Your score tells you where to stand.
Even score: the player who started on the right is on the right. Odd: they're on the left.

Why
You only swap when your team wins a point on its own serve. One point, one swap. Odd points, off your starting side.
The receiving team never moves.
The pocket version
Even: starter on the right.
Odd: starter on the left.
Each team, its own score.
