NT² — Null Trust² — is a structured digital asset vault for receiving, storing, and sharing the data that matters most: financial accounts, cryptocurrency keys, identity documents, and high-value credentials.
Why we built it
Most people still store sensitive information in the wrong places: phone notes, unencrypted spreadsheets, or generic password managers that treat a 24-word mnemonic like a sticky note. When they need to hand data to someone else—a landlord, a contractor, a family member—they fall back on something worse: email attachments, messaging-app photos, or cloud links with no structure and no expiry.
Cloud-first tools require trust in a provider's infrastructure, disappear when the network does, and were never designed for person-to-person handoff of API keys, national-ID scans, or bank details.
NT² Vault sits between a blank canvas (Notion) and a login autofill tool (1Password). It gives you structured templates and military-grade encryption on your device—and a sharing model built for when secrets must reach another human, not just sit in a drawer.
Receive, store, and share
NT² is one product story with three jobs:
| Pillar | What you do | Examples |
|---|---|---|
| Receive | Accept structured assets from others into your vault | Bank details from family in Vault Inbox; import a .nt2share from a contractor; scan a QR or deep link, then accept or decline |
| Store | Keep secrets structured and encrypted locally | Mnemonic in a Crypto template; passport metadata + scan in Document |
| Share | Hand off ciphertext under your control—or show only what the moment requires | API keys to a co-founder; ID front/back to a landlord; in-person verification with last-four digits via safe presentation |
Sharing is not “export everything to a zip and hope.” It is explicit: you pick the asset (or fields), choose a mode, and the recipient decrypts with their vault or a share passphrase you set separately from your master password. NT² servers, when used, see ciphertext only—never plaintext.
For receive, store, and share examples, see Use cases.
Sharing modes (overview)
| Way to share | Best for | Recipient needs NT²? |
|---|---|---|
| Vault to vault | Ongoing trust (family, business partner) | Yes (accept in Inbox) |
| Encrypted link | One-time handoff to accountant, lawyer, contractor | No (browser + passphrase) |
Share file (.nt2share) | AirDrop, USB, email attachment offline | No |
| Safe presentation | In-person or video call verification | No (view-only, redacted) |
Full backup (.nt2backup) | Trusted device migration or estate handoff | Yes (importer) |
What's available now: Local storage, attachments, .nt2backup backup, Vault Inbox, trusted contacts, Receive/Send sharing, and safe presentation work in the app today.
Design pillars
Structured
Purpose-built fields for crypto wallets, bank accounts, identity documents, and credentials—not a blank notes app. Structure matters twice: for copy buttons at your desk, and for field-level sharing later (send only routing number, not the full item).
Local-first
Your vault runs in the browser with encrypted SQLite on your device. Daily use needs no server and works offline. Sharing can be offline too (.nt2share file) or use optional cloud delivery that never sees your plaintext.
Zero-knowledge
Your master password and keys never leave the browser. NT² cannot read your vault contents—even with a court order. Share passphrases for links are separate secrets; compromising a share link does not reveal your master password.
Who it is for
- Crypto holders who want mnemonics in validated fields—not plain text notes.
- Expats and travelers organizing passport metadata and encrypted scans—then sharing one package with an embassy contact if needed.
- Privacy-conscious users who prefer local storage with optional blind sync.
- Budget-minded households seeking structured security without enterprise pricing.
- Anyone who today texts ID photos or pastes API keys in Slack and wants a structured, encrypted alternative with accept/decline and expiry.
Premium sync and billing are designed for low server cost so we can offer honest pricing at $2.99/month.
What we are not
- Not a bank or cryptocurrency custodian—we never hold your assets.
- Not a browser extension that autofills website logins in v1.
- Not able to reset your master password—that trade-off is what makes zero-knowledge real.
- Not a file-sync or team-drive product—we do not mirror your Desktop folder; we vault typed assets you choose to share.
Roadmap highlights
- Cross-device encrypted sync (Premium) — ciphertext blobs; server blind to content.
- Safe presentation — redacted cards and timed reveal for in-person verification.
- Native apps (desktop and mobile) — see Desktop and mobile apps.
- WebAuthn unlock enhancements.

se.nt2.me — sent to me
The vault app lives at se.nt2.me—not a generic app subdomain. Read across the hostname: se + nt → sent; 2 → to; me → me. That is the URL for receiving links, QR codes, and third-party handoffs (https://se.nt2.me/?m=…). Product pages and SEO stay on nt2.me. Read the full story: Sent to me.
How we build
NT² is an indie product: one person ships and maintains it, with AI assistance for code, documentation, and translation drafts. That speeds iteration—it does not replace accountability.
Humans own product decisions, merges, releases, and security-sensitive changes. Your vault plaintext never goes to AI services; encryption and zero-knowledge boundaries stay on your device. Support replies are human-reviewed before send—staff may use draft assist, but NT² does not auto-reply to users with an LLM.
