Privacy Policy

Last updated: 2026-08-14

What this site does with your data

Every tool on Code Utility Hub (JSON formatter, JWT decoder, regex tester, and the rest) runs entirely in your browser. Whatever you paste or type into a tool — including things like JSON payloads, JWTs, or code — is processed locally on your device and is never sent to our servers, logged, or stored by us.

Local storage

We store a single small value in your browser's local storage to remember your light/dark theme preference. It stays on your device and is never transmitted to us.

Advertising

This site may show ads served by Google AdSense. Google and its partners may use cookies and similar technologies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising by visiting Google Ads Settings, or, if you're in the EU/UK, youronlinechoices.eu. Google's use of advertising cookies is governed by Google's own privacy policy.

Analytics

This site may use Google Analytics to understand aggregate usage (which pages are visited, how often) — never the content you type into a tool. Google Analytics uses cookies and may collect your IP address and browser information. You can opt out using the Google Analytics Opt-out Browser Add-on.

Children's privacy

This site is not directed at children under 13 and we do not knowingly collect information from them.

Changes to this policy

If this policy changes — for example, if we add analytics or new ad partners — we will update this page and the "last updated" date above.
