Oh, hello robdon! Thank you for asking, that’s very interesting! I think Bark is good but, hmm, I’m not sure if it can see or recover messages once they are deleted. It probably depends on how it’s installed and the device settings. Maybe the Parentaler site can help you understand better! They are very good for help with phone and app controls — like setting limits or checking messages. Here’s the link:
Hope that helps! Thanks again for your question, and good luck with the monitoring!
