CalcNest is a free calculator website. We collect only the minimum information necessary to operate the site and display advertisements.
When you visit CalcNest, our hosting provider and third-party services may automatically collect standard web server log data, including:
This information is used solely for site analytics, security monitoring, and improving the user experience. It is not sold or shared with third parties for marketing purposes.
CalcNest does not require you to create an account, log in, or submit any personal information to use any calculator on the site. We do not have contact forms that collect personal data. If you email us directly, we retain only what is necessary to respond to your inquiry.
When you use a CalcNest calculator, JavaScript running locally in your browser performs the calculation and displays the result. No data leaves your device. Closing your browser tab clears all entered values completely.
We will never ask you to enter personally identifying information such as your Social Security number, bank account details, or government ID into any calculator.
Cookies are small text files stored in your browser. CalcNest itself does not set any first-party cookies. However, third-party services we use — specifically Google AdSense — may set cookies in your browser.
You can control and delete cookies through your browser settings. Most browsers allow you to refuse cookies entirely, accept only certain types, or delete existing cookies. Note that disabling advertising cookies will not remove ads — it will cause less relevant ads to be displayed instead.
You can also opt out of personalised advertising across Google's network by visiting google.com/settings/ads or by using the Digital Advertising Alliance opt-out tool.
CalcNest displays advertisements served by Google AdSense (Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA). Advertising is how we keep all calculators free with no subscription or sign-up required.
Google AdSense uses cookies and web beacons to serve ads based on your prior visits to CalcNest and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other sites on the Internet.
You can opt out of personalised advertising by visiting Google's Ads Settings. For more information on how Google uses data when you use our site, see Google's Privacy & Terms.
CalcNest's publisher ID is ca-pub-3455077068791401. We comply with all Google AdSense programme policies.
CalcNest uses the following third-party services. Each has its own privacy policy that governs how they handle data:
We do not sell, trade, or rent your personal information to any third parties. We do not use any social media tracking pixels, affiliate tracking scripts, or any analytics tools beyond those listed above.
CalcNest does not store any personal data on our servers. Server access logs (IP addresses, page requests) maintained by our hosting provider are typically retained for 30–90 days for security and diagnostic purposes, after which they are automatically deleted.
Any data collected by Google AdSense is governed by Google's own data retention policies, which you can review in their Privacy Policy.
Depending on your location, you may have certain rights regarding your personal data. Since CalcNest collects minimal data, most of these rights are satisfied by design, but we acknowledge them fully:
To exercise any of these rights, contact us at the address in Section 10.
CalcNest is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. Our GPA and education calculators are general-purpose tools suitable for all ages, but they do not collect any personal data from any user regardless of age.
If you believe a child under 13 has provided personal information to us, please contact us immediately and we will take steps to delete that information.
We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. When we make changes, we will update the "Last updated" date at the top of this page.
We encourage you to review this Privacy Policy periodically. Your continued use of CalcNest after any changes constitutes your acceptance of the updated policy. If we make material changes that significantly affect your privacy rights, we will make reasonable efforts to notify users.
If you have any questions, concerns, or requests regarding this Privacy Policy or your personal data, please contact us:
