Privacy Policy
Our Privacy-First Approach
✓ All file conversions happen directly in your browser
✓ Your files never leave your device
✓ No data is uploaded to our servers
FormatKit is built with privacy as the core principle. Unlike traditional online converters that upload your files to remote servers, FormatKit processes everything locally in your web browser using JavaScript. This means your sensitive documents, images, and data remain completely private and secure on your device.
Data Collection
We do not collect, store, or transmit any of the following:
- Files you upload or convert
 - File contents or metadata
 - Conversion history
 - Personal information
 - IP addresses
 - Device information
 
Cookies and Tracking
FormatKit does not use cookies, analytics, or any tracking technologies. We don't use Google Analytics, Facebook Pixel, or any third-party tracking services. Your browsing activity on FormatKit is completely private.
How Client-Side Processing Works
When you use FormatKit:
- You select a file from your device using the browser's file picker
 - The file is read directly by JavaScript running in your browser
 - Conversion happens using client-side libraries (no server communication)
 - The converted file is generated in your browser's memory
 - You download the result directly from your browser
 
At no point does your file data travel over the internet or touch our servers.
Transparency
FormatKit's code is transparent and can be inspected using your browser's developer tools. You can verify that no network requests are made when converting files (except for loading the initial application assets).
Third-Party Services
FormatKit is hosted on Vercel. While Vercel may collect standard web server logs (such as page views and basic access logs for infrastructure purposes), they do not have access to the content of files you process, as all conversion happens client-side.
Data Security
Since your files never leave your device, they are as secure as your local machine. We recommend:
- Using FormatKit on a secure, trusted device
 - Ensuring your browser is up-to-date for the latest security patches
 - Clearing your browser's cache if using a shared computer
 
Your Rights
Since we don't collect any personal data, there is no data to access, modify, or delete. You are in complete control of your files at all times.
Changes to This Policy
If we make any changes to this privacy policy, we will update this page. However, our core commitment to client-side processing and user privacy will not change.
