Will I lose any remaining credit on my (trial) subscription if I buy an extension?
Do you already have an active (trial) subscription to the Nautical Maps app and want to buy a new subscription or extend it? Then we automatically add your new credit at the end of your current term. That means you can renew or extend your subscription at any time without having to worry about any existing credit.
You can see your current subscription credit at the top of your profile screen (access by tapping the symbol in the right-hand corner of the menu bar).
