Privacy Policy
We built JSON Parser Online with privacy as a core principle. This page explains exactly what data we collect — and why the answer is essentially nothing.
Last updated: June 2026 · Effective immediately1. Who We Are
JSON Parser Online (onlinejsonparser.com) is a free developer tool for parsing, formatting, validating and exploring JSON data. The site is operated independently and is not affiliated with any company or organisation.
For questions about this policy, contact us at: support@onlinejsonparser.com
2. Data We Do Not Collect
We do not collect, store, transmit or process any of the following:
- Your JSON data or any content you paste into the tool
- Your name, email address or any personal identifiers
- Your IP address
- Browser fingerprints or device identifiers
- Usage analytics, click tracking or behaviour data
- Any form of telemetry
3. How the Tool Works — 100% Client-Side
JSON Parser Online is a static website. All JSON parsing, formatting, validation and tree rendering is performed entirely within your browser using JavaScript. No data is ever sent to a server.
When you paste JSON into the tool, it is processed locally on your device and never transmitted across the internet. This makes it safe to use with sensitive data such as API keys, authentication tokens, database exports and private configuration files.
4. Local Storage
The only data stored by this site is your theme preference (e.g. Dark, Monokai, Nord), saved in your browser's localStorage. This data:
- Never leaves your device
- Is never transmitted to any server
- Contains no personal information
- Can be cleared at any time by clearing your browser's site data
No cookies of any kind are set by this website.
5. Third-Party Services
Google Fonts
This site loads fonts (Syne and JetBrains Mono) from Google Fonts. When your browser requests these fonts, Google may log the request including your IP address. This is governed by Google's Privacy Policy. No font data is linked to your identity or your use of this tool.
Buy Me a Coffee (Optional)
The site includes a voluntary donation link to buymeacoffee.com. This link only activates if you choose to click it. If you do, you will be taken to Buy Me a Coffee's platform, which has its own privacy policy. No data is shared with Buy Me a Coffee simply by visiting this site.
No Analytics
We do not use Google Analytics, Plausible, Mixpanel, Hotjar or any other analytics or tracking service.
No Advertising
We do not display ads and do not work with any advertising networks. No advertising cookies or tracking pixels are present on this site.
6. Hosting & Infrastructure
This site is served as a static website via a web hosting provider. Standard web server logs (such as IP address and requested URL) may be recorded by the hosting infrastructure for security and reliability purposes. These logs are not used for marketing, are not shared with third parties, and are retained only as required for server security.
7. Children's Privacy
JSON Parser Online is a developer tool not directed at children. We do not knowingly collect any information from anyone under the age of 13.
8. Your Rights
Because we collect no personal data, there is nothing stored about you to access, correct or delete. If you have any privacy concerns, contact us at support@onlinejsonparser.com and we will respond promptly.
9. Changes to This Policy
If this privacy policy changes, the updated version will be published on this page with a revised "Last updated" date at the top. We encourage you to review this page periodically.
