Privacy Policy

1. Introduction

JSON/CSV Converter ("we", "us", or "our") operates the conversion tool. This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our service.

2. Data Processing Approach

100% Client-Side Processing: All data conversion operations occur exclusively in your web browser. No files, data, or personal information are uploaded to our servers. Your data never leaves your device unless you explicitly choose to download or share it.

3. Information Collection & Use

We design the Converter to avoid collecting personal data wherever possible. By default, the converter:

• Does not require user registration or login
• Does not upload your JSON/CSV file contents to our servers
• Does not store conversion history on our servers

4. localStorage Usage

The tool uses browser localStorage exclusively for functional purposes:

• Conversion Templates: Stores your saved column configurations locally
• Conversion History: Keeps a log of your recent conversions (max 50 entries)

This data is stored only in your browser and can be cleared anytime by clearing your browser cache.

5. No Third-Party Data Sharing

We do not share, sell, or transfer any data to third parties. Since we don't collect data, there is nothing to share.

6. Analytics & Advertising

In some deployments we may enable privacy-conscious analytics (for example, Google Analytics or Cloudflare Web Analytics) and advertising via Google AdSense to keep the service sustainable. When these services are active, they may set their own cookies or use similar technologies to measure usage and deliver ads.

• Analytics data is used only in aggregate to understand feature usage and improve reliability. We do not sell analytics data or combine it with conversion contents.
• Google AdSense and related Google services may use cookies or identifiers to show relevant ads and prevent fraud. For details, see Google's advertising policies.

6. Security

Your data security is paramount:

• All connections use HTTPS encryption
• No data is transmitted to external servers
• Browser localStorage is restricted to your device

7. GDPR Compliance

Since we collect no personal data, GDPR regulations regarding personal data do not directly apply to our service. However, we respect your data rights:

• You have full control over all data in your browser
• No data is stored on our servers to delete or access
• You can clear localStorage anytime

8. Children's Privacy

Our service is not directed to anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13.

9. 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.
