FAQ

Can members freeze memberships for travel?

Yes. Freeze windows pause billing and access for approved date ranges without deleting the member record.

What happens at check-in if dues are past due?

Delinquent memberships can show a hold at the desk so staff resolve payment before granting access.

Do class packs share capacity with unlimited members?

Class sessions enforce a single capacity limit regardless of plan type; packs decrement credits on booking.

Can trainers see only their class rosters?

Trainer roles can be limited to sessions they instruct while owners see club-wide attendance and revenue.
