Thunderclap takes users' privacy very seriously.
When you sign into Thunderclap with a social media account to support a campaign, you’re allowing Thunderclap to share a single message on your behalf. This is only the case when you click the button on the campaign page to support with Twitter, Facebook, or Tumblr. After the campaign is complete, we won’t post any additional messages.
Thunderclap supporters and organizers include President Barack Obama, the United Nations, the U.S. Department of State, and countless other public figures, organizations, and government agencies.
