Privacy Policy

Last updated: October 30, 2026

CalcSun ("we", "us", or "our") operates this website. This page explains what information we collect, how we use it, and the choices you have. By using this site you agree to this policy.

Information We Collect

We do not require registration and do not collect names, email addresses or other personal identity information to use our tools. The values you enter into calculators and converters are processed to produce your result and are not linked to your identity.

Like most websites, we automatically receive standard technical information when you visit, including your IP address, browser type, device type, referring pages and the pages you visit. This information is used in aggregate to understand how the site is used and to improve it.

Cookies

Cookies are small text files stored by your browser. We use cookies for:

• Essential operation — session cookies required for the website to function.
• Analytics — understanding aggregate traffic and usage patterns.
• Advertising — serving and measuring ads (see below).

You can instruct your browser to refuse cookies or to indicate when a cookie is being sent. Some features may not function properly without cookies.

Advertising

We use Google AdSense to display advertisements on this site. Google, as a third-party vendor, uses cookies (including the DoubleClick cookie) to serve ads based on your prior visits to this and other websites.

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to you 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, or opt out of some third-party vendors' use of cookies at www.aboutads.info.

Analytics

We may use analytics services (such as Google Analytics) to collect anonymous, aggregate statistics about site usage. These services may use cookies and collect your IP address, browser information and pages visited. The data is used solely to understand and improve how the site is used.

Data Sharing

We do not sell, trade or rent your personal information. Aggregate technical data may be processed by the third-party advertising and analytics providers described above, under their own privacy policies.

Data Accuracy Disclaimer

Our tools (including currency exchange rates, size charts and calculators) provide results for informational purposes only and should not be relied upon as professional, financial, medical or legal advice.

Children's Privacy

This site is not directed at children under 13, and we do not knowingly collect personal information from children under 13.

Your Rights (GDPR / CCPA)

Depending on your location, you may have rights to access, correct or delete personal data, to object to processing, and to data portability. Since we collect virtually no personal data, most requests concern the third-party cookies described above — you can manage these directly through your browser settings and the opt-out links in the Advertising section.

Changes to This Policy

We may update this policy from time to time. Changes are posted on this page with an updated revision date.
