1. Who We Are

finance-fast.com is operated by Stromájer László, an individual based in Hungary. For privacy-related questions, contact us at privacy@finance-fast.com.

2. Calculator Data Privacy

All financial data you enter into our calculators — including salary figures, loan amounts, mortgage balances, retirement projections, credit card details, and investment values — is processed entirely within your browser. This data is never transmitted to our servers or to any third party. We have no access to the values you enter, and nothing is stored beyond your current browser session.

3. Data We Collect Automatically

We do not collect your name or email address. The following data is collected automatically when you visit the site:

• Usage data — pages visited, session duration, browser type, operating system, and approximate location (country/region). Collected via Google Analytics 4 (property ID: G-NZLGYL6DBG). Analytics data is only collected after you give consent via the cookie banner. You can opt out at any time using the Google Analytics Opt-out Browser Add-on.
• IP address — transmitted to Google as part of Analytics and advertising requests. Google may use it to approximate geographic location. We do not store IP addresses ourselves.
• Cookies — set by Google Analytics and Google AdSense (publisher ID: ca-pub-6164838820338976). Advertising cookies are only set after you give consent. See our Cookie Policy for the full list and details.

4. Google AdSense and Third-Party Advertising

We display advertisements served by Google AdSense (publisher ID: ca-pub-6164838820338976). Google and its partners may use cookies to show you ads based on your prior visits to this site and other sites. This includes cookies such as IDE and DSID set by Google's DoubleClick ad network. Advertising cookies are only activated after you accept via the cookie banner.

You can opt out of personalised advertising at Google Ad Settings or the NAI opt-out page. For more information on how Google uses data from sites that use its advertising services, see How Google uses information from sites or apps that use our services.

5. Legal Basis for Processing (GDPR Art. 6)

For users in the European Economic Area, our legal basis for processing is:

• Analytics cookies — consent (Art. 6(1)(a)). You can withdraw consent via the cookie banner at any time.
• Advertising cookies — consent (Art. 6(1)(a)). You can withdraw consent via the cookie banner or Google Ad Settings.
• Functional storage (theme preference) — legitimate interest (Art. 6(1)(f)) in providing a consistent user experience. No tracking purpose.

6. Third-Party Services

We use Google Analytics 4 (ID: G-NZLGYL6DBG) and Google AdSense (publisher ID: ca-pub-6164838820338976). Google acts as a data processor under Standard Contractual Clauses approved by the European Commission. Google may transfer data to the United States.

7. Data Retention

We do not store personal data on our own servers. Google Analytics data is retained for 14 months by default, after which Google deletes it automatically. Google AdSense cookie data is retained according to each cookie's duration (see our Cookie Policy for durations). You can request earlier deletion by contacting us at privacy@finance-fast.com.
