Secure Legal Courier.
Chain of Custody Built-In.

Stop relying on consumer file-sharing or mailing physical hard drives. Send massive deposition videos and eDiscovery files (500GB+) to opposing counsel securely. Zero-knowledge encryption, WORM-compliant downloads, and immutable IP audit logs.

  • Upload massive raw video files directly from your browser.
  • Zero-Knowledge Escrow protects you from data host liability.
  • Recipient IP & Timestamp logged permanently upon download.

eDiscovery Portal

Access the zero-knowledge escrow portal to upload a new matter or retrieve a secured payload.

Send a File Retrieve File

No subscription required. Pay-per-transfer.

Engineered for ABA Compliance.

Designed specifically to solve the massive file bottleneck in litigation support while maintaining a strict, defensible chain of custody.

Massive Payload Escrow

Traditional cloud drives crash on 100GB+ folders. Our multipart edge-upload technology allows you to drag and drop massive raw 4K deposition videos and synchronized transcripts with zero timeouts.

Immutable Audit Logs

Anonymous downloads ruin evidence admissibility. We mandate PIN-based access for recipients and permanently log their IP address, browser agent, and exact timestamp to the matter’s ledger.

Zero-Knowledge Security

We are a courier, not a host. Files are encrypted and shredded across a decentralized network before leaving your browser. We cannot view your files, shielding you from third-party host liability.

Defensible Chain of Custody

When you email a Dropbox link, you lose control of the data. When you send a physical hard drive, you risk transit loss and breach of confidentiality (ABA Formal Opinion 477).

SendDeposition forces a Write-Once, Read-Many (WORM) compliant workflow. The payload is sealed in escrow. To access it, opposing counsel must authenticate. The moment the encrypted stream begins, the transaction is cryptographically logged on your dashboard.

Files are automatically pruned from the network after 7 days to eliminate stagnant data risks.

1. “Carrier vs. Host” Liability Shield:
We operate strictly as a data courier, not a host. By utilizing a 7-day automatic pruning script alongside zero-knowledge payload handling, we do not archive data at rest. This structural design ensures that the sending firm retains full ownership and control over compliance, shielding our infrastructure (and the firm) from long-term data breach liabilities associated with permanent cloud storage.

2. End-to-End Encryption (Powered by Storj):
Before leaving the user’s browser, the deposition payload is encrypted using AES-256-GCM. It is then erasure-coded and fragmented across thousands of decentralized global edge nodes. SendDeposition never possesses the decryption keys to inspect the payload, ensuring absolute confidentiality under attorney-client privilege guidelines.

3. Immutable eDiscovery Audit Engine:
Our backend enforces a hard gate on the `sd_handle_download` hook. Before dispensing the cryptographically signed S3 download URL, the system permanently writes the requester’s IP address (`$_SERVER[‘REMOTE_ADDR’]`), Timestamp, and User Agent directly into the `sd_audit_logs` SQL table. This ensures a Write-Once, Read-Many (WORM) compliant record that is legally defensible in court.

4. Unlimited File Size Capability:
Legacy tools fail on large files due to server timeouts. Our frontend utilizes multipart chunking (`CHUNK_SIZE = 50MB`). These chunks bypass our middle-tier server completely, executing `PUT` requests directly to the decentralized edge network in parallel. This allows an unlimited payload size, bounded only by the user’s local internet uplink speed.
