Capsule by NoData — Cryptographic control layer for all data.

B2B Document Sharing

Secure Channel enables businesses to share sensitive documents with clients in a fully encrypted manner. The agent uploads, the client views - and the document auto-deletes.

◆ Features

🔐

Encrypted Upload

The professional uploads an encrypted document. Encryption happens on the client device - the server never sees the content.

🔗

Link + Access Code

The recipient gets a link and an access code separately. The document is decrypted in the browser, viewed, and auto-deleted.

📋

Auto-Delete + TTL

Document auto-deletes after viewing or when TTL expires. Zero trace left on the server.

🧾

Delivery Proof

Every document gets a cryptographic delivery proof - a full event timeline with a SHA-256 signature that cannot be forged.

◆ Use Cases

⚖️

Law Firms

Share confidential documents with clients. The client views via link + access code - no app download, no account needed.

💰

Financial Advisors

Share reports, forecasts, and recommendations in an encrypted channel. Auto-TTL ensures documents do not persist indefinitely.

🩺

Healthcare

Transfer test results, prescriptions, and medical documents securely. Fully encrypted and compliant with data protection regulations.

◆ Delivery Proof

Every Document - Delivery Proof

Every document sent through Secure Channel automatically gets a cryptographic delivery proof. The server never sees content, never stores IPs, never keeps names - only proof that delivery happened.
