Based on open-ended survey data of 400 women who self-identify as either Black or Latinx, this study examines women’s digital media sharing practices in romantic relationships amid a growing trend towards the personalization of digital technologies. Communication Privacy Management (CPM) theory as well as scholarship on privacy and trust in romantic relationships frame our work. Approximately 56% of participants said romantic partners should not have access to each other’s social media accounts, 24% said they should, and 20%, said that access needed to be negotiated based on situational and personal factors (e.g., seriousness of the relationship, special circumstances). Justifications for sharing included having nothing to hide, trust, and a desire for open communication in the relationship. Explanatory themes for keeping social media and smartphone access private focused on trust, privacy, risk of conflict, and the need to respect a person’s individuality and personal boundaries. Interestingly, trust was a major motivator for both granting and denying access. We make sense of this duality of trust through the introduction of a trust/privacy dialectic relationship that extends current scholarship on CPM in romantic relationships.
