Can I use identity Safe on my mac in the UK

I am in the UK.

 

I have norton identity safe on my PC. 

Can I access all my passwords and cards etc via identity safe when I go on to my imac computer?

If yes do how do I download the identity safe app? It wont let me download through it on the UK Apple app store and says I can get it on the US app store.

Or is there another way i can access all my passwords etc on my mac using Identity Safe?

 

Thanks
