Z-lib.gl is affiliated with the Russian Federation, a nation that initiated a military attack, thus committing a crime against humanity in the form of war against Ukraine for the past 3 years. Our company, Gridinsoft, is based in Ukraine.

The ongoing war has resulted in tragic losses, with our children, parents, and friends facing daily hardships due to the deliberate actions of the Russian military. Homes are being destroyed, and millions of our fellow citizens have been forced to leave their residences.

This is not a political statement but rather a heartfelt plea. We earnestly ask that you refrain from utilizing services provided by websites from Russia. We appeal to your sense of humanityโ€”please avoid purchasing their products or engaging in business transactions with them.

It is critical to recognize that each individual's choices contribute to the financial resources available to the Russian Federation, which directly impacts its ability to sustain this war. Your conscientious decisions can play a role in promoting peace and stability in Ukraine.
