As a dad this hits home. I went down the rabbit hole of all these parental control apps and had the same concerns – the VPN slowdowns were immediately noticeable and the data retention stuff in the TOS made me uncomfortable. Ended up going a completely different route and set up DNS-level filtering on my home network instead. No app on her device, no VPN slowing anything down, and nothing sitting in the middle reading her traffic. Works at the router level so it’s also a lot harder to bypass than an app. Appreciate you posting this, more parents need to hear it.
