Privacy policy

CalculatorNestX (“we”, “us”, or “our”) provides free online calculators and educational content. This Privacy Policy explains what information we collect, how we use it, and the choices you have — including disclosures related to advertising and analytics partners such as Google.

1. Information we collect

• Calculator inputs you enter. Values you type into calculators are processed in your browser session and on our servers to return results. We do not require an account to use most calculators.
• Contact and feedback forms. If you contact us, suggest a calculator, report an issue, or suggest an improvement, we collect the name, email, and message details you submit.
• Account data (optional). If you create an account, we store your email, display name, and authentication credentials needed to sign in.
• Technical and usage data. Like most websites, we may receive IP address, browser type, device type, referring URL, pages viewed, and approximate location derived from IP. Some of this is collected through cookies or similar technologies.

2. How we use information

• Operate, secure, and improve calculators and site performance
• Respond to contact, suggestion, and issue reports
• Measure traffic and content usefulness (for example with Google Analytics, when enabled)
• Show advertising (for example with Google AdSense, when enabled) and measure ad performance
• Comply with legal obligations and enforce our Terms of Use

3. Cookies and similar technologies

We use cookies and similar technologies for:

• Essential / functional: theme preference, session security (CSRF), and consent choices
• Analytics: understanding how visitors use the site (for example Google Analytics)
• Advertising: delivering and measuring ads (for example Google AdSense and Google advertising cookies)

You can manage non-essential cookies through our on-site cookie preferences banner and through your browser settings. Blocking some cookies may limit analytics or personalized advertising.

4. Advertising (Google AdSense and partners)

When advertising is enabled on CalculatorNestX, third parties — including Google — may use cookies, web beacons, or similar technologies to collect information about your visits to this and other websites in order to provide advertising about goods and services of interest to you (personalized ads), or to serve non-personalized ads where required or requested.

• Google’s use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the Internet.
• You may opt out of personalized advertising by visiting Google Ads Settings and, for many companies, the Digital Advertising Alliance opt-out or Your Online Choices (EU).
• Learn more in Google’s Advertising Technologies and Google Privacy Policy.

For visitors in the European Economic Area (EEA), the United Kingdom, and Switzerland, where required we obtain consent for personalized advertising through a Google-certified consent management experience (configured in Google AdSense Privacy & messaging) and/or our site consent controls before enabling personalized ads or non-essential advertising cookies.

5. Analytics

If Google Analytics (or similar) is enabled, it helps us understand aggregate usage. Analytics may use cookies and collect technical data described above. Where consent is required, analytics that is not strictly necessary will load only after you accept analytics or advertising cookies.

6. Legal bases (EEA/UK where applicable)

Where GDPR or UK GDPR applies, we rely on:

• Consent — for non-essential cookies, analytics (where consent-based), and personalized ads
• Legitimate interests — to operate and secure the site, prevent abuse, and improve calculators
• Contract / steps prior to contract — when you create an account or request support
• Legal obligation — when we must retain or disclose information by law

7. Sharing of information

We do not sell your personal information. We may share data with:

• Service providers that host the website, send email, or process forms
• Advertising and analytics partners such as Google, as described above
• Authorities when required by law or to protect rights, safety, and security

8. Retention

Form submissions and account records are kept as long as needed to respond to you, operate the service, resolve disputes, and meet legal requirements. Analytics and advertising partners apply their own retention rules.

9. Children

CalculatorNestX is intended for a general audience. We do not knowingly collect personal information from children under 13 (or under the age required by local law). Account holders should be 18 or older; a parent or guardian must hold any account for a minor where an account is used.

10. Your choices and rights

Depending on your location, you may have rights to access, correct, delete, or restrict processing of personal data, or to withdraw consent. To exercise these rights, contact us using the details below. You may also lodge a complaint with your local data protection authority.

11. International transfers

Our hosting and partners may process data in countries other than your own. Where required, we rely on appropriate safeguards offered by those providers (such as standard contractual clauses).

12. Changes

We may update this Privacy Policy from time to time. The “Last updated” date at the top will change when we do. Continued use of the site after updates means you acknowledge the revised policy.
