A few times there's been a big media stories in the UK about a child who got badly abused or killed in domestic situations and then afterwards it turns out that various people (social services, teachers, charities etc) had concerns about the child's safety but concerns weren't written down or joined together and so the child could have been saved/rescued but wasn't.
So now in the UK we have a system of 'safeguarding referrals' where if someone has concerns they must make a safeguarding referral to social services but social services are terribly underfunded so the safeguarding referrals tend to pile up or just get filed unless they are really urgent. So now we have the problem of someone somewhere being responsible for wading through all the information and then identifying when the various reports from various places add up to a serious situation.
Hence you get an app like this where info from various agencies can be gathered in one place. https://www.bristol.gov.uk/residents/social-care-and-health/...
If you're going to hold government services such as social services or teachers responsible for childrens safety then this sort of thing is needed. And if you think thats not the job of the state then fair enough thats your opinion but in the UK the status quo is that it is the job of the state to look after vulnerable children/people.
