How Zero-Knowledge Storage Works
Files are encrypted on your device before upload. The encryption keys never leave your device. The provider stores only ciphertext they cannot decrypt. This mirrors WeTalkin's approach to messaging.
Limitations to Consider
Zero-knowledge storage prevents server-side search, thumbnail generation, and collaborative editing. You trade some convenience for genuine privacy. File sharing requires sharing encryption keys or password-protected links.

Frequently Asked Questions
Can Google or Apple see my cloud files?
Yes. Standard Google Drive and iCloud can access your files for indexing, AI training, and legal compliance. Use zero-knowledge alternatives for sensitive documents.
What if I forget my encryption password?
With zero-knowledge storage, the provider cannot help you recover files if you lose your password. Secure backup of your recovery key is essential.
Can I share files from zero-knowledge storage?
Yes. Most providers offer password-protected sharing links or key-based sharing with other users of the same service.
