Privacy Policy

The short version: your data never leaves your browser. Here is the long version — and how to verify it yourself.

Everything runs in your browser

Every tool on NexusTools processes your input locally, using standard browser APIs (Canvas, Web Crypto, native JavaScript). When you format JSON, generate a password, compress an image, or decode a JWT, that data is handled entirely on your device. There is no backend server receiving your input — the pages you load are static files, and the processing happens in your browser's memory. Close the tab, and the data is gone.

✓ Don't take our word for it: open your browser's DevTools (F12), go to the Network tab, and use any tool. You will see no network requests carrying your data — only the initial page load of static assets.

Analytics: anonymous and cookie-free

We use a self-hosted instance of Umami, a privacy-focused analytics tool, to count page visits. It stores no cookies, collects no personal information, and cannot track you across sites. It records only aggregate data: which pages are visited, from which country, and with which browser type. This helps us decide which tools to build next. Umami is open source and GDPR-compliant by design.

The exceptions (full disclosure)

Two tools contact external services, and only when you explicitly use them:

  • IP Geolocation queries ipapi.co with the IP address you enter (or your own, if you ask for it) — that lookup is subject to ipapi.co's privacy policy
  • Favicon Generator loads font files from fonts.googleapis.com when you pick a Google Font — Google may log that request (your IP and user agent); the text you type never leaves your browser. The site's own typography is self-hosted and makes no Google request.

No accounts, no tracking, no ads (yet)

NexusTools requires no registration and stores no user profiles. We do not sell data — we have none to sell. If we ever add advertising to keep the site free, it will be clearly visible, and this policy will be updated with exactly what changes.

Verify it: the code is open source

The entire site is open source. You can read the code of every tool, confirm there are no hidden network calls, and even run the site yourself: github.com/nexustools-dev/nexus-tools
