Is teamspeak3 server licences permanent?

This might be a dumb question, but is teamspeak3 gamer license permanent? Cause I didn’t see a monthly price on above it.

If you look here:
Pricing | TeamSpeak

It does say Annual Renewal Cost (USD$)

But that depends on the license you take. Remember there is a free license for free (up to 32 slots)

Oh okey, Thanks
