Privacy by default

Without an account, your data stays on your phone

NETbudget works entirely offline: no account to create, none of your finances on a server, no trackers. The only connection fetches exchange rates. If you subscribe, syncing becomes possible — and you decide what gets stored.

Frequently asked questions

What people ask us most

Short, straight answers — including when the answer is not in our favour.

Is it really free?

Yes. The full budget — income, expenses, loans, disposable income, the 50/30/20 rule, the converter — is free with no time limit. An optional subscription adds syncing across devices, shared budgets and tailored advice. No advertising, ever.

Do I need an account?

No, and that is a design choice. You can install the app and use it without ever giving an email address. An account only becomes useful if you want your data on another device or want to share a budget with someone.

Where is my financial data stored?

Without an account, only in your phone's storage: nothing is sent. With an account, whatever you choose to save is synchronised, and end-to-end encrypted by default: the key stays on your phone, so we cannot read your data. Twelve words, viewable from your profile, let you recover that access on another device.

Does it work without internet?

Entirely, apart from two things: the converter's exchange rates, which need fetching once and are then cached, and syncing if you have an account. Your budget calculation itself depends on no server.

Does it work in my country?

The budget and converter work everywhere, in eight languages and with the major currencies. The advice depends on local law: France is covered in depth, while Belgium, Switzerland, Luxembourg, Canada, Spain, Portugal, Italy, Germany, the United Kingdom and several African countries are covered in part.

"You may say to yourself, 'My power and the strength of my hands have produced this wealth for me.' But remember the LORD your God, for it is he who gives you the ability to produce wealth, and so confirms his covenant, which he swore to your ancestors, as it is today."
Deuteronomy 8 : 17-18
