Privacy Policy
Last Updated: August 2026
Our Core Privacy Commitment
Your calculator inputs never leave your device. When you type loan amounts, interest rates, birthdays, or body weights into CalcNest, all math operations execute strictly within your local web browser. We do not store, log, or transmit your calculation data to our servers or any third parties.
1. Information We Do Not Collect
We do not require user registration, account creation, or login. We do not collect or store:
- Financial figures, loan amounts, salaries, or investment projections.
- Dates of birth, age queries, or calendar schedules.
- Health metrics such as height, weight, or calculated BMI values.
- Personally Identifiable Information (PII) like names, phone numbers, or passwords.
2. Zero Advertisements & Zero Tracking Cookies
CalcNest is completely ad-free. We do not display third-party advertisements, do not run advertising networks, and do not use advertising cookies, marketing pixels, or third-party tracking scripts.
3. Server Log Data
Like all web servers, our static hosting server (Caddy / Ubuntu VPS) automatically records standard web request data, including your IP address, browser type, referring/exit pages, and timestamps. This data is used exclusively for server diagnostics, security monitoring, and maintaining uptime.
4. Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect site improvements or regulatory changes. Any modifications will be posted on this page with an updated timestamp.
