Add-ons for Better Notifications for WP (BNFW) are licensed for one year at a time. Since 9th June 2016, license renewals are automatic, unless cancelled, and allow you to receive updates and Priority Support without interruption.
No, the built-in automatic update system will take care of all of that for you.
Yes it will, and this is perfectly legal.
Yes. Renewing early will extend your license from its previous end. Renewing late will give you one more year beginning from your point of renewal.
Early renewal example: If you purchased in August 2015, and renewed in June 2016 your license would expire in August 2017.
Late renewal example: If you purchased in June 2015, and renewed in August 2016 your license would expire in August 2017.
No, not at this time.
No, you only need to activate your license on your Live site. You may still install your add-ons on your Test server and use it without an active license as an active license is only required for continued updates and support. You may however, find it beneficial to purchase a 2-5 site or unlimited site license (depending on your circumstances) in order to enable updates on all servers that you use during production. If you wish to change the URL currently in use on a license, you can do so from Your Account.
If you purchased an add-on after 9th June 2016 then it is set to renew automatically. If you purchased an add-on before that date then you’ll need to renew manually. Once you manually renew it will be set to automatically renew from that point onward.
You will receive an email notifying you of the renewal.
You can log into Your Account and end your subscription at any time. This will NOT remove any subscription time / support / licenses you’ve already paid for, it will merely make it so you don’t automatically renew when your subscription time ends.
