Free, for personal and professional use
You may download Fukon, install it on as many computers as you like and use it at home or for work, also for paid jobs, without paying, registering or asking.
Your photos are yours
Fukon claims nothing on what you make with it: the photos, the edits and the exported files are yours, without watermarks or limits.
What is not allowed
Selling Fukon or asking money for it, passing it off as your own, or giving away changed copies of it. To share it, point people to this website: they will get the latest version, with the files whose SHA-256 is published here.
No warranty
Fukon is provided as it is, without any warranty. It never changes your RAW files, but it is made by one person and can have bugs: keep backups of your photos, as with any program. The author is not liable for damage or loss of data that come from using it, within the limits that the law allows.
Software of others inside Fukon
Fukon uses LibRaw (LGPL 2.1 or CDDL 1.0, as a separate library), the lensfun database of lenses (CC BY-SA 3.0, as separate files), libwebp, libavif with aom and libjxl (BSD licenses, as separate programs) and SQLite (public domain). Each keeps its own license: the texts are in the “licenses” folder next to the program, and the About window lists them.
Donations
Donations are voluntary: they are never asked for, they do not unlock anything and they create no obligations, for you or for the author.
