IonianCore Proprietary License (Closed Source)

[cite_start]Important Notice: All IonianCore applications, games, and web tools (including the "IonianCore Engine" logic, UI/UX designs, and custom scripts) are Closed Source Proprietary Software[cite: 1, 8].

The source code is strictly confidential and is not available for redistribution, modification, or public viewing. While our applications run in the browser for security, the underlying logic remains the intellectual property of IonianCore.

  • No Reverse Engineering: It is expressly prohibited to decompile, disassemble, or attempt to derive the source code of any IonianCore Web Application or Game.
  • No Redistribution: You may not copy, sell, or host our tools on third-party servers without written consent.
  • Usage Rights: You are granted a license to use the tools for personal and commercial purposes (e.g., creating PDFs, generating QR codes), but you do not own the software itself.

The Zero-Knowledge Architecture

At IonianCore, we believe that your data belongs to you. This is why we have engineered a Zero-Knowledge Architecture that distinguishes us from the competition. Unlike traditional online converters that upload your files to a remote cloud server—creating potential privacy risks—our tools operate 100% Client-Side.

This means that when you use our Merge PDF tool or our Images to PDF Converter, the data processing happens physically within your device's memory (RAM) using WebAssembly (Wasm) and advanced JavaScript modules. Your financial documents, legal contracts, and personal photos never leave your browser environment.
