Terms and conditions
The usage of this site is completely free and is provided as-is, without guarantess of any type. It is maintained by individuals (i.e. not a company) during their spare time, so please tie your expectations to this fact.
Calculated values such as rise, transit and set times, and all celestial object positions depend on your location. They are approximate and provided just as rough estimates - they should be good enough for any kind of amateur astronomer activity.
Please plan your observing sessions ahead, as it may prove difficult to fix the site quickly if a problem arises.
The best effort is done to preserve all user generated data and keep e-mail reminders going out. In case of loss of data, we'll do the best to recover it but cannot guarantee it.
When registering your account, we'll susbcribe you automatically to a monthly reminder of popular objects tailored to your locations. You can unsubscribe right away from your personal settings page, or from a link in the first e-mail you get.
After creating your account you'll be able to choose the type of license you'd like to apply to images you share with the community on this site. This way you can rest assured nobody will use your images in a wrong way. All accounts will have a default license applied to their images, which is Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International. This means that nobody will be able to use your images in a commercial way without your previous authorization. If someone uses your pictures for any non-commercial purpose, they will need to give appropriate credit to the author (you). If you don't like this option, there are other license options available when editing your profile.
Besides the license you choose to share the pictures with the world, by uploading any image you authorize this site to reproduce it, as well as derivative versions (like inverted monochrome or annotated versions) for didactic, advertising or any other purpose other than selling your digital images directly.
This site is a donation-driven endeavor. Your donation helps covering the cost of running and maintaining this site. The more donations, the more time we can work on the site.
These terms and conditions may change, in which case we'll notify you by e-mail (in case you are registered) so you can stop using the site if you don't agree with them.
The usage of this site implies the acceptance of all the terms and conditions displayed in this page.
