When making a purchase on Daan.dev, a subscription is created for you, which automatically renews your license.
If you wish to not (automatically) renew your license, you can easily cancel your subscription by navigating to the Subscriptions screen in your account area and click Cancel next to the corresponding subscription.
I changed my mind. Can I reactivate my subscription?
Yes, but not from the Subscriptions screen.
To reactivate the subscription for your license, you need to manually renew or extend it from the Licenses screen in your account area.
