Questions re getting started before signing up to plan

Hi all

As a newbie here and to websites in general I have a few questions. I am using the 14 day trial and have been given a URL by Squarespace and can see you get a free domain when you sign up to a plan. Do you get a choice over what this name is or is it just the random one they give you on the trial - or do I need to register it elsewhere first?

I plan to use the site for ecommerce I currently sell on Etsy but do all my listing from my phone. Adding products from a laptop is not practical because the photos are on my phone. I am aware there is an app could i add products from there or at least the photos of the products? Otherwise I have to download them from google photos on the laptop then upload them. I sell vintage so its not the same repeating product its quite a large inventory. Thanks!

You can change built-in domain ***.squarespace.com to anything. Home > Settings > Domain > Built-in Domain > Rename your built-in domain.

When you upgrade, you can choose a domain what you like. As long as the domain name has not been registered by anyone.

I haven't used SS from phone, but I think SS have an app to do this. You try contacting SS Customer Care.
