It scans your data to send you notifications. I got an email once thru the Win10 Mail app on my computer and I responded saying that "I'll send doc x in the morning" and the next morning when I woke up and looked at my phone - this launcher app had a notification, "don't forget to send doc x" and had the email recepients name. Again, I did all this on my computer but the launcher is syncd and will send you notifications based off what you type in any MS Office app.
