Frequently asked questions
What is zero-knowledge cloud storage?
Zero-knowledge cloud storage means that encryption keys are generated locally on your device, ensuring that the service provider has no technical way to access or read your stored files.
Is free cloud storage safe to use?
Yes, reputable providers use standard transport encryption and data centre security, though free tiers often lack end-to-end encryption and have strict storage limits.
Can I access my cloud storage offline?
Most cloud storage applications allow you to mark specific files or folders for offline access, downloading local copies to your device for viewing without an internet connection.
