Privacy Policy

Last Updated: April 2, 2026

1. Introduction

At DevTools Studio ("we," "us," or "our"), your privacy is our top priority. We provide a suite of online developer tools designed to be secure, fast, and private. This Privacy Policy explains how we handle your information when you use our website.

2. Data Processing (Client-Side Only)

Crucial Information: Most of our tools (including JSON Formatter, Base64 Encoder, JWT Decoder, and others) perform calculations and conversions **entirely within your browser** using JavaScript.

  • No data entered into our tools is sent to our servers.
  • No data is stored in our database.
  • No data is transmitted to third parties.

When you close the tab, all inputs and outputs are cleared from your browser's temporary memory. We do not have any way to access the text, images, or JSON you process using these utilities.

3. Analytics and Cookies

We use minimal analytics to understand traffic patterns and improve our user experience. This may involve:

  • Anonymous technical information such as browser type, operating system, and pages visited.
  • Aggregation of usage statistics to help us decide which tools to build next.
  • We do not use cookies to track individual users or build personal profiles.

4. Advertising (Google AdSense)

DevTools Studio is a free platform funded by advertising. We use Google AdSense to serve ads. Google may use cookies or similar technologies to serve ads based on your visit to this and other websites. You can opt-out of personalized advertising by visiting Google's Ad Settings.

5. External Links

Our blog and tools may contain links to external sites (e.g., GitHub, documentation sites). We are not responsible for the privacy practices of those third-party websites.
