FAQ
Does obfuscated code still run?
Yes. Obfuscation changes readability (names, string encoding, control flow) without changing behavior; verify in a test environment after obfuscating.
Can obfuscation prevent cracking?
It greatly raises reverse-engineering cost but is not absolute; combine core algorithms with server-side checks.
Is my code uploaded?
No, obfuscation runs entirely in your browser.
