License
One-off, not a subscription.
You buy a personal license that lets you use Celestium on up to three of your own devices. The license is for one user.
Updates
Maintenance and improvements included.
Your purchase includes an update and support period of at least two years from your purchase date. During that period you receive maintenance, bug fixes and improvements within the version you bought. New functionality is not part of your purchase: if a major new version with new capabilities appears after that period, that is a separate purchase.
In practice: if something does not work properly during that period, it gets fixed. Improvements to existing features are included.
Before you buy
Good to know.
I use free chart software now. What do I get here on top of that?
Celestium brings calculating, storing, comparing, researching and learning together in one working environment. Your charts and data stay local on your own computer, and you can keep using the same environment as your astrological knowledge and way of working develop.
What if I do not get on with it?
That is why you can try Celestium for fourteen days first. You use the complete program, with every feature, without entering payment details up front. If you decide not to continue, you do not need to do anything.
Am I dependent on a subscription or a server?
Celestium is not a subscription service and runs locally on your own computer. You do not need the internet for your calculations and your saved charts. You only need a connection to activate your license, to fetch an upgrade, to deactivate a computer, and for the OpenStreetMap map in Astrocartography and Local Space. After that, Celestium tries to contact our server now and then to renew your license; if that fails, the program keeps working. The license terms explain what that involves under "Devices and activation".
Can I take my charts with me if I stop?
Yes. Your charts stay stored locally on your computer. You can also export data to supported formats, so you can use it outside Celestium as well. Other astrology programs and ordinary spreadsheets read those formats. Your data also sits in a file in your own documents folder, which you can copy and take with you.
