I still use it, but I stopped paying after archiving stopped working and none of my emails were answered anymore.

At that point it fell back to my original perpetual license it seems.

Edit: for those who wonder what it was all about it was a replacement for the social bookmarking service del.icio.us.

Part of the appeal for people like me who were also enthusiastic early WhatsApp adapters was the idea "I/we charge you money and provide a service, thats it, no ads/tracking funny business."
