I track a few actions in the app to help me understand usage and make improvements:
When you use iMessage's sticker pack, there is no tracking. I don't receive any information about when or how you use it.
You can get in touch and receive replies in the app anonymously. You never have to provide your personal information to get support. If you do choose to share your info, I'll store that. Tracked events will be linked to you if you do.
Any information you provide to me will not be sold or shared. I won't send you marketing messages of my own either. If I am legally required to share information with authorities, I will do so.
You can request access to and/or deletion of data I hold about you. Just get in touch via the messenger and I'll be happy to arrange that for you.
