Each new purchase of SeeYou includes the base license and 12 months of upgrades and updates.
SeeYou uses subscription upgrades to maintain the latest version after the first 12 months. A SeeYou subscription upgrade includes a yearly subscription for 49 EUR (+VAT if applicable). Like before the SeeYou license is still perpetual which means that if you cancel the subscription you can keep using the old version of SeeYou without limitation and with the data that was present on your PC at the time your subscription expires. You just can’t upgrade to the newer version without buying another upgrade.
If your subscription has lapsed and you would like to upgrade, simply purchase a subscription upgrade and this will give you the latest version of SeeYou and 12 months of upgrades and updates.
