Why CRYMBL and how does it work?

Expert voices

What regulators and analysts require

End-to-end encryption, keys in the customer's hands, European law — what experts and authorities require for sensitive data is standard at CRYMBL.

“Germany's data protection authorities require that anyone transmitting high-risk data must use end-to-end encryption — and point to secure portals where email encryption fails in practice.” – That is exactly what CRYMBL was built for.

German Data Protection Conference (DSK)

Guidance "Transmission by email" · Federal and state supervisory authorities

“Since the Schrems II ruling, the European Data Protection Board has required effective encryption for data transfers, with keys that stay beyond the reach of foreign authorities.” – CRYMBL fulfils this zero-knowledge principle by design.

Recommendations 01/2020 (Schrems II) · EDPB, Brussels

“The BSI makes it clear: confidentiality in data exchange can only be ensured through end-to-end encryption — data is encrypted when sent and only decrypted again at the recipient.” – CRYMBL works exactly on this principle.

Zero-knowledge principle: Even CRYMBL cannot read your content.
Security doesn’t have to be loud – it just has to be reliable.

Data storage on our servers – Zero-Knowledge by Design.

Your data belongs only to you – for exactly one second.

Whether login data, passwords, PINs or sensitive documents – with CRYMBL you can send messages and files so that they can only be read or downloaded once and are then automatically deleted.

Unlike email or traditional cloud tools, CRYMBL never stores in plain text. Everything is encrypted directly in your browser before it leaves your device – and only the recipient has the key.
