This is the code I wrote as part of https://cloud.sagemath.com in order to integrate IPython notebooks into my existing document synchronization infrastructure. It's CoffeeScript code that isn't meant to be run-able (I just copied it out of a bigger file). I just thought there could be some value in making this available under a BSD license, sin…

Grammarly iOS Keyboard — Unboxing

Grammarly iOS Keyboard – Unboxing

Grammarly is a lovely writing assistant. Twenty million people use the tool across the globe according to the statistics available on the site. I use it too. No complaints, it does its job quite well, and I am a happy user. The only thing that always worried me is the Grammarly iOS Keyboard. As an iOS engineer, I know how easily you can collect different data, sensitive information, and even do not ask users about the consent. So, let's check what is inside the Grammarly iOS application.

TL;DR

  • Grammarly iOS uses at least three trackers (Adjust, AppsFlyer, Internal analytics)
  • Grammarly Keyboard has access to keystrokes, sensitive data, and able to send them over the network
