I analyzed Drime Cloud’s Vault feature, which they market as “zero-knowledge” with end-to-end encryption.

Their website claims “Only you can see your files. Not us, not anyone else.”

However, after a simple API inspection, I noticed all metadata is transmitted in plaintext:

• File and folder names
• File types and sizes
• Complete directory structure
• All timestamps Only file contents appear to be encrypted. This contradicts the industry definition of “zero-knowledge” encryption.

Full technical analysis with evidence:

Thought I’d put this out since my post on their subreddit got removed and my Reddit account shadow-banned for no apparent reason.

Be careful where you put your data.
