Privacy Policy

DevUtils (“we” or “our site”) is a collection of free, privacy-friendly online developer tools available at devutils.run. This policy explains how your information is handled when using our services.

1. Tools run in your browser

Most tools (JSON Formatter, Base64, Hash Generator, JWT Decoder, Regex Tester, etc.) run 100% locally in your browser using client-side JavaScript. Your text and files are never sent to or stored on any server.

2. Tools that contact third-party services

Some network-related tools (such as DNS Lookup, My IP, etc.) communicate with external third-party services to perform their functions. That data is processed solely for the calculation and is not stored.

3. Cookies and local storage

We use cookies and your browser’s local storage to remember preferences such as your language, sidebar state, and favorite tools. The Google services described below (analytics and advertising) may also set cookies. You can block or delete cookies in your browser settings, although some features may not work as expected.

4. Analytics (Google Analytics)

We use Google Analytics to understand how the site is used and to improve it. Google Analytics uses cookies to collect non-identifying usage data such as pages visited, time on site, browser and device information, and approximate location. The content you enter into our tools is never collected. See how Google uses data from sites that use its services, and you can opt out with the Google Analytics opt-out browser add-on.

5. Advertising (Google AdSense)

We display ads served by Google AdSense to keep this site free. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google’s use of advertising cookies (including the DoubleClick cookie) enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings, or opt out of third-party vendors’ use of cookies for personalized advertising at www.aboutads.info. Learn more in Google’s advertising policies.
