You trust us to be careful with your data, and because of that, we want to be open with you when we make a mistake. We have discovered that we were inadvertently collecting and sharing iOS location data with one of our trusted partners in certain circumstances.

Specifically, if you used more than one account on Twitter for iOS and opted into using the precise location feature in one account, we may have accidentally collected location data when you were using any other account(s) on that same device for which you had not turned on the precise location feature.
