#OPSEC365 214/365
Granting contact access doesn't expose your data. It exposes everyone else's.
Your address book is a social graph belonging to people who never consented. WhatsApp, LinkedIn, and TikTok have all used contact uploads to build graphs of non-users.
Cronk's aggregation problem: the app now knows your network position without you ever posting publicly.
A photo editor, game, or flashlight has no need for your contacts. Audit and revoke. #OPSEC365
