Privacy Policy

This Privacy Policy explains how CalculatorCamp (“we”, “us”, or “our”) handles information when you use our website and calculators. We aim to keep the experience free and useful while being transparent about data practices.

1. Information we collect

Calculator inputs. Values you enter into calculators are processed in your browser session to produce results. We do not require an account to use the tools.

Contact messages. If you use the Contact page, we receive the name, email, subject, and message you submit so we can respond.

Technical logs. Like most websites, our hosting provider may automatically receive standard server logs such as IP address, browser type, referring pages, and timestamps for security and reliability.

2. How we use information

• To operate and improve CalculatorCamp
• To respond to contact requests
• To protect against abuse and technical issues
• To understand aggregate traffic patterns (if analytics are enabled)

3. Cookies & similar technologies

We use essential cookies required for the site to function (for example, security/CSRF protection and one-time status messages). These do not track you across sites.

If analytics are enabled, we use privacy-respecting, aggregated measurement (such as Google Analytics with IP anonymisation or Cloudflare Web Analytics) to understand which tools are used and how pages perform. We do not sell personal information.

4. Advertising (Google AdSense)

CalculatorCamp displays advertisements served by Google AdSense to keep the calculators free. Third-party vendors, including Google, use cookies and similar technologies 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 visit to this site and/or other sites on the Internet.
• You may opt out of personalised advertising by visiting Google Ads Settings, or opt out of some third-party vendors’ cookies at www.aboutads.info.
• Learn how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites.
• Visitors in the European Economic Area, the United Kingdom, and Switzerland are shown a consent message before any personalised advertising cookies are set, and can change their choice at any time.

5. Third-party services

We use trusted providers for hosting and content delivery (Cloudflare and our origin host), web fonts (Google Fonts), and advertising (Google AdSense). Those providers process data under their own privacy policies. Cloudflare may process IP addresses and request metadata to deliver pages securely and to block abusive traffic.

6. Children’s privacy

CalculatorCamp is a general-audience education and utility site. We do not knowingly collect personal information from children under 13. If you believe a child has submitted personal data through our Contact form, please contact us so we can delete it.

7. Data retention

Contact messages are retained as long as needed to respond and maintain records. Server logs are kept according to our host’s standard retention practices.

8. Your choices & rights

• You can use calculators without creating an account
• You can control or delete cookies via your browser settings
• You can opt out of personalised ads via Google Ads Settings where applicable
• Depending on where you live (for example under GDPR or CCPA/CPRA), you may have rights to access, correct, or delete personal data we hold about you — contact us to exercise them
• You can contact us to ask about a message you sent

9. Changes to this policy

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 changes means you accept the updated policy.
