AES-256-GCM encrypted · offline

Privacy Pledge

Zero data leaves your device — by default

In its default state, GoVault makes zero network requests. Your financial data, passwords, and documents are encrypted with AES-256-GCM and stored exclusively in your browser's localStorage. No server receives anything. No analytics. No telemetry. Not even an error log reaches the outside world.

Features

Built for real privacy

GoVault is not a web app that stores your data somewhere safer. It is the safe — running entirely inside your browser, with no external dependencies.

AES-256-GCM Encryption

Every record is encrypted before writing to storage. Your PIN derives a 256-bit key via PBKDF2 with 200,000 iterations — never stored, derived at runtime.

Local-First Architecture

No analytics. No telemetry. The entire application is a single HTML file — every line of code is readable and auditable. Optional E2E encrypted cloud sync for multi-device use.

Biometric Unlock

Register your device fingerprint or Face ID via WebAuthn. Unlock the vault instantly without re-entering your PIN on every session.

Encrypted Backups

Export your entire vault as an encrypted file. Import it on any device. The backup is as secure as the vault — meaningless ciphertext without your PIN.

Auto-Lock & PIN Guard

Vault locks automatically after 2 minutes of inactivity. Wrong PIN shakes the dots and clears session memory. No brute-force window.

Installable PWA

Install GoVault on your device like a native app. Works completely offline after install. No app store, no update subscriptions.

Fully Secure Mode

Enable a single toggle in Settings to disable all cloud sync and auto-updates. The vault becomes completely air-gapped — no network activity of any kind, ever.

Encryption

How your data is protected

GoVault uses the WebCrypto API — the same browser-native cryptography used by banks. No third-party crypto libraries.

Encryption Specification WebCrypto API · NIST-approved

Algorithm	AES-256-GCM (Galois/Counter Mode)
Key Length	256 bits
Key Derivation	PBKDF2 + SHA-256
Iterations	200,000
Salt	Random 128-bit, stored with ciphertext
IV / Nonce	Random 96-bit per write operation
PIN Storage	Session memory only — never written to disk
Network Calls	None in local mode · sync endpoint only when cloud sync is enabled
Cloud Storage	None in local mode · optional E2E encrypted sync (Neon PostgreSQL, Singapore)
Cloud Sync	Opt-in · AES-256-GCM encrypted before leaving device · server sees ciphertext only
Fully Secure Mode	In-app toggle that disables all network activity — zero-network, air-gapped vault
Default Network Calls	None — zero requests in local mode; sync endpoint only when cloud sync is explicitly enabled

Modules

Everything in one vault

Six purpose-built modules for your complete financial picture. All encrypted. All local.

Transactions

Log income and expenses with custom categories. Monthly spending breakdowns and trend charts.

Bank Accounts

Track balances across multiple banks. Fixed deposit maturity dates and interest rates.

Credit Cards

Credit limit, outstanding balance, and payment due dates for every card in one place.

Passwords

Encrypted vault for login credentials. Stored as AES ciphertext — never readable without your PIN.

Documents

Store Aadhaar, PAN, Driving Licence, and Voter ID details encrypted and at your fingertips.

Net Worth

Real-time dashboard of assets, liabilities and net worth with monthly trend visualization.

How it works

Zero setup. Instant privacy.

No onboarding flow. No email. No cloud sync. Open the file, set a PIN, and your encrypted vault is ready in seconds.

Open or Download

Use it directly in your browser, or download the single HTML file. Works in Chrome, Safari, Firefox, and Edge — no extensions required.

Set Your PIN

Choose a 4 or 6-digit PIN. GoVault derives an AES-256 encryption key from it using PBKDF2 + 200,000 iterations. The PIN is never stored anywhere.

Add Financial Data

Log transactions, bank accounts, cards, passwords, and documents. Every write is encrypted before it touches localStorage.

Back Up or Sync

Export an encrypted backup to a file, or enable optional E2E encrypted cloud sync to keep multiple devices in sync — your PIN never leaves your device either way.
