What's up with PERIMON?
The website PERIMON will be discontinued on 30th Jun 2015 (further information
). Since 30th Jun 2014 it is not possible to buy new cycles. The free-of-charge version of PERIMON doesn't show fertility information
Are there alternatives? There are some websites about NFP ("natural family planning", at least in German) that provide good and more complex alternatives. You have to search for them since we only now German alternatives.
If you feel nostalgic and like old software you can download the old PERIMON-DOS
that you should be able to use for at least a couple of years. PERIMON-DOS is a trimmed version and the predecessor of the current PERIMON.
