Why Consumer Family Storage Leaks Private Photos
Most consumer family plan$29.99/mos prioritize shared photo feeds over privacy:
Shared Camera Roll Feeds
Uploading photos automatically pushes images to family stream widgets.
Shared Master Keys
Plan owners hold admin keys capable of viewing all member folders.
Lack of Individual Folder Passcodes
Spouses or children can browse private financial folders.
1. Individual Encryption Keys per Family Profile
Even though your family draws from the same storage pool, every member's files are encrypted with unique private keys. Spouses, children, or relatives cannot view your personal documents.
- Cryptographic key isolation for every family profile.
- No automated shared photo streams or accidental file leaks.
- Host manages storage allocation, not private file access.
