Privacy Policy
Last updated: January 22, 2025
Your Privacy Matters
JSON Parser is designed with privacy-first principles. We believe your data is yours, and we've built our tool to ensure it stays that way.
100% Client-Side Processing
Zero Server Upload
All JSON processing happens in your browser. When you paste, upload, or edit JSON data, it never leaves your computer. There is no server-side processing, no backend storage, and no data transmission to our servers.
How it works: Our JSON parser uses JavaScript running directly in your browser. The Monaco Editor, jsTree visualization, and all conversion tools operate entirely on your device.
What We Don't Collect
- Your JSON data or file contents
- Uploaded files or parsed results
- Personal information or contact details
- IP addresses or device identifiers (beyond standard analytics)
- Cookies for tracking across websites
What We Do Collect (Analytics Only)
To improve our service, we use Google Analytics to collect:
- Anonymous usage statistics: Page views, session duration, and feature usage
- Basic device info: Browser type, screen resolution, language preference
- Geographic data: Country/region (not precise location)
You can opt-out: Use browser extensions like uBlock Origin, Privacy Badger, or enable "Do Not Track" in your browser settings.
Google AdSense
We display ads via Google AdSense to keep this service free. AdSense may use cookies to show personalized ads based on your browsing history. You can control ad personalization through your Google Ads Settings.
Share via URL Feature
When you use the "Share" button, your JSON data is encoded in the URL (using URL encoding, not base64). This means:
- The JSON is stored in your browser's address bar, not on our servers
- Anyone with the URL can see your JSON data
- Don't share URLs containing sensitive information (passwords, API keys, personal data)
Third-Party Services
We use the following external services:
| Service | Purpose | Privacy Policy |
|---|---|---|
| Google Analytics | Anonymous usage analytics | Link |
| Google AdSense | Display ads to keep service free | Link |
| CDN Providers (jsDelivr, Cloudflare) | Fast delivery of CSS/JS libraries | Standard CDN practices (no data collection from our side) |
Data Retention
We don't store any of your data. When you close the browser tab, your JSON data is deleted from memory. Even if you use "Share via URL", the data only exists in the URL itself, not on our servers.
Security
Since we don't store your data, there's no server-side risk of data breaches. However, we still implement security best practices:
- HTTPS encryption: All traffic is encrypted via SSL/TLS
- XSS protection: All user input is properly escaped to prevent injection attacks
- No file uploads to server: Files are read directly in your browser using the FileReader API
- Content Security Policy: Restricts execution of malicious scripts
Children's Privacy
Our service does not knowingly collect information from children under 13. Since we don't collect personal data at all, this service can be used by anyone without privacy concerns.
Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date. Continued use of the service after changes constitutes acceptance of the new policy.

Summary
TL;DR: Your JSON data never leaves your browser. We use Google Analytics for anonymous usage stats and AdSense for ads. No data storage, no server uploads, no tracking cookies. Privacy-first, always.
