Privacy Policy

Last updated: April 23, 2026

1. Information Collection and Use

At JSON Viewer, your privacy and data security are our highest priorities. Because our tool is built specifically for developers handling sensitive backend data, we have designed our entire architecture around 100% client-side processing.

2. Local Data Processing

We do not collect, store, or transmit your JSON data.

When you paste or fetch JSON data into our editor, all formatting, minification, and validation are performed locally within your browser using JavaScript. Your data never leaves your device and is never sent to any external servers. Once you close the tab, the data is entirely cleared from your active memory.

3. Local Storage

We may use your browser's local storage capabilities (localStorage) exclusively to temporarily save your UI preferences, such as selected themes, editor settings, or recently used configurations. This information remains strictly on your device to enhance your user experience upon returning to the site.

4. Third-Party Analytics

We may use standard, privacy-focused third-party analytics services to understand how visitors interact with our website. These services only collect non-personally identifiable information, such as general geographic regions, browser types, and page views, to help us identify bugs and improve the tool's performance.

5. Contact Us

If you have any questions or concerns regarding this Privacy Policy or how your data is handled while using our tools, please feel free to reach out via our official contact page.
