US users are subject to California law for any legal disputes with Dropbox, which may limit options available under their own state's laws. Non-US users should check whether local laws provide different or stronger protections.
Dropbox's terms grant the company a broad license to your uploaded content to operate the service, and limit the company's liability for data loss or service interruptions. US users are required to resolve disputes through binding arbitration and waive the right to participate in class action lawsuits, significantly limiting legal recourse. You can opt out of arbitration by sending written notice to Dropbox within 30 days of first agreeing to these terms.
