I really hope this is the right forum, if not you have to excuse me.
I am planning to build a commercial service (in this case a mobile app) that uses content from Foursquare and presents it to my users in a new way. Am I allowed to do this without breaking any kind of "Terms Of User agreement"?
The license agreement found on: http://foursquare.com/legal/terms clearly states that:
Subject to these Terms of Use, foursquare grants each user of the Site and/or Service a worldwide, non-exclusive, non-sublicensable and non-transferable license to use the Content, solely for personal, non-commercial use.
If this is the case, how come there are tons of application & services out there today using the Foursquare API and content in different ways? Many of these application & services are being promoted by Foursquare themselves at their website /apps.
In addition, would you really create an API if nobody could use it unless it was for private use?
