要約

What are "personal projects?"

Personal projects are internal projects in Bitbucket used for organizing personal repositories. 

How are they different from regular Bitbucket projects?

Personal projects do not have a project settings page, where settings such as permissions can be configured.

The closest thing for viewing a personal project in the Bitbucket UI would be viewing the profile page, which would list the personal repositories of the currently logged on user.

To access the user profile page, click the user avatar on the upper right hand portion of the Bitbucket UI then select "View Profile".

When is a personal project created?

A personal project is automatically created in the background when any of these actions are done for the first time.

• The profile of a user is accessed.
  A user's profile is accessed by clicking on their name on several pages in Bitbucket, such as in commit listings and pull requests.

• REST APIs for accessing personal repositories are called.
  Accessing personal repositories via REST is achieved through the normal project-centric REST URLs using the user's slug prefixed by tilde as the project key. For example, to list personal repositories for user "jdoe", the GET call would be to the following URL:

  <BITBUCKET_URL>/rest/api/1.0/projects/~jdoe/repos
