“I do (not) need that Feature!” – Understanding Users’ Awareness and Control of Privacy
summary
A two‑week field study deploys a custom Android app to 132 participants to scan installed apps every two hours, push experience‑sampling prompts, and log 2,866 permission updates and 1,822 revocations; finding that participants correctly identify granted permissions only 49% of the time and falsely believe permissions are absent in 21% of cases. Revocations cluster in short bursts, target camera, microphone and location, mostly affect rarely used apps, and suggest promising moments for proactive privacy nudges.
