Privacy Policy

Your privacy and data security are the foundational principles of JSON Empire. Read how we handle client-side data, analytics, and advertising compliance.

📅 Last Updated: August 16, 2026 • 🔒 100% Client-Side Air-Gapped Architecture

🛡️ The JSON Empire Zero-Data Guarantee

We do NOT store, transmit, log, or inspect your JSON data. All data transformations, schema validations, code generation algorithms, formatting, and file conversions occur 100% locally inside your browser runtime. No JSON payload entered into our tools ever leaves your device.

1. Introduction & Overview

JSON Empire ("we", "our", or "us") operates the website located at https://jsonempire.com/ (the "Service"). This Privacy Policy explains our practices regarding the collection, use, and disclosure of personal data when you visit our website, as well as the choices you have associated with that data.

By using JSON Empire, you agree to the collection and use of information in accordance with this policy. If you do not agree with this policy, please do not use our services.

2. 100% Client-Side Data Processing

Unlike conventional web utilities that transmit your proprietary payload to remote servers for server-side processing, JSON Empire utilizes modern client-side JavaScript (V8 Engine, Web Workers, and Web Assembly). When you paste JSON, XML, YAML, CSV, Protobuf, or any other data format into our tools:

  • The data is processed solely in your device's local Random Access Memory (RAM).
  • Zero HTTP POST, PUT, or GET requests containing your payload are sent to our backend servers.
  • When you close or refresh the browser tab, your data is completely discarded from volatile browser memory.
  • Your API keys, JWT authorization headers, medical records, financial payloads, and confidential customer databases remain completely secure and air-gapped on your computer.

3. Google AdSense & Third-Party Advertising

To maintain JSON Empire as a 100% free suite of developer utilities, we monetize our platform using third-party advertising services, primarily Google AdSense.

Please review the following essential disclosures regarding Google AdSense:

  • Third-Party Cookies: Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to our website or other websites on the Internet.
  • Advertising Cookies (DART Cookie): Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visit to JSON Empire and/or other sites on the Internet.
  • Personalized Advertising Opt-Out: Users may opt out of personalized advertising by visiting Google's Google Ad Settings.
  • Industry Opt-Out Portals: Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting the Digital Advertising Alliance (DAA) Consumer Choice Page or the Network Advertising Initiative (NAI) Opt-Out Page.

4. Cookies & Local Browser Storage

Cookies are small files placed on your device. We and our third-party service providers use cookies and similar technologies (such as HTML5 LocalStorage) for the following purposes:

  • Essential Preferences (LocalStorage): We store your preferred theme setting (json_empire_theme: "dark" | "light") in your browser's LocalStorage to maintain a seamless user experience across pages. This contains zero personally identifiable information (PII).
  • Advertising Cookies: Used by Google AdSense to serve relevant ads, limit ad frequency, and measure ad effectiveness.
  • Analytics & Performance: Used to understand site traffic trends and identify performance bottlenecks across our 50 developer tools.

5. Server Log Files

Like most standard web hosting environments, our hosting infrastructure automatically logs standard web request details. These log files may include:

  • Internet Protocol (IP) addresses (anonymized where required by law)
  • Browser type, operating system, and device category
  • Internet Service Provider (ISP)
  • Referring and exit pages, date/time stamps, and pages visited

Log data is used exclusively to administer the site, prevent denial-of-service (DDoS) attacks, ensure network security, and diagnose server latency. Log data is never linked to individual user payloads.

6. User Feedback & Communication Data

When you choose to submit a tool request, bug report, or feature suggestion through our Community Feedback Form:

  • We collect the information you voluntarily provide (Category, Title, Description, Your Name, and Optional Email).
  • This data is stored securely in our Firebase Firestore database to enable our engineering team to review and resolve developer requests.
  • We will never sell, rent, or lease your email address or feedback information to third-party marketers.

7. GDPR Compliance (European Economic Area)

If you are a resident of the European Economic Area (EEA), you have specific data protection rights under the General Data Protection Regulation (GDPR). JSON Empire aims to take reasonable steps to allow you to correct, amend, delete, or limit the use of your Personal Data:

  • Right of Access: You have the right to request copies of your personal data.
  • Right to Rectification: You have the right to request that we correct any information you believe is inaccurate.
  • Right to Erasure: You have the right to request that we erase your personal data under certain conditions.
  • Right to Restrict Processing: You have the right to request that we restrict the processing of your personal data.
  • Right to Data Portability: You have the right to request that we transfer the data we have collected to another organization.

To exercise any of these rights, please contact us via our Contact Page.

8. CCPA / CPRA Privacy Rights (California Residents)

Under the California Consumer Privacy Act (CCPA) and the California Privacy Rights Act (CPRA), California residents are entitled to:

  • Know what personal information is being collected about them.
  • Know whether their personal information is sold or disclosed and to whom.
  • Say "No" to the sale of personal information (JSON Empire does NOT sell personal data).
  • Access their personal information and request its deletion.
  • Receive equal service and price, even if they exercise their privacy rights.

9. Children's Online Privacy (COPPA)

JSON Empire is a professional developer utility suite and does not knowingly collect or solicit personal information from children under the age of 13. If you believe that a child under 13 has provided personal data to us, please contact us immediately, and we will promptly delete such information.

10. Changes to This Privacy Policy

We may update our Privacy Policy periodically to reflect changes in our legal obligations, third-party advertising requirements, or platform capabilities. We will post the revised version on this page with an updated "Last Updated" date.
