Commonly Asked Licensing/Subscription Questions
One subscription price ($12 per year) activates Trillian Pro on your account across all computers and mobile devices, regardless of version. Lifetime subscriptions are available, which exempt you from ever having to renew a subscription. If you've ever purchased Trillian Pro (any version) you're eligible for a customer loyalty discount on lifetime licenses.
Customers who received a Trillian 5 Pro pre-order with their Trillian Pro 4.x purchase (during the period that Trillian 5 was still in beta) have a 'grandfathered' license for the entire Trillian Pro 5.x series. This means you're exempt from subscription expiration on Trillian 5.x and can upgrade to Trillian 5.1 for free!
When you sign in to the Trillian Store here you'll be shown offers that are applicable to your account. For example, you won't be offered an annual subscription right now if you purchased during Trillian 5 Pro pre-order period (You're 'grandfathered' into 5.x), or you won't be offered lifetime if you've already purchased lifetime.
