Cookie & Local Storage Policy
Last updated: September 2026 • Compliant with GDPR, ePrivacy, and CCPA/CPRA
🔒 Total Data Protection & Zero Third-Party Advertising Cookies
Unlike traditional online converters that upload your files to remote cloud servers, MediaConvertKit operates with strict local data protection via WebAssembly. Your files are processed with complete confidentiality and are never transmitted to our servers or any third-party tracking networks.
1. What Are Cookies and Local Storage?
Cookies and local browser storage (such as HTML5 localStorage and Cache Storage) are small pieces of data stored on your device by your web browser. They allow websites to remember your settings, keep your session active, and load essential application code faster on return visits.
