Your data stays yours.

We use bank-level security and a privacy-first approach so you can plan your finances with peace of mind. Here are our key data protection measures.

  • Bank-level Security

    We protect your data with AES-256 encryption and TLS 1.3 protocol — the same standards used by the world's leading financial institutions.

  • End-to-end Encryption

    Your sensitive data is encrypted before it ever leaves your device. Even we cannot read it without your unique access key.

  • We don't sell your data

    Your information is never shared or sold to third parties. Privacy is our top priority, not a commodity.

  • No access to card numbers

    We never ask for or store your full credit card numbers. Your financial privacy remains under your complete control.

How it works, technically

Local IndexedDB storage
Your cards, balances, and payment history are stored in your browser's IndexedDB — a persistent local database that doesn't leave your device.
AES-GCM encryption
Before data is written to IndexedDB, it's encrypted using the Web Crypto API's AES-256-GCM — the same algorithm used by banks and government systems.
Content Security Policy
Strict CSP headers prevent cross-site scripting attacks and block any unauthorized third-party script from loading.
Dependency audits
Every dependency is audited on every CI build. We run automated security scans and review all third-party packages before including them.
Pro sync (encrypted blobs only)
If you use Pro cross-device sync, your data is encrypted client-side before leaving your device. Our servers store encrypted blobs they cannot read.
Export warnings
Before any export containing financial data, we display a clear warning and require explicit confirmation.
