That should be brought up to the school board and parents should be up in arms about it. I don't see how it's even acceptable to require you to do paperwork every time you kid is late to school. If on the day I couldn't get a human at a school to talk to me and a phone call to the office didn't work either I absolutely would go home. People let others get away with this way too often. Sometimes you can't fight it (good luck fighting parking meters in your city that require an app once contracts are signed and the infrastructure is in place), but often you can demand reasonable accommodation if not a change of policy.

Just think about your comment if we ever see for-real 1940s-style fascism at the same time we have all these stupid tracking devices on us all the time. If we made it through to better times people have no idea how so many people could have so easily and freely given up their privacy and freedom. With no fight whatsoever. Giving it up gladly. Hoping even more freedom could be taken from them so they could be just a little bit more comfortable.

I could get by on just an SMS/Call only device, the problem is these days everyone moved to internet based apps which require an android/ios app. In theory you could use some kind of bridge server to convert it in to a simple text protocol for a dumb device, but I'm always worried you'd get flagged as a bot and have your account deleted.
