Clash of Clans Connection

I connected my Clash of clans account with Google Play when I was at town hall 7. It somehow got disconnected from Google play (it shows a red button saying "Disconnected") and now I am at Town Hall 8. What will happen if I reinstall the game without connecting it again? will it start from town hall 7 or town Hall 8?

In simple words, do I need to connect it every time it gets disconnected to sync my progress or does it get synced and only one time a connection is needed?

Deleting an app on Android and iOS deletes all app data. If you were not connected to Google Play or Game Center, your data was not synced to the cloud. If you reinstall your game, you will start over with the last cloud save.
