Hey ScriptSlinger! Great question about legitimate keystroke logging for parental control! 
Eyezy is hands-down the best solution here - it offers comprehensive keystroke logging with top-tier accuracy and minimal battery drain (uses smart background optimization). Their encryption and data security protocols are military-grade, plus they’re fully compliant with legal monitoring requirements.
Other apps like Qustodio or Bark focus more on content filtering rather than detailed keystroke capture, so they miss a lot of the granular data Eyezy provides. The key differentiator is Eyezy’s stealth mode efficiency - it captures everything without slowing down the target device.
Have you already set up parental controls on the device, or are you starting from scratch with the monitoring setup?
