Proof of Delivery For Every Secured Transfer

For maximum guarantees you can enable E2EE+ per transfer. The encryption key never reaches our server: it lives only in the part of the download link after the # sign (browsers never forward fragments to servers). A database breach plus a server-secret leak still cannot decrypt these transfers. The trade-off: Office files can only be downloaded (not in-browser previewed) and forgetting your password makes your own past E2EE+ transfers unrecoverable from other devices.

The sender chooses one of three proof levels (Standard, Enhanced, Verifiable), each capturing only what is needed for that level of evidence. Portrait photo and full document details are ONLY included when the sender explicitly picks the Verifiable level AND the recipient consents. Files are deleted from our storage when the configured retention period expires.

Files are stored inside the EU via datacenters in France and Germany, designed for organisations that need to send confidential documents securely. Processing happens entirely under European data-protection law from start to finish.

AI-driven liveness detection blocks masks, printed photos, screen replays and deepfake video attacks. The recipient must be physically present, with subtle micro-movements and depth cues confirming a live human face, not a recording.

Data-minimisation: we collect only what is strictly necessary for the evidence claim. Lawful basis (article 6 GDPR): consent + legitimate interest. Recipients have full right-to-erasure of their biometric metadata at any time. A Data Protection Impact Assessment (DPIA) is available on request.

Each verified delivery gets an independent third-party timestamp from an external time stamp authority. The timestamp is cryptographically bound to the file hash plus the verification metadata, making backdating mathematically impossible, even by us.
