Changes to Subprocessors
PNDA may add, remove, or replace subprocessors as our platform evolves. We will update this page when subprocessor changes occur. For clients with an executed BAA or DPA, we will provide advance written notice of subprocessor changes as specified in the applicable agreement.
Mobile Data
Phone numbers and mobile opt-in data collected through the PNDA platform are never sold, rented, or shared with third parties or affiliates for marketing or promotional purposes. Mobile data is used solely to deliver services on behalf of the businesses that use PNDA.
