Why the need for PII? – TripIt: Travel Planner Review

TripIt now requires personal identifiable information, eg date of birth, to now use the iOS app. Why?? The terms and conditions state it optional to provide that information, so TripIt and it’s company, Concur, can’t even follow their own published terms. Lastly, I can log onto the website and there’s no requirement to provide DOB or other PII. For reference I’ve used TripIt for over 10 years, and have been at the Pro level all that time and my date of birth and other PII have never been required - just credit card info and email. Apple, you claim claim privacy is a right, well this needs to be addressed for the TripIt app.
