Hello! I use OSM for an app I build. I use Leaflet as a mapping library. Instead of showing OSM attribution on the map (bottom-right side), could I crearly declare that the maps are OSM in the 'About' tab of the app? |

So the relevant part of the OSM licence is section 4.3: if you Publicly Use a Produced Work, You must include a notice associated with the Produced Work reasonably calculated to make any Person that uses, views, accesses, interacts with, or is otherwise exposed to the Produced Work aware that Content was obtained from the Database, Derivative Database, or the Database as part of a Collective Database, and that it is available under this License. (emphasis mine) So if it's in the 'About' page will that ensure that "people that use the map" aware that it's OSM? I'm not sure it is. Putting it in the corner isn't a massive requirement, is it? 1
Exactly. If you're being given the best geodata in the world for free, it's really, really miserly and ungrateful to say "ok, yes, and I don't want to add a visible credit either". If you want to avoid showing a credit, you can phone TomTom or HERE and ask how much they'll charge for their data.

@Richard: It's not "miserly" to want to give users the best possible experience, and let's be frank: No one wants to have their screen space wasted on legalese. As a long-time OSM contributor, it makes me sad that OSM-based apps will always be uglier than they could be if it wasn't for the inflexible rules on attribution placement.

The best possible map experience is achieved by ensuring the best possible map data. To get that, we need the virtuous feedback loop: users are aware that their map is made from OSM data; they see something that can be added; they go to OSM and make that change; the map gets better; and so on. Visible attribution is how that happens: if it's squirreled away in an About box, people don't know to go to OSM to make the change. In an age of 2000x1000px mobile screens, a little '©OpenStreetMap' isn't "wasting screen space on legalese", it's ensuring that our map - and hence the app they're using - continues to improve. But this is better suited for the mailing lists. :)

An example: http://osm-nottingham.org.uk/ where the attribution is placed in a collapsed "attribution" to the left.
