Thank you for deciding to renew your license. Your contribution enables me to support and grow the Add-on further and keep in sync with the ever changing Thunderbird platform. The renewal has a 33% discount versus a new license.

Annual License / Premium Features

The license is valid for 1 year from date of purchase or from expiry of the license, whichever is longer. It does not renew automatically.

QuickFolders Pro gives you full unrestricted access to its premium features. It also turns off the donation pages which are displayed on update with the free version of QuickFolders. More premium features can be added during that time, and there may be "premium exclusive" features not visible to free users.

Personal License Key bound to Email Address

The license is for your personal use and is tied to your email address. The email address must be defined as default identity in any one of your Thunderbird accounts. The validation of the email runs offline and the address is not stored on any server nor transmitted during use. With this mechanism, you can have additional email addresses, which do not need a separate key. You can install and use it on multiple email clients as long as they also have the primary address.

Updates

QuickFolders Pro will be automatically updated via addons.thunderbird.net as usual. After the license term expires you can renew the license or keep using premium features under same restrictions as free users. "Premium Exclusive" features will require a valid registration key.
