If you came to this page, then you want to financially support the project. This is very nice and means that I do not waste my time.

By supporting the project, you are helping its development, so I can allocate more time for new research and refinement of new functions.

Below is a list of ways you can donate money to the development of the project.

You can also simply click on one of the advertising links (AdBlock should be turned off).

If you do not want your name to appear in the list of donators - send me an email to with some payment details (for example amount or email of payment). You can also indicate in the notes to the payment that you do not want your name displayed on the site.
