Data donation tools (overview paper)
We describe our approach and datasets for data donation across platforms.
Tools
A few public tools and demos we’ve built—mostly around privacy‑preserving data donation and mobile data collection.
WhatsApp Explorer
Collects WhatsApp data at scale via a QR‑code onboarding flow; enables group selection for research studies.
WhatsViral (Android)
Identifies viral content on WhatsApp via on‑device hashing; supports interventions via notifications.
YouTube data donation
Uses Google Takeout to streamline donation of watch and search history for research.
Telegram Watch
Authenticates with Telegram and lets participants choose the groups/channels they wish to donate.
Diaspora Watch (Facebook)
Facebook app that collects group/page data with participant consent; enables CrowdTangle‑based analysis.
Social Media Metadata Research (Android)
Instrumentation for Instagram experiments—collect feed data and test interventions within a companion app.
Mobile social‑media collection (R&D)
Explores Android accessibility for privacy‑aware collection across WhatsApp, Facebook, YouTube, and the browser.
Uber auditing tools
