Can't stay within own country unless you pay - Don't waste your money, use a competitor
EDIT: The response that I got to this was an obvious misrepresentation. Their exact response was "Free accounts show matches globally, but upgrading allows you to set specific countries. Most dating apps also require paid plans for similar features" which is at best half true. The vast majority of apps allow you to see people close to you by default and charge if you want global settings, like a passport mode. If going to reply at least accurately represent your statement.
