Part 107 UAS pilot reported flying in controlled airspace without authorization.

Narrative

I was preparing for a short flight to document a roofing project for a building recently completed. I went through my standard preflight procedure of checking my Aloft Air Control Application for airspace information and to request LAANC clearance if required; but I misinterpreted the language in the application. The app confirmed that the area was within the UAS Facility Maps and had automatic approval up to 400'. My misinterpretation resulted in me thinking that this was a class G airspace and did not require LAANC approval. Upon launch I gained ~100 feet of altitude before I noticed a notification alerting me I was in a Class D air space. Upon viewing that notification I landed the UAS and did not resume flight.I believe the primary cause for this event was my misinterpretation of the text within my Mobile application and my rushed execution due to time constraints. A minor cause for this event is the text within my drone's app; as I trusted the text that indicated 'Takeoff permitted'. I understand that in the future more time should be reserved for ensuring that all LAANC approvals are properly received if I am intending to fly within a restricted air space that is part of the UAS facility map.
