Best Privacy-Focused Budget Apps 2026

Every mainstream budgeting app requires giving a data aggregator (Plaid, TrueLayer) read access to your bank accounts. These options don't.

Actual Budget

Open-source · Local-first · Free self-hosted, $4/mo cloud

Zero-based budgeting (YNAB-inspired), local SQLite storage, optional self-hosted sync. No data leaves your device unless you opt into their cloud. Active development as of 2026. Best for privacy-conscious YNAB users.

Firefly III

Open-source · Self-hosted · Free

Double-entry accounting, Docker-deployable, full API, webhooks. Used by developers and finance power-users. No cloud component — your data stays on your server. Requires technical setup.

Beancount

Open-source · Plain-text · Free

Plain-text double-entry accounting. Data is a text file on your computer. No network connection, no aggregator, no cloud. Python ecosystem for reporting. For developers and accountants only.

Privacy note on mainstream apps: apps using Plaid store your bank credentials encrypted on Plaid's servers. Plaid is SOC 2 Type II certified and does not sell transaction data. The privacy risk is aggregator breach, not aggregator monetisation. If that risk is acceptable, mainstream apps are functionally private. If not, self-hosted is the correct path.
