Welcome to FastCalcy (accessible at https://fastcalcy.com). Your privacy is of paramount importance to us. This Privacy Policy details the types of personal and non-personal data collected, recorded, and utilized by FastCalcy, and explains how we protect your rights in accordance with the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and Google Publisher Policies.
1. Client-Side Calculation Processing (Zero Data Storage)
FastCalcy is engineered as a zero-bloat, client-side utility suite. All mathematical computations—including home loan amortization, mortgage payments, personal income, body mass index, and caloric requirements—are executed locally within your web browser using client-side JavaScript. We do not capture, record, transmit, or store your private numerical figures, salaries, debts, or health metrics on our servers.
2. Google AdSense & Third-Party Advertising
We partner with third-party advertising vendors, including Google AdSense, to serve advertisements when you visit our website. These companies may use cookies, web beacons, and similar tracking technologies to display ads based on your prior visits to FastCalcy and other sites on the Internet.
- Cookies: Google and its partners use cookies and advertising identifiers to serve and measure ads. You can learn how Google uses data from sites that use its services at partner-sites
- Opting Out of Personalized Advertising: You may opt out of the use of DART cookies and personalized advertising at any time by visiting the official Google Ads Settings.
- Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting the Network Advertising Initiative (NAI) Consumer Opt-Out or Digital Advertising Alliance (DAA).
3. Log Files & Web Analytics
Like standard web server infrastructures, FastCalcy logs non-personally identifiable diagnostic data in server log files. This information includes your Internet Protocol (IP) address, browser user-agent, operating system, referring/exit pages, date/time stamps, and pages accessed. This data is used solely to analyze performance trends, prevent security abuse, and optimize Core Web Vitals speed.

If you reside within the European Economic Area (EEA) or the United Kingdom, you have specific data protection rights under the GDPR, including:
- The right to access, update, or delete the information we have on you.
- The right to rectification if information is inaccurate or incomplete.
- The right to object to or restrict processing of your personal information.
- The right to data portability.
5. CCPA Privacy Rights (Do Not Sell My Personal Information)
Under the California Consumer Privacy Act (CCPA), California consumers have the right to request disclosure of the categories and specific pieces of personal data collected, request deletion of collected personal data, and demand that a business does not sell their personal data. FastCalcy does not sell, trade, or monetize personal information.
6. Children's Online Privacy Protection (COPPA)
Protecting children's privacy online is especially critical. FastCalcy does not knowingly collect any personally identifiable information from children under the age of 13.
