Privacy Policy
Your data never leaves your browser. This applies to both the website and the Chrome extension.
Last updated: August 17, 2026
Summary
CSV to JSON Converter processes all data locally in your browser. No file content, no CSV data, and no JSON output is ever sent to any server. There is no analytics, no tracking, and no third-party code.
1. Data Processing
All CSV parsing, JSON conversion, nested mapping, and batch processing happen entirely within your browser using JavaScript. The extension uses the PapaParse library (bundled locally) and JSZip (bundled locally) to process files. No external servers are involved in data processing.
2. Data Storage
The extension stores only the following in chrome.storage.local:
- Conversion counter — number of free conversions used (integer)
- Unlock status — whether you've purchased unlimited access (boolean)
No file content, no file names, no CSV data, and no JSON output is stored. All file data is discarded from memory immediately after conversion.
3. No Tracking
The extension does not use Google Analytics, Google Tag Manager, Mixpanel, or any other analytics or tracking service. There are no tracking pixels, no cookies, and no fingerprinting.
4. No Third-Party Code
The extension does not load any remote scripts. All code (PapaParse, JSZip,
and application logic) is bundled locally within the extension package.
The Content Security Policy restricts execution to 'self' only.
5. Payment Verification
If you choose to purchase unlimited access ($5 lifetime), the extension sends your USDT transaction ID (TXID) to our Cloudflare Worker for verification. The Worker checks the transaction via the TronScan public API and returns a boolean result. Only the TXID string is transmitted — no file data.
The verified TXID is stored in Cloudflare KV for 30 days to prevent replay attacks. No personal information is collected or stored.
6. Permissions
The extension requests only the storage permission, which is used
to save the conversion counter and unlock status locally on your device.
No tabs, no host_permissions, no content scripts,
and no background service workers are used.
7. Website (csv-to-json.com)
The website operates on the same privacy principles. All file processing happens client-side. No file data is uploaded. Cloudflare Web Analytics (privacy-preserving, no cookies) may be used for aggregate traffic statistics.
