Scholarship on politics and romance has found that political homophily between couples is due to social sorting (i.e., people seeking politically like‐minded partners from the outset). However, it remains unclear how people do so in an online context. Based on interviews with dating app users in Hong Kong, this study explores individuals' self‐presentation and partner‐vetting strategies in their quests for politically like‐minded partners in a highly polarized political environment. The study reveals that political participation and knowledge have become sexual capital on dating apps, and self‐censorship has begun to emerge in citizens' private use of social media in the city. Finally, this study proposes a typology along the dimensions of effectiveness and riskiness to categorize various self‐presentation and partner‐vetting strategies.
