You may be bound by new terms you haven't explicitly reviewed or consented to, simply by continuing to use WhatsApp after a change is made.
WhatsApp's Terms of Service grant the company a broad license to use content you share on the platform and reserve the right to suspend or terminate your account at any time. US users are subject to binding arbitration and class action waivers, significantly limiting legal recourse. You can review and adjust your privacy and data settings within the WhatsApp app under Settings > Privacy.
