Privacy Policy

Last updated: August 2026

1. Data Minimization & Protection

Numvax values user privacy. All mathematical computations occur strictly in your web browser. We do not store, track, or log the personal numerical figures (e.g. loan amounts, DOB, weight figures) that you enter into calculator forms.

2. Cookies, Analytics & Google Consent Mode v2

Numvax uses Google Analytics 4 (GA4) to understand website traffic, aggregate user interaction trends, and optimize our tools. We also display compliant advertisements via Google AdSense to keep our services free.

We implement **Google Consent Mode v2**, meaning third-party analytics and advertising cookies are **denied by default** for visitors. They are only loaded and run if you explicitly consent to them via our Consent Banner. The consent parameters we respect are:

• analytics_storage: Controls analytics cookie storage.
• ad_storage: Controls advertising-related cookie storage.
• ad_user_data: Controls whether user data is sent to Google for ads measurement.
• ad_personalization: Controls personalized ad remarketing.

You can change or revoke your cookie consent selections at any time by clicking the Cookie Settings link in our website footer.

3. Local Storage Usage

Numvax uses browser local storage (`localStorage`) solely for user convenience to save recent calculations, favorite tools, and cookie consent preferences locally on your device.
