I thought up all ideas published on this site myself. They should primarily serve as a source of inspiration.
I share them free of charge. As far as I(!) am concerned everybody is supposed to feel free to use them at will, change or develop them (free open source idea).
However, it is highly recommended and is the responsibility of the user that he or she ensures prior to the use that there are no circumstances (patents etc. by third parties), which may prevent a (free) use.

For legal and financial problems caused by lack of appropriate checks by the user, there is expressly no liability provided here!

If you achieve commercial success through the use of an idea of this site, it would be very kind of you if you remembered the idea supplier and give him an appreciation award or something like that :-)

You are very welcome to contact me via this site.
