UtilityLab is designed with a simple principle: your data belongs to you and never leaves your device. All tools process data entirely in your browser using client-side JavaScript. We do not collect, store, transmit, or have access to any data you input into our tools.
We do not collect any personal information. We do not use cookies, tracking scripts, analytics services, or fingerprinting technologies. We have no user accounts, no login system, and no way to identify individual visitors.
Each tool on UtilityLab is a static web page containing JavaScript that runs entirely in your browser. When you upload a file, paste text, or adjust a setting, that data stays in your browser's memory. No information is sent to any server. When you close the page, all session data is permanently cleared.
UtilityLab is hosted on Cloudflare, which processes network requests for the sole purpose of delivering static files. Cloudflare's privacy policy governs network-level data handling. We do not use any third-party analytics, advertising networks, or content delivery networks that track users — with the exception of Google AdSense, which may place cookies for ad personalization. You can manage ad personalization settings through your Google Account.
Our tool pages link to relevant resources and other tools on UtilityLab. We are not responsible for the privacy practices of external websites.
If this policy changes, the updated date at the top of this page will be revised. Continued use of the site after changes constitutes acceptance of the updated policy.
