1. Information We Collect

MarineWireCalc ("we", "us", "our") does not require user registration or account creation. All calculation inputs (such as voltage, amperage, battery capacity, and cable lengths) are processed entirely client-side in your web browser. None of your calculation inputs are transmitted to or stored on our servers.

2. Cookies and Third-Party Advertising (Google AdSense)

We may display advertisements served by third-party advertising partners, including Google AdSense:

• Google, as a third-party vendor, uses cookies to serve ads on our site based on prior visits to our website or other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to our site and/or other sites on the Internet.
• Users may opt out of personalized advertising by visiting Google Ads Settings.

3. Affiliate Disclosure (Amazon Associates)

MarineWireCalc is a participant in the Amazon Services LLC Associates Program and other affiliate advertising programs designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com and affiliated sites. If you click an affiliate link and make a purchase, we may receive a small commission at zero additional cost to you.

4. Web Analytics

We use lightweight, privacy-conscious web analytics tools (such as Cloudflare Web Analytics or Google Analytics 4) to monitor aggregate traffic trends, browser types, and page popularities to improve our calculators. These tools collect anonymized IP data.

5. Your Privacy Rights (GDPR & CCPA)

Depending on your jurisdiction, you may have rights under the General Data Protection Regulation (GDPR) or California Consumer Privacy Act (CCPA) to access, delete, or limit the collection of your personal data. To exercise any data privacy rights, please reach out via our Contact Page.
