The plugin will remain working for the grace period and then it will stop working. So if you subscribe to the monthly plan on the 1st and you cancel it on the 15th you will be able to use it for 15 more days. Then it won't work and will show you a warning asking to reactivate your plan.
What is a local database for geolocation ?
Some users, because they don't need much accuracy, or because their sites have so much traffic that can't rely on third party APIs, prefer to use instead a local solution.
That's why we made all our plugins compatible with other geolocation services, letting our users install their databases locally to empower our WordPress geolocation plugins.
What databases are compatible ?
You can use the city free Maxmind Geolite2 database or the city Maxmind GeoIP2 database, IP2Location databases, Kinsta Geoip and also Wp Engine GeoIp services data.
Check on local database docs page for install instructions.
