Terms of use
By using NETbudget, you agree to the following terms. Please read them carefully.
Purpose of the app
NETbudget is a personal budgeting estimation tool. The calculations provided (social charges, cost-of-living index, 50/30/20 advice) are informational and indicative. They do not replace the advice of a professional (financial advisor, accountant, tax expert).
Liability
The publisher cannot be held responsible for financial decisions made based on the information displayed. Contribution rates per status are estimates derived from public sources (service-public.fr, urssaf.fr); your actual payslip may differ.
Intellectual property
The NETbudget name, logo, interface and source code remain the property of the publisher. The 50/30/20 rule is derived from the work of Elizabeth Warren and Amelia Warren Tyagi, freely available in their books.
Changes to these terms
These terms may be updated. The last update date is shown at the bottom of the page. Continued use of the app after an update constitutes acceptance.
