How Free Cloud Drives Monetize Your Personal Data
Free cloud providers run automated background scripts across your drive:
Optical Character Recognition (OCR)
PDFs and tax forms are scanned for text, indexing salary info and social security numbers.
Facial Recognition Tagging
Family photos are indexed for facial features and location geotags for ad profiles.
Machine Learning Training
Private media files are fed into generative AI vision and language models.

BackupBox treats your cloud drive as a private vault. File contents are encrypted locally prior to hitting the cloud, rendering background scanning completely impossible.
- Zero OCR scanning on private PDFs and tax forms.
