Privacy Policy

What data I collect

None that identifies you. urltoolskit.org is a static site. Every tool on this domain — the URL utilities listed in the footer — processes your input entirely in your browser using JavaScript. Nothing you paste, drop, or build is transmitted to my servers, because there are no servers handling your input.

You can verify this yourself in the browser's Network tab — load any tool page, then paste URLs into it. After the initial page load there are no further network requests. The one exception is when a tool legitimately needs an in-browser library (jsDelivr) or, for the favicon preview tool, when you ask the browser to render <img> tags pointing at third-party favicon services. Both are visible in Network.

What I don't do

• No accounts. The tools never ask you to register, and none of them work differently if you stay anonymous.
• No analytics scripts (no Google Analytics, no Plausible, no Mixpanel, no Hotjar).
• No tracking cookies. The site does not set any cookies at all.
• No advertising pixels.
• No selling or sharing your data with anyone. If you give us an email address it is used to reply to you about what you asked for, and for nothing else.

Third parties that see your IP

Your browser loads a few assets from third-party CDNs so the site stays small and fast. Those hosts necessarily see your IP address:

• Google Fonts — fonts.googleapis.com and fonts.gstatic.com, for the Geist and JetBrains Mono fonts.
• jsDelivr — cdn.jsdelivr.net, for the small libraries (qrcode for the QR tool, psl for the eTLD+1 extractor) loaded on demand by the relevant tool pages.
• Favicon services — if you use the Favicon URL builder, the preview row renders <img> tags pointing at Google S2, DuckDuckGo, and Icon Horse. Those services see your IP and the domain you asked about (because your browser fetches the icon directly).
• Your hosting provider (for urltoolskit.org) can see standard web-server access logs: IP, user-agent, URL, timestamp. I don't use these logs for anything beyond debugging outages and keep them only as long as the host retains them by default.

None of those third parties see the URLs you process inside the tools, because the content never leaves your browser. The library files are static JavaScript downloads.

Local storage

A few tools optionally save data to your browser's localStorage — your light / dark theme preference, the UTM builder's recent-history list, the URL builder's saved templates, and the URL explainer's custom-parameter glossary. All of this stays on your device; nothing is synced anywhere. Clear it from the browser dev-tools or the site's per-tool "Clear history" button any time.

If you give us your email

Some pages offer a form to hear about an offline version, an API, or licensing. It is optional, it is never required to use any tool, and no tool behaves differently if you ignore it.

If you do submit it, we store:

• The address itself, what you asked about, and the page you asked from.
• The date, and the exact consent wording you agreed to.
• A salted hash of your IP address — never the address itself — to show the consent was genuine and to stop the form being flooded.

We email you about the thing you asked about, and nothing else. Your address is never sold, rented, or shared with a third party. Every email carries an unsubscribe link, and you can ask us to delete the record at any time by writing to the address below — we will, without asking why.
