    On PC (via Emulator):

    Safety & Legitimacy Checks

    Since Castle is a third-party APK, it’s important to make sure you download safely.
    Use Only Official Sources: The “Castle Premium” or “Mod APK” type sites can be pretty fishy, I wouldn’t trust them, they could always have malware hidden.
    For Castle lite permissions, it'd require your network and storage; don't give access to contacts or messages, true to you.
    Scan First: If you’re not sure go ahead and scan it with a malware scanner.
    Back Up Before You Reload: If Castle saves your watch history, or downloads movies to your computer, back them up before you reinstall.
