Tracking on iOS 14.5+
If you are using Twitter for iOS 14.5 and up, Twitter is required to request permission to track data on your device from other companies, like apps you use and websites you visit.
For each iOS 14.5 and up device that you use Twitter on, you will see a prompt from Twitter providing information about Twitter’s tracking, followed by a tracking prompt from your iOS device for the Twitter app.
How can I control Twitter’s tracking on my iOS 14.5+ device?
If you allow tracking through the prompting process described above, Twitter will engage in tracking on the device that you granted the permission to track as described in our App Privacy section. If you choose not to allow tracking, Twitter will not engage in tracking on that device.
These choices only affect how Twitter may or may not track data on the applicable device going forward, after you have responded to Twitter’s iOS 14.5+ tracking prompt. Your choice may not go into effect immediately.
Regardless of whether you allowed or declined Twitter permission to track you through the prompts described above, you can always go to your iOS device settings and select Twitter to adjust whether to allow tracking.
