Privacy Policy
Last Updated: September 2026
1. Client-Side Data Architecture
At DevTools Lab (a service by API Test Lab accessible at devtools.apitestlab.org), we prioritize user privacy. All developer utilities—including the JSON to TypeScript converter, SQL formatter, JWT debugger, Regex tester, and Base64 encoder—execute entirely in your browser using client-side JavaScript. We do not transmit, log, or store your inputs on remote servers.
2. Google AdSense & Third-Party Cookies
We use Google AdSense to serve advertisements on our website. Google, as a third-party vendor, uses cookies (such as the DoubleClick cookie) to serve ads to users based on their visits to this and other websites. You may opt out of personalized advertising by visiting Google's Ads Settings.
3. Server Logs & Analytics
Our web servers automatically record standard HTTP request information (such as your IP address, browser type, referring page, and timestamp) for diagnostic, security, and traffic monitoring purposes.
4. Contact Information
If you have questions regarding this Privacy Policy, you can reach out via email at contact@apitestlab.org or visit our main portal at apitestlab.org.
