Arkin Vault stores, gates, releases, and proves access to your most confidential documents — and the software builds you ship — agreement-gated release and a complete evidence trail, in one governed vault.
Working with select law & advisory firms. India + US workflows supported.
Locked until the NDA is complete
NDA signed in the browser. Release condition met.
Deliver large, sensitive files — no public links, far beyond email attachment limits.
Hold release until the NDA is signed in the browser, bound to the document.
Every view, download, and signature logged to the recipient.
Agreement, files, and access trail kept together as one evidence record.
A transfer tool, a signing tool, and a records system — one governed flow instead of three. Already invested in DocuSign, Adobe Sign, Dropbox, or SharePoint? Keep them — Arkin Vault works alongside and governs the release.
What it does
The signature capability is agreement-gated release. Around it sits everything a confidential workflow needs to stay controlled and provable — from intake to evidence.
Create secure rooms by client, matter, deal, project, vendor, or research file. An NDA room gates every document inside it automatically.
Documents stay sealed until an NDA, engagement letter, or acknowledgement is complete — signed in the browser and bound to the exact agreement text.
Recipient verification, watermarking, expiry, view limits, revocation, and page-level controls — clean reads when you want them, locked down when you don't.
Every view, download, and signature — with identity, IP, timestamp, and page number. Nothing a recipient does goes off the record.
The executed agreement, the released documents, and the access trail — preserved together and exportable as an evidence pack (PDF + JSON).
Expiry-driven lifecycle, folder retention windows, scheduled purge of expired materials — and deletion suspended the moment a legal hold applies, with the hold itself on the audit trail.
Not just documents. Ship a firmware image, SDK, installer, or full build as the exact bytes — up to 1 GB, malware-scanned and SHA-256–fingerprinted, behind the same agreement gate. The recipient can verify they got precisely what you sent, unaltered.
The operating surface
The screens below are the real product: the governed repository, the per-document controls, and the access trail that becomes your evidence.

Who it's for
Three professions live this problem every day. The same governed exchange works for many more.
Client disclosures, matter exchanges, expert and settlement files, vendor confidentiality — with the executed agreement and access trail held as evidence.
Arkin Vault for law firms →Engagement letters, tax records, audit handoffs, client document rooms — gated on the engagement and preserved for the file.
Arkin Vault for accounting →Diligence rooms, customer NDAs, IP disclosures, board and founder documents — released only after the NDA, tracked to the recipient.
Arkin Vault for founders →Vertical-specific features — HIPAA-grade BAAs, FERPA-aware records, sector-specific evidence packs — are roadmap items. The core agreement-gated release workflow serves all of these segments today.
Purpose-built flow · Authors & literary agents
The same governed exchange, shaped for authors. Upload your manuscript — EPUB, Word, or PDF — gate it behind your own NDA, and send it to an agent. No visible watermark to break the read, and a quiet delivery confirmation so you know it arrived — without hovering over anyone's shoulder.
For agents — every manuscript arrives with the author's NDA already signed and the confidentiality terms settled before you open it. Read on your own time, raise your questions, and reply — the record protects your confidentiality too, and no submitter is watching over your shoulder.
Where Arkin Vault fits
E-sign gets a document signed. Data rooms store and share it. Arkin Vault decides whether it can open at all — and proves the whole exchange in one record.
DocuSign, Dropbox Sign, SignIQ…
Get a document signed. The job ends at the signature — they don’t gate whether the file can be opened, and the record is a per-signature certificate, not the whole disclosure.
Firmex, Datasite, iDeals…
Store and share files with access controls — but heavyweight and M&A-priced, the agreement isn’t the release condition, and there’s no single evidence artifact tying it together.
Governed document control
The agreement is the gate — nothing opens until it’s met. Every view, download, and signature is logged to the recipient, and one Evidence Pack (PDF + JSON) proves it. Works alongside the e-sign tool and drive you already use.

Starting fresh, Arkin Vault covers the whole confidential-exchange flow on its own. Already invested in a signing tool or a drive? It works alongside them — sign where you sign today, store where you store today, and let Arkin Vault govern the release and hold the record.

Real implementation details, because on a confidential-document platform vagueness is the red flag.
