个性化广告，或通过 aboutads.info 管理第三方广告 Cookie
  • 工具核心功能保持免费，广告是维持站点运营的收入来源

儿童隐私

本网站面向一般用户，并非针对 13 岁以下儿童设计，也不会主动收集儿童的个人信息。若您认为儿童向我们提供了个人信息，请通过下方邮箱联系我们，我们会尽快删除。

数据安全

由于您的工具数据从未离开您的设备，数据安全完全由您掌控。我们建议您使用现代浏览器并保持系统更新。

政策变更

我们可能会不时更新本隐私政策。更新后，我们会在本页面发布新版本并更新"最后更新"日期。我们鼓励您定期查阅本页面以了解任何变更。

如果您对本隐私政策有任何疑问，请通过邮箱联系我们：[email protected]。

Momo Toolbox ("we") takes your privacy seriously. This Privacy Policy explains how we handle data when you use this website (www.web-tools.top).

Core Promise: Local Tool Processing

All tools on this website (including but not limited to JSON formatter, Markdown editor, QR code generator, password generator, hash calculator, etc.) process data locally in your browser.

  • Content you enter into the tools is never sent to our servers
  • All computation, conversion, and generation happen on your device
  • We do not collect any content data you process with the tools
  • One tool (AI background removal) downloads model/runtime assets from a third-party CDN, but your images and inputs are never uploaded

Local Storage (localStorage)

To provide a better experience, we use browser local storage to save the following preferences. This data exists only on your device:

  • Language preference (momo-lang): remembers your chosen UI language
  • Theme preference (momo-theme): remembers your light/dark theme choice
  • Starred tools (momo-starred): records your favorite tools

You can clear this data anytime via your browser settings without affecting normal use of the site.

Cookies and Similar Technologies

The tools themselves do not use cookies. Third-party analytics and advertising services (Google Analytics, Google AdSense) may set cookies or read device identifiers when you visit. Language, theme and favorites preferences are stored in browser localStorage and are not sent with requests.

You can clear or block cookies in your browser settings, or turn off personalized advertising in Google Ads Settings. Blocking cookies does not affect the tools themselves.

Traffic Analytics

We use the following three methods to understand traffic and page performance, all for improving the site:

  • Cloudflare Web Analytics: no tracking cookies; aggregate traffic statistics only. See the Cloudflare Privacy Policy.
  • Google Analytics 4: uses cookies (such as _ga) to measure page views, referrers, device information and approximate region. Google states that it does not store full IP addresses. You can opt out with the Google Analytics Opt-out Browser Add-on.
  • Self-hosted Web Vitals reporting: pages send performance metrics (LCP, CLS, INP, FCP, TTFB), page path, User-Agent and timestamp to our Cloudflare Worker (momo-vitals.wecccfk.workers.dev) to help diagnose performance. This data does not include anything you enter into the tools.

AI Background Removal Model Downloads

AI background removal runs the ISNet model locally in your browser. On first use, the model and WebAssembly runtime (~40–80MB) are downloaded from IMG.LY's CDN (staticimgly.com) and cached in your browser's IndexedDB. These requests expose connection information such as your IP address to that CDN, as any ordinary web asset request would. Your images are never uploaded to that CDN or to our servers.

Third-Party Services

This website uses the following third-party services, each with its own privacy policy:

  • Cloudflare: hosting, CDN acceleration, Web Analytics and the performance-reporting Worker. Cloudflare may process your IP address for network transit and aggregate stats. See Cloudflare Privacy Policy.
  • Google Fonts: web font loading. Google may collect your IP address and request information. See Google Privacy Policy.
  • Google Analytics (Google LLC): traffic statistics. See Google Privacy Policy.
  • Google AdSense (Google LLC): advertising. See Google Advertising Policies.
  • IMG.LY: provides AI background removal model and runtime assets (staticimgly.com). See IMG.LY Privacy Policy.

Advertising

This website uses Google AdSense to display ads that keep the service running. Google and its partners may use cookies (including the DoubleClick cookie) to serve personalized ads based on your visits to this and other websites, and to measure ad performance.

  • Ad units are separated from tool controls and never read or associate with what you enter into the tools
  • You can disable personalized advertising in Google Ads Settings, or manage third-party ad cookies at aboutads.info
  • Core tool functionality remains free; advertising is the revenue source that keeps the site running

Children's Privacy

This website is intended for a general audience and is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us at the email below and we will delete it.

Data Security

Since your tool data never leaves your device, data security is entirely under your control. We recommend using a modern browser and keeping your system up to date.

Policy Changes

We may update this Privacy Policy from time to time. When updated, we will publish the new version on this page and update the "Last updated" date. We encourage you to review this page periodically for any changes.
