APK Shield is intended only for APK files you own or are explicitly authorized to modify. Do not use it to alter, redistribute, or bypass controls in third-party applications.

Please open a private GitHub security advisory for vulnerabilities that could expose signing credentials, execute unexpected local commands, or weaken payload integrity. Avoid attaching real keystores, passwords, proprietary APKs, or decoded application contents.

APK Shield raises the cost of casual static dex inspection. It is not a hardware-backed key management system, a substitute for server-side authorization, or complete protection against a determined reverse engineer. Both masked key components are necessarily present in the generated runtime. Flutter AOT code in libapp.so is outside the dex protection boundary.
