Seems like this AphyOS is de-googled android, not sure if they use MicroG but apart from FAQ there's no mention of 'Android'.
Being android the trade off between convinience and privacy might be lesser than a purpose built Linux Phone like Librem. Their marketing copy suggests it's not for the same audience as say Librem or Graphene OS phone.
Ofcourse many of their advertised privacy features can be achieved for cheap with any LineageOS/postmarket OS phone with self-hosted Nextcloud.
