Lucky Patcher serves very different purposes and most of them don’t break any rules. For example, thanks to this modifier you can clone certain applications to use two instances of the same app simultaneously on the same device.
However, other uses of this and similar tools are unethical. Many users are known to use applications like Lucky Patcher to remove ads or avoid payments. Such uses could be classified as illegal. Because of this, it is impossible to find such software on official stores like Google Play or App Gallery.
Don’t forget that developers, graphic designers, and other professionals in the industry, like everyone else, make a living from their work. The fact that their works are intangible doesn’t make them any less valuable. Likewise, their work doesn’t end when they release an app or game. Rather, many of them offer support, release updates, fix bugs, and even offer enhancements. In the case of online games, the servers must be kept active. Of course, none of this is free.
In short, whether you use Lucky Patcher legally or illegally is up to you. Depending on how you use it, you’re either benefiting from a great tool or stealing from someone else.
