Lumosity and memory

So, I’ve signed up to Lumosity , a brain-training regimen. There’s a website and an iPhone app. They encourage daily workouts, and there seems to be some science there as well. I got into it because I’m realising my memory, especially regarding names, isn’t that crash hot.

They’ve been hassling me, both in the app and via email, to sign up to reminder alerts, to remind me to do the exercises. Do they send this to everyone, or are they just targeting me because I told them I’ve got a crap memory?
