I think the example agreement is a great way to generate ideas and provide a benchmark. As promised, what appears to be a few years ago, here is a confidentiality agreement that can use non-profit organizations. This serves only as a starting point and can be done more or less formally depending on the needs of your organizations. It can also be adapted to volunteers. As I said, I wanted to continue and straighten something, because I promised to post something forever. Therefore, it is still being developed. But please, feel free to make suggestions.
