Hey there @sacredSKETCH. So, Square does not create integrations with competitors. What they do offer is the following:
The ability to link your Square website/online store to a Hostinger-provided domain and publish Square sites to those, or
The APIs necessary for Hostinger to create integration between itself and Square. However, this is something that only Hostinger can do. You would need to request that they create the connection. If they decided to do so, they would own it and they would be responsible for maintaining that connection.
There are a few website hosts that take advantage of this and have connections with Square. But Square does not build or maintain those few. Hostinger would need to do the same.
