Using Fitbit attributes in iOS apps

[Credelius]

@JonFitbit et al. Quick qs about using Fitbit's attributes on 3rd parties platforms. I've created an app for iOS platform, similar to Android's one: a user can create 2FA accounts on iPhone, transfer to Fitbit, backup/restore, etc. Appstore folks saying that I might need a permission from Fitbit to mention Fitbit in the app description. A few qs about this:

1. If this is correct, is there anyone on Fitbit's side to talk to?

2. Is it OK to show a Fitbit's icon in the iPhone's app when a Fitbit device is connected (see the picture below). I can replace it of cause with something more generic, but user experience will suffer, since I plan to add more types of smartwatches.

@JonFitbit - thanks for the quick answer. I've checked the icons and they do not fit very well my design profile. I need a circle shape with alpha, while what is suggested is a square with a white opaque background.

Is it OK to edit them to meet my criteria or I can only use them as is ?
