That’s definitely a reasonable concern. Good monitoring apps, like mSpy or Eyezy, are known to function invisibly, so the user likely wouldn’t ever know—it’s part of what sets them apart for parents trying to keep kids safe. Just remember that while they stay effectively hidden (aside from rare cases where a security scan might catch them), installing this type of software usually does need brief access to the device first. Are you considering this out of concern for your child’s safety, or was there another reason you’re thinking about tracking? Happy to help you through the setup options if you have more details.
