The license allows: modifying the sources and creating derivative works, linking with or embedding into proprietary software, re-branding and removing attributions to TightVNC, distributing in the compiled binary form. The license does not allow: re-licensing the source code to a third party, distributing the source code.

Currently, we offer two payment plans, where the second one increases the total cost by $500 but allow payments in parts. Here is the list of payment plans available: 1. One-time payment: $12, Payment in two parts: $6,500 initial payment + $6,000 one year later. Here is an example illustrating these payment plans assuming the initial payment date was set to July 15, 2012: Payment Plan July 15, 2012 July 15, (one-time) $12,000 (perpetual license) 2 (two parts) $6,500 (license expires on July 15, 2013) $6,000 (perpetual license) As seen from the table above, the license goes perpetual once all payments have been completed. For plan 2, a limited-time license will be granted on the initial payment, with its expiration date set to the next payment date. For this plan, it's possible to obtain a perpetual license at any moment by issuing a payment for the remaining amount. To make sure the price will not increase, place your order today! 2
