Terms and licence

These terms are between you and Darren, trading as Lumenight, in the United Kingdom. Write to lumenight@mail.grokbot.com. They are written in plain English. They do not limit any right that cannot be limited.

The product

Lumenight makes a star chart for a date, time, and place you choose, and lets you download poster files. The chart is a keepsake. It is not for navigation, surveying, or anything where a wrong position could cause harm. Positions are geometric calculations for sea level. They are accurate to a small fraction of a degree on the sky, which is less than the width of a star dot on the print.

What you may do with your files

When you buy a key, you may print the maps you unlock, give them as gifts, and keep the files for yourself. You may not resell the files as a stock product, and you may not offer the maker itself as your own service. The words you type are yours.

Single and unlimited

A single map unlocks every format for one night (the date, time, and place). You can change the words and download that night again on the same device. Unlimited unlocks every night. The key is remembered in this browser. It is not an account we host.

Price and payment

Prices are in pounds sterling and are shown before you pay: £3.99 for a single map and £6.99 for unlimited. Payment is taken by Gumroad. Digital files are available as soon as the key is accepted, so please only buy when you are ready to receive them. That request for immediate supply can affect the automatic 14-day cancellation right. It does not affect your rights if the files are faulty or not as described. See the refund policy.

The data in the map

Star positions are adapted from the HYG Database under CC BY-SA 4.0. Towns are from GeoNames under CC BY 4.0. Details and links are on the credits page. Those licences apply to the data files, which stay separate from the rest of the site.

Law

These terms are governed by the law of England and Wales. If you are a consumer in the UK, you also have the rights given by the Consumer Rights Act 2015.
