No. If the closed layer you have your users create is in any way "based" on OpenStreetMap, then we would call that a "derived database", and you would have to release it under the same free license that OSM comes under. This would for example be the case if your users drew areas onto the map and added information to them, for example something like "This area is a pleasant area for taking a walk". Because your users would actually incorporate the geometry they see on OSM into your new layer, the data would be derived from OSM. It would be a different thing if the data that your users generate was created without using the OSM base map as a reference. For example, if your user pushed a button on their smartphone that says "the GPS location where I currently am is really a pleasant spot for taking a walk", and you would then collect these nuggets and generate data from them, and then just *display* your independently generated data on top of OSM. In that case, your layer would not have to be released because OSM was not used in creating it. Was that layperson friendly enough?
