Will I lose my progress at fortnite if I delete it?

I have a fortnite acc and use it on the switch and on the ps4 but i would love to disconnect from the ps4 at epic games. If I do that I'll lose him? Because I got on it, the wlet I lose the game then synonymous?

In my opinion, the game is account-bound and not fixed to the console.

There should be no problems.

OK thank you
