Privacy

Every tool runs in your browser. Nothing you type, paste, or upload ever reaches our servers.

The short version

Utilo is built on a single hard rule: your files, your text, and the values you generate stay on your device. None of it touches a server we operate. This applies to every tool on the site, today and tomorrow.

What never leaves your browser

  • Files you drop in (PDFs, images, anything).
  • Text you paste (JSON, JWTs, passwords, prose).
  • Values the tool generates for you (UUIDs, passwords, hashes, QR codes).
  • Your browsing pattern within a tool — clicks, copies, toggles.

What does cross the network

The site is hosted on Vercel as a static export. Like any website, loading a page sends some technical signals that we use only in aggregate:

  • Page views and referrer via Vercel Analytics — so we know which tools land traffic and from where. Anonymised, no cookies, no fingerprinting, no PII.
  • Core Web Vitals (LCP, INP, CLS, TTFB) via Vercel Speed Insights — performance metrics only, never input contents.
  • Standard server logs kept by the hosting provider for a short window — IP address, user-agent, the URL requested. These are inherent to any website and are not used by us beyond their default retention.

None of these contain anything you type or upload into a tool. The codebase has a hard rule that prohibits passing tool input into analytics, query strings, or any outbound request.

Cookies

Utilo does not set any tracking, advertising, or analytics cookies. The only client-side storage we use is localStorage to remember your theme choice (light or dark). That value never leaves your browser.

Third-party assets

Some tools load open-source libraries (pdf-lib, jsdiff, marked, qrcode, DOMPurify, and similar). These run client-side, are bundled with the page, and never make network calls of their own.

Children

Utilo is not directed at children under 13 and does not knowingly collect any data from them. Because no personal data is collected from any user, there is nothing to delete on request.

Changes

If this policy ever changes — for example, if a future tool needs a narrow new exception — we will update this page and the changelog in the public repository. The core promise (no user-data leaves your device) is the foundation of the product and is not negotiable.
