The versions of Sector Planner for X2 and X3 have probably taken somewhere in the region of 1,000 hours of my own time to develop and maintain which I have given freely to the community.  Sector Planner is free to use and will always remain so, however if you wish to express your thanks, donations are truly appreciated, however big or small.

Donations are handled via PayPal, however you do not need to be a PayPal member to donate and you can even pay directly via Credit Card. 
I promise that I will put your personal details to no use, other than to thank you for your donation and include your name (or nick) on the credits section of Sector Planner.

Please feel free to request a feature when donating and although I can't guarantee I will add a feature, I will prioritise those from people who have made a donation.

In the near future I intend to add some functionality to X3: Sector Planner that will only be available to those people who have donated to give those who have supported me something back.
