Information We Collect
FCalculator.com is designed to offer calculation tools without requiring user registration or the submission of personal identifiable information (PII). We do not collect or store any personal data from the inputs you provide in our calculators, such as financial figures in the Mortgage Calculator or health metrics in the BMI Calculator. All computations are performed client-side within your browser, ensuring that sensitive details remain on your device and are not transmitted to our servers.
However, like many websites, we may automatically collect certain non-personal information through standard web technologies. This includes:
- Log Data: Details such as your IP address, browser type, operating system, referring pages, and timestamps of visits. This helps us analyze trends and improve site performance.
- Cookies and Similar Technologies: We use cookies to enhance user experience, remember preferences (e.g., currency selection in financial tools), and track site usage via analytics services. Cookies are small text files stored on your device. You can manage cookie preferences through your browser settings.
- Usage Data: Aggregated information on how users interact with our tools, such as popular calculators like the Compound Interest Growth Calculator or the Pythagorean Theorem Calculator, to refine our offerings.
We do not link this non-personal data to any individual user. For more on managing cookies, refer to resources from authoritative bodies like the Federal Trade Commission (FTC) on data protection.
How We Use Collected Information
The limited information we gather is used solely to operate, maintain, and improve FCalculator.com. Specifically:
- To provide and optimize our calculation services, ensuring tools like the Auto Loan Calculator or TDEE Calculator function efficiently across devices.
- To analyze site traffic and user behavior anonymously, helping us identify areas for enhancement, such as adding more detailed amortization schedules in loan-related tools.
- To prevent fraud and ensure the security of our platform, protecting against unauthorized access or misuse.
- For internal research purposes, such as understanding global usage patterns in tools like the World Population Calculator without identifying users.
We do not sell, rent, or share any user data with third parties for marketing purposes. Any analytics tools we employ, such as Google Analytics, are configured to respect user privacy settings and comply with data protection regulations.
If you choose to contact us via our Contact Us page, we may temporarily retain provided details (e.g., email address) solely to respond to your inquiry. This information is deleted after resolution and not used for any other purpose.
