Pinterest can alter the rules governing your account and content at any time, and simply continuing to use the service — even without actively reviewing the new terms — constitutes your legal agreement to them.
By using Pinterest, you grant the platform a wide-ranging license to use, display, and distribute your photos and content across their services. US users are subject to mandatory arbitration and cannot join class action lawsuits against Pinterest, which significantly limits legal recourse. You can opt out of the arbitration clause by sending written notice to Pinterest within 30 days of first accepting these terms.
