-The types of personal information your blog will collect
-How your blog will use that information (for example, to provide features or to improve the content)
-How long your blog will keep that information for
-How you will share personal information if it’s not necessary for providing services
-How you will contact individuals who have provided personal information to your blog and explain why it was shared
-What steps you will take to protect the privacy of individuals who choose to provide personal information to your blog
A good way to start is by looking at other blogs that have privacy policies and copying the sections that are most relevant to your blog. Once you have a rough draft of your policy, you can then go through and specify which information you want to collect, how it will be used, and how long it will be kept.
It is important to make sure that all of the information in your policy is clear and concise so that users know what they are agreeing to when they provide personal information to your blog. Finally, make sure to include contact information for both yourself and for people who users can contact if they have questions or concerns about their data.
