Narrative:

Departed from north buffalo suburban airport, ny for niagara falls, ny. After contact with buffalo approach control, they advised me 'contact niagara tower.' after contacting niagara tower they gave me what I understood was the following clearance: 'north cleared straight in runway 24 3 mi final,' I proceeded inbound and landed whereupon the tower called me on rollout saying 'do you know you landed without clearance?' I replied stating apologies but confused as to what happened. I usually repeat a clearance back and to my recollection, did so. If I misunderstood a clearance the controller did not correct me on readback. There was no further mention about the incident other than mentioned above.
