Privacy Policy

Data Processing

All tools on WUS process data entirely in your browser using JavaScript and WebAssembly. No text, files, images, or other data you input into any tool is ever transmitted to our servers. Your data never leaves your device.

Information We Collect

We collect minimal anonymous usage data through third-party services:

  • Google Analytics — anonymized page view data to understand which tools are most used
  • Vercel Speed Insights — performance metrics to improve site speed
  • Google AdSense — privacy-respecting advertisements that support the site

We do not collect names, email addresses, IP addresses (beyond what analytics services automatically capture), or any personally identifiable information unless you voluntarily submit it through our feedback form.

Cookies

We use minimal cookies required for analytics and ad personalization. You can control cookie preferences through your browser settings. Blocking cookies will not affect tool functionality since all tools run client-side.

Third-Party Services

We use the following third-party services:

  • Google Analytics — anonymized traffic analysis
  • Google AdSense — privacy-respecting advertisements
  • Vercel — hosting and performance insights

Each service operates under its own privacy policy. We do not share your data with any other third parties.

Google AdSense & Ad Personalization

We use Google AdSense to serve advertisements that help keep this tool free. Google AdSense uses cookies to serve ads based on your prior visits to our website and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and/or other sites on the internet.

Opt out of personalized ads: You can opt out of personalized advertising by visiting Google Ads Settings. Alternatively, you can opt out of some third-party vendors' use of cookies for personalized advertising by visiting www.aboutads.info.

We do notplace ads on thin variant pages, auto-generated pages with <800 words of content, or pages with a quality score below 0.85. Ads only appear on pages with substantial, useful content.

Cookie Consent

We display a cookie consent banner on your first visit. You can accept or decline cookies used for analytics and ad personalization. Your choice is stored locally in your browser and is never transmitted to our servers. Declining cookies will not affect tool functionality — all tools run entirely client-side.

Data Security

Because all tool processing occurs client-side, there is no data storage, transmission, or processing of user content on our servers. This architecture inherently protects your sensitive information including API keys, passwords, code, and personal documents.
