You can limit whether others can include your works in their collections using the methods below.
There are two ways to adjust this setting: you can either apply the setting to all your works at once or to each work individually.
1. Apply the setting to all your works
Go to Settings > Privacy > Include works in collections and turn this setting off to prevent all of your works from being added to other people's collections.
Turning this setting off will not remove your works from collections they’ve already been added to.
To remove your work from an existing collection, see "How do I remove my work from someone's collection?"
2. Apply the setting to each work individually
When posting or editing a work, you can choose whether or not to allow it to be included in other people's collections.
To prevent inclusion, uncheck "Allow your works to be featured in other people's collections" at the bottom of the posting or editing page.
Changing this setting will not automatically remove the work from collections it has already been added to.
To remove your work from an existing collection, see "How do I remove my work from someone's collection?"
*You can still include your own works in your collections even if this setting is disabled.
*Regardless of your settings, accounts you have blocked will not be able to add your works to their collections.
*This setting is also available in the pixiv app.
