Disable in custom posts types

My plugin doesn’t add any buttons automatically. You’ll need to place the shortcode ([jpshare]) for the sharing buttons to be displayed.
If you don’t want to add any buttons via my plugin, you can just not add any shortcode to your post content.

If you want to remove buttons added by the Jetpack plugin, you should be able to do so by going to Settings > Sharing in your dashboard.
If that doesn’t help, do not hesitate to start a new thread in the Jetpack support forums:

Thank you!
