Mobile apps

Dropbox's own engineering writing describes an analytics pipeline that logs fine-grained user-behavior events in its mobile apps — button clicks, navigation across screens, sign-in failures, upload timing — to study 'complex user scenarios.'

Apple's App Store privacy 'nutrition labels,' introduced in December 2020, require apps to disclose their data collection — and the Dropbox app's label lists a broad range of data linked to the user's identity, from contact info and identifiers to usage data and diagnostics.
