Yes, it is. When you purchase an activeCollab license you can use it for as long as you want - there is no time limit on its usage.
As well as a license to use activeCollab indefinitely, each purchase also includes one year of free Support and Upgrade Subscription.
If you wish to have access to new upgrades and official activeCollab support after the first year expires you will need to renew your Support and Upgrade Subscription. Renewal is optional and it is completely up to you to decide whether or not you wish to purchase this extension. Either way, you will be able to use your copy of activeCollab for as long as you want.
