Privacy Policy & Security Model
Last Updated: August 2026
1. The 100% In-Browser Privacy Guarantee
At B64EncodeDecode (encoderbase64.com), your privacy and data security are our highest priorities. Unlike traditional converter websites that upload your data to remote backend servers, all text encoding, decoding, file processing, and image visualization happen 100% locally inside your web browser using native JavaScript Web APIs (TextEncoder, TextDecoder, FileReader, Blob) and Web Workers.
2. Zero Server Logs & Zero Data Storage
Because our application runs strictly on the client side, our servers never receive, inspect, log, or store any of the content you type, paste, or upload. Even if you process confidential API keys, sensitive tokens, private certificates, or personal photos, that data never leaves your device.
3. Local Storage Preferences
We use browser localStorage strictly to remember your visual theme preference (Dark Mode vs Light Mode). No user identifiers, cookies, or personal tracking beacons are created or shared with third parties.
4. Offline Capability
Once loaded into your browser, you can disconnect your internet connection and B64EncodeDecode will continue to encode and decode your files and text with full speed and functionality.
