These days I treat other people's data like it's a live hand grenade. Case in point (bit of a shameless plug here :) I'm working on an App called Hockeytastic. It's an ice-hockey stickhandling app that my son's been using for months: the engine is solid but it looked like shit. However, his coach told me to get it on the app stores and sell subs. That meant I needed to clean it up, build a DB, store stuff etc.

Anyway, working with Google and Apple I realised that I quite literally do not need to store anything identifiable. The only identifier I store is the Apple id and the Google id and unless you steal those and then hack Google and Apple, they are utterly useless.

I do not store emails, names, addresses, nothing. That's the way I want it.

If the data is ever breached, the only thing hackers will see are many many instances of Connor McDavid, Nate Mckinnon and various other famous NHL player names :)

If more companies treated personal data like it was toxic, we'd have less issues with breaches, however, I see it in my day job where the marketing people want to take as much data as possible, all the time!
