Developer Content Policies
You agree to comply with the Google+ Platform Developer Policies ("Developer Policies") set forth at http://developers.google.com/+/policies (or other such URL as Google may provide for this purpose from time to time). The content of your API Client, including any content supplied by your users or other content providers, must follow the Google+ User Content and Conduct Policy at http://www.google.com/intl/en/+/policy/content.html.
You may not use user data from our APIs for advertising purposes, unless: (i) you are explicitly authorized by Google, or (ii) you are using an advertising solution that Google provides for this purpose. You may not, and may not permit any third party to, sell or transmit any user data received from our APIs (including anonymized, aggregate or derivative data) to any third-party ad network or service, data broker, or other advertising or marketing provider.
Directly Sold Ads
Notwithstanding the foregoing or section B(1) of the Google+ Platform Developer Policies, and provided that you don’t operate as an ad network, you may use user data from our APIs to target ads within your API Client where you have sold the ad slot to the advertiser directly (“Directly Sold Ads”), and you may make anonymized user data from our APIs available to a third party solely to enable that third party to serve Directly Sold Ads to your API Client.
If you have third party advertising in your API Client which is provided by a Google advertising solution, you must use an approved Third-Party Ad Serving ("3PAS") provider subject to Google's current 3PAS policies at http://adwords.google.com/support/aw/bin/answer.py?hl=en&answer=94230.
Google reserves the right to block any advertising provider, or any advertisement, from your API Client for any reason, including but not limited to: (i) user abuse concerns regarding an advertisement or advertising provider; or (ii) an advertising provider preventing reciprocal ad serving by Google.
Fees that you charge
For API Clients that appear while a Google+ user is on a website that is served from a google.com domain ("Google+ Canvas Applications"), if you collect payments in connection with virtual goods or functionality of your Google+ Canvas Applications, you must use Google In-App Payments in accordance with the applicable terms of service at https://checkout.google.com/termsOfService?type=Seller, policies at https://checkout.google.com/seller/policies.html, and transaction fee schedule at https://checkout.google.com/seller/fees.html. Google reserves the right in the future to charge you additional fees for payments in connection with your Google+ Canvas Applications.
Object Code License
Any Google-provided object code that calls the APIs shall be considered part of the APIs. Subject to these terms, you may copy and distribute this code solely for inclusion as part of your API Client(s). Google and its licensors own all right, title and interest, including all intellectual property and other proprietary rights, in and to this code.
