Privacy Policy

1. Tool Data

All tools on DevTools Hub process data entirely in your browser. When you paste text into the JSON Formatter, generate a UUID, or convert Base64 — that data never leaves your computer. We do not collect, store, transmit, or have access to any data you enter into any tool.

2. Analytics

We use Google Analytics 4 (GA4) to collect anonymous usage data: which pages are visited, how users find the site, and basic device/browser information. This helps us understand which tools are most useful and how to improve the site. GA4 does not collect any data you enter into tools.

3. Cookies

We use a single cookie to remember your theme preference (light or dark mode). This is a functional cookie required for the site to work — it does not track you. GA4 may set additional cookies for analytics purposes.

4. Data Sharing

We do not sell, share, or transfer any user data to third parties. Anonymous analytics data is processed by Google Analytics and subject to Google's privacy policy.
