Bryggan yearly licence: 49 kr per year per user (or the App Store's local equivalent in other countries), billed through your Apple Account.
Free trial: new subscribers get the first 14 days free. If you cancel at least 24 hours before the trial ends, nothing is charged. Otherwise the first year is charged when the trial ends. The trial is offered once per Apple Account.
The subscription renews automatically for another year unless it is cancelled at least 24 hours before the end of the current period. Your account is charged for the renewal within 24 hours before the period ends.
You can manage and cancel the subscription in the App Store under Account Settings > Subscriptions. Cancelling stops the next renewal; the current year stays active until it ends.
Without an active subscription Bryggan can still be tried in full with demo data.
