As an Agile Coach, I provided a free version as a ConsentBoard for the community when Covid held us in our home offices.
The free version was as secure as the moderated version, easy to use and free of tracking, obligations or other disadvantages that other solutions have. ConsentStorm© was my contribution in the Corona times. You could use ConsentStorm© for your business without hesitation.
We had to consider the certificates and other financial costs. Since there was no business model and Corona lost its grip, we decided to discontinue the free version.
