Privacy Policy.

Last updated: October 2026

At financialcalculatorapp.com, we value your privacy. This Privacy Policy describes how we collect, use, and process your information when you use our suite of web-based financial calculators.

1. Information We Collect & Client-Side Execution

We do not collect any personally identifiable information (PII). All calculations are executed entirely inside your local web browser using JavaScript. No transaction values, financial profiles, incomes, investments, or debts are ever transmitted to our servers or stored by us.

2. Local Web Storage

We use local browser storage (such as localStorage) strictly to save your preferences on your own device, such as your selected currency and dark/light color mode configuration. This data never leaves your device.

3. Google AdSense & Advertising Cookies

We may partner with third-party advertising networks, including Google AdSense, to display ads when you visit our website. Google and its certified partners use cookies to serve ads based on your prior visits to financialcalculatorapp.com or other websites across the Internet.

Google's use of advertising cookies enables it and its partners to serve personalized ads based on your visits to our site and other destinations online. You may opt out of personalized advertising at any time by visiting Google Ads Settings (https://www.google.com/settings/ads) or through the Digital Advertising Alliance / AboutAds consumer choice page (https://www.aboutads.info/choices/).

4. Privacy-First Analytics & CDN Infrastructure

We may load design assets and static scripts from public content delivery networks (CDNs) to maximize global loading speed. We may also review aggregated, anonymized web traffic metrics (such as page view counts and browser types). These metrics never record individual identities, passwords, or personal financial inputs.
