Our Principles and Policies will help you do this by explaining what’s required; these examples and explanations will help you understand how to put that into practice. We'll update this document frequently, so check back for new content.

Highlights of Changes and Clarifications in the new Developer Policies

• Provide a link to your privacy policy in the Info section of your Application Profile page and on every page of your application. (DPP I.1)
• You can evolve and develop your application, but don't repurpose it. (DPP II.6)
• Be sure users can easily report inappropriate content, and be responsive to their reports. (DPP IV.B.2)
• Don't undermine the integrity of the social graph by encouraging the creation of fake accounts or inauthentic friend connections. For example, don't gate content or provide rewards based on the number of a user's friends who also use your application. (DPP V.2)
• Don't prompt users to send invitations, requests, generate notifications, or use other Facebook communication channels immediately after a user allows access or returns to your application. (DPP V.4)

• Don't send multiple communications in response to a user's single action. (DPP V.7)
• Certain data fields you can submit to us through the API (e.g., the user_message parameter) must be reserved for content generated solely by the user. (DPP V.8)
• Don't prompt users to bookmark your application (e.g., by using a modal window or pop-up dialog), and instead provide users with a button for users to explicitly invoke any bookmark option you provide. (DPP V.10)
• If you provide users with the option to bookmark your application, you must use our bookmark button or design your own using a similar style and prominence. (DPP V.11)
• You must not display a Feed form unless a user has explicitly indicated an intention to share that content, by clicking a button or checking a box that clearly explains their content will be shared. (DPP VI.B.1)
