What is Zero-Knowledge?
Zero-knowledge means we have zero knowledge of your data. Not just policy - mathematical impossibility.
Traditional Cloud
• Files encrypted in transit and at rest, but decrypted on their servers for processing
• Provider has encryption keys
• Can access your files anytime
• Can comply with data requests
• Can scan and analyze content
Nygma (Zero-Knowledge)
• Files encrypted on your device before they ever leave. Keys never transmitted.
• You control encryption keys
• Provider cannot access files
• Cannot comply with data requests
• Cannot scan or analyze content
The Key Difference
Traditional cloud providers say "we encrypt your data" but they hold the keys. That is like locking your diary in a safe and giving them the combination.
With Nygma, encryption happens before upload. We store gibberish. You keep the only key.
Result:
Even if hackers breach our servers, they get encrypted blobs they cannot decrypt. Your data stays safe.

Why Zero-Knowledge Matters
True Privacy
Your files are mathematically impossible for us to access, even if we wanted to
No Surveillance
We cannot scan, analyze, or mine your data because we cannot see it
Breach Protection
If our servers are compromised, attackers get useless encrypted blobs
No Backdoors
No master keys exist, not even for legitimate recovery requests
What We Cannot Do
Limitations by design. These are features, not bugs.
Read your files
We do not have decryption keys
Reset your password
We never stored it in the first place
Comply with data requests
Court orders do not help if we do not have keys
Scan your content
No AI scanning, no content filtering possible
Provide access to anyone
If you lose password and recovery key, data is lost forever
This is not a limitation - it is a guarantee
True security means we share your level of access: ZERO. That is why you can trust Nygma.
