About & support
Who makes ZenithBoard and this site, under which licences, with what respect for you, and how to say thank you.
Who
ZenithBoard and this site are made by Régis Hennequin, in Moselle, in the east of France, where the reference Raspberry Pi has been running outdoors since the first version. The code is public on GitHub, under the name regis57, and every release is tested on that Pi before it is published. The story behind the project is told on his own site.
The promise
The sky above you, decoded by you, shared with the world. Everything here serves that sentence: the receiver is yours, the data is in the open, and the maps exist because people share. Nothing is sold and nothing is collected.
The licences
ZenithBoard’s code is under the GNU General Public License, version 3 or later: you may use it, read it, change it and pass it on, under the same terms. The text of this site is under Creative Commons Attribution – ShareAlike 4.0: quote it, translate it, reuse it, with a mention of where it comes from and under the same licence. The site’s own code is under the GPL too, in its own public repository, so that anyone can check what it does.
Respect for people
The wall and the posts never give a receiver’s position away. No airline logo and no manufacturer logo is drawn, in dots or otherwise: these are protected marks, and a dotted copy is still a copy, so country flags stand in for them. Photos of aircraft are shown as their photographers published them, with their name and a link, and never copied or posted elsewhere. This site sets no cookie, runs no analytics, loads nothing from a third party; the colour you choose at the bottom of the page is kept in your browser alone.
Twenty-one languages
ZenithBoard’s web pages and this site exist in twenty-one languages, because the sky is the same everywhere and a receiver in Jakarta or Riga is as welcome as one in Lyon. English and French are written by the author; the other languages were translated with care and are being reviewed by native speakers. If you find a sentence that reads wrong in your language, the repository takes corrections gladly: every page is a plain text file.
Say thank you
ZenithBoard is free and will stay free. If it gave you an evening of looking up, a beer says thank you: it unlocks nothing, it gives no advantage, and it helps pay for the electricity of the server and the Pi. The button is at the bottom of every page, a simple link, with no script behind it.
Write to the author
Bugs, ideas and translations go to the ZenithBoard repository on GitHub, as an issue or a pull request. The repository of this site is separate; its README explains how a page is edited and published.
