Does Uber disclose their data retention policies? I don't see any need for them to retain my trip history on a non-anonymized basis, other than a short lookback

Does Uber disclose their data retention policies? I don't see any need for them to retain my trip history on a non-anonymized basis, other than a short lookback period for driver and date/time for purposes of finding lost items. And I would feel better knowing that they publicly state as much.
