lEEt/OS, ST-DOS and all userland programs that come with the standard distribution disk are licensed in the GPLv3
license. The GPLv3 license exists to protect the freedoms and rights of the end user, including but not limited to
the freedom of speech and self-expression, the right to privacy, the right to modify the software and use it in any way the user wants,
etc.
Sadly, in some cases the local laws conflict with these ideals. Sometimes this may even lead to legal problems
for those people who use the software. Some of those known caveats are listed on this page. You can propose more content

USA
In the state of California, starting from 1. January 2027 all operating systems that don't have age verification become
illegal. Using, distributing or owning copies or forks of these operating systems can lead to a $7500 fine per copy. A similar
law is also being proposed in Colorado. (27. February 2026)
ST-DOS does not verify the age of its user, nor does it even have any concept of user accounts by default.
EU
The CRA and Ecodesign directives make ST-DOS, lEEt/OS and all their standard userspace programs illegal as commercial products. They may still be used for non-commercial purposes.
Russia
Due to the sanctions against Russia, we cannot provide commercial support for ST-DOS, lEEt/OS and their related products for users in Russia. Unofficial non-commercial support is still available in the forum and IRC channel. We also accept contributions from all places.
