How Do I Manage My Subscription?
Your subscription is managed by the service you subscribed to, i. e. Paddle, App Store or Setapp. You may access your account from within the app or go to your service's account and manage the subscription there.
Open the application preferences and switch to the subscription tab. After clicking on Manage Subscription, you may
- Extend Subscription - You may add additional licenses to your subscription, so that it can be used on more then 2 devices.
- Cancel Subscription - The app can be used until the end of the subscribed period and will expire thereafter. Your data will remain available without subscription and the software can be used in "read only mode".
- Payment Information - You may adjust your credit card or PayPal details for the next payment.
