Security Architecture

Security isn't a feature.
It's the foundation.

Most finance apps can read your data. We literally cannot. Our zero-knowledge architecture means your financial information is encrypted before it ever leaves your device. Even if our servers were breached, attackers would find nothing but meaningless noise.

Client-Side Encryption

Data encrypted in your browser using AES-256-GCM before transmission

Zero-Knowledge Proof

We never see your password or decryption keys — mathematically impossible

Audited Security

Professionally audited encryption. Your data stays yours.

STEP 01

You Enter Data

Expense details typed in your browser

Local Encryption

AES-256 encryption using your password-derived key

STEP 03

STEP 04

Your Eyes Only

Testimonials

Loved by privacy advocates
worldwide.

Finally, an expense tracker that doesn't sell my data. The encryption is real — I verified it myself by inspecting the network requests. This is exactly what I've been looking for.

As a journalist covering sensitive topics, financial privacy is crucial. VaultExpense is the only tool I trust with my expense data. The zero-knowledge architecture means even if they wanted to, they couldn't see my data.

I've audited the encryption implementation. AES-256-GCM with PBKDF2 key derivation — this team knows what they're doing. The security is legit.

FAQ

Frequently asked questions.

Everything you need to know about VaultExpense and our security model.

Your data is encrypted on your device using a key derived from your password before being sent to our servers. We never receive your password or encryption key, making it mathematically impossible for us (or anyone who breaches our servers) to read your data.

Because we use true zero-knowledge encryption, we cannot recover your password or data. We strongly recommend using a password manager and enabling our recovery key feature, which lets you generate a backup key stored securely offline.

Yes! You can invite family members to shared workspaces. Each member has their own password, and we use public-key cryptography to securely share the workspace encryption key without ever exposing it to our servers.

Yes, VaultExpense is currently in free beta with all features included. We believe financial privacy should be accessible to everyone. Early adopters will receive special benefits when we launch paid plans.

We collect only the minimum data needed to operate: your email (for account recovery), encrypted blobs of your financial data, and basic usage analytics. We never see your actual expenses, amounts, or categories.

Absolutely. All users can export their data in CSV or JSON format at any time. Your data belongs to you, and we make it easy to take it with you.
