BizBunker

More than a budget app — for solopreneurs and freelancers.
If your revenue drops to zero this month, how many days does your business survive? BizBunker shows your exact Runway D-Day.
No account, no cloud — AES-256 encrypted, 100% on-device.

BizBunker is an offline business finance command center designed for solo entrepreneurs, freelancers, and small business owners.

It helps you understand your cash runway, manage fixed expenses, simulate cost reductions, visualize client and project dependency, and separate tax reserve funds from usable cash.

All data is stored locally on your device. BizBunker does not require user registration, cloud sync, or a backend server, helping you keep sensitive business information private and under your control.

Key Features:

■ Runway Dashboard
Check how long your business can survive based on current cash, expected income, and fixed expenses.

■ Cost Diet Simulation
Turn expenses on or off and instantly see how reducing costs affects your remaining runway.

■ Dependency Graph
Visualize which clients or projects create financial concentration risk.

■ Tax Bunker
Separate tax reserve funds from usable operating cash to avoid misleading financial assumptions.

■ Time Machine Backup
Create local backup snapshots and restore previous data when needed.

BizBunker helps you make practical financial decisions from a secure, offline workspace.
