While Contextual Privacy Policies (CPPs) present information at the point of risk, they often act as static displays that fail to engage users or prompt active decision making. To address these limitations, we construct a design space for reflective CPPs based on the Reflective Thinking Framework. Through three expert workshops, we mapped the hypothetical user interaction around CPPs to three stages of reflection: Experience (triggering surprise via contextual cues), Reflection (supporting inquiry through risk scenarios), and Action (empowering users with granular controls). We instantiated this design space with Conflect, a high-fidelity mobile prototype featuring non-intrusive sidebar alerts and dynamically synthesized risk explanations. A user study (N=48) comparing Conflect against state-of-the-art CPP designs shows that our reflective approach effectively reduces users' perceived habitual action and improves privacy comprehension. Notably, Conflect facilitates these gains without increasing cognitive load or compromising usability compared to CPPs.<\/jats:p>","DOI":"10.56553\/popets-2026-0146","type":"journal-article","created":{"date-parts":[[2026,7,14]],"date-time":"2026-07-14T21:23:59Z","timestamp":1784064239000},"page":"814-836","source":"Crossref","is-referenced-by-count":0,"title":["Designing Reflective Thinking-Based Contextual Privacy Policy for Mobile Applications"],"prefix":"10.56553","volume":"2026","author":[{"given":"Shuning","family":"Zhang","sequence":"first","affiliation":[{"name":"Tsinghua University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sixing","family":"Tao","sequence":"additional","affiliation":[{"name":"University of Washington"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eve","family":"He","sequence":"additional","affiliation":[{"name":"University of Wisconsin-Madison"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuting","family":"Yang","sequence":"additional","affiliation":[{"name":"University of Michigan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Ma","sequence":"additional","affiliation":[{"name":"The University of Melbourne"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ailei","family":"Wang","sequence":"additional","affiliation":[{"name":"Tsinghua University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Yi","sequence":"additional","affiliation":[{"name":"Tsinghua University and Beijing Academy of Artificial Intelligence"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hewu","family":"Li","sequence":"additional","affiliation":[{"name":"Tsinghua University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"35752","published-online":{"date-parts":[[2026,10]]},"container-title":["Proceedings on Privacy Enhancing Technologies"],"original-title":[],"deposited":{"date-parts":[[2026,7,14]],"date-time":"2026-07-14T21:24:09Z","timestamp":1784064249000},"score":1,"resource":{"primary":{"URL":"https:\/\/petsymposium.org\/popets\/2026\/popets-2026-0146.php"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,10]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2026,10]]}},"alternative-id":["10.56553\/popets-2026-0146"],"URL":"https:\/\/doi.org\/10.56553\/popets-2026-0146","relation":{},"ISSN":["2299-0984"],"issn-type":[{"value":"2299-0984","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,10]]}}}
