Privacy Policy
Last Updated: September 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 using client-side JavaScript. 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. Google AdSense & Third-Party Advertising
CalcNest is a free resource supported by non-intrusive online advertising through Google AdSense and authorized third-party advertising partners.
- Cookies & Web Beacons: Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to our website or other websites on the Internet.
- Google's Use of Advertising Cookies: Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to CalcNest and/or other sites on the Internet.
- Opting Out of Personalized Advertising: Users may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, users can opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info.
3. Analytics & 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. It contains no personally identifiable or calculation data.
4. User Rights (GDPR & CCPA/CPRA)
Because CalcNest does not collect, process, or store personal user accounts or calculator inputs, we do not maintain personal user profiles. If you have questions regarding your data privacy rights under GDPR or the California Consumer Privacy Act (CCPA), you can contact us at any time.
5. 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.
