There are a lot of apps that run in the background in order to make the ones you click on work (though 2 of these actually are the things you click on). This is true of any phone, and indeed any computer. The reason you've not seen these before is probably because you haven't looked before.
I did do a little checking on "
Bark". It seems to be a "parental monitor" service, which you pay a subscription to use. A couple of excerpts from their FAQs might be relevant to your post (emphasis added by me):
* What will my child think about Bark's monitoring features?
Kids are generally receptive to Bark once they learn that we protect them online while also giving them more privacy.
Parents don’t get access to every single message they send — only to online activities that indicate that they might be in danger. Here’s
how to talk to your child about Bark.
So they claim this can't give her access to every message you send or receive, just those that pass some filters.
* Will my child know that Bark is installed?
While it is technically possible to set up Bark without your child's knowledge (assuming you have the log-in information for their online accounts), we highly encourage you to discuss your usage of Bark with your child. Talking to your child about alerts when they arise provides a good opportunity to have important conversations about serious topics.
So a lot of monitoring is only possible if she knows your passwords.
Also the client on your phone doing the monitoring is called "Bark for kids". It doesn't sound like it is that well hidden.
I can't say that she doesn't have spyware on your phone, but this app doesn't sound like it would be a very good choice for that purpose.
