Privacy Policy

1) Overview

Nautical Solver respects your privacy. This site is designed to provide browser-based engineering calculators without requiring user accounts, registrations, or direct submission of personal data.

2) Information we do not collect

We do not knowingly collect or store personally identifiable information such as names, addresses, phone numbers, or payment details. The calculators operate entirely on the client side in your web browser.

3) Local storage & calculator inputs

Some calculators may store recent input values in your browser’s localStorage to improve usability (for example, retaining values after a page refresh). This data:

• Remains on your device
• Is not transmitted to Nautical Solver servers
• Can be cleared at any time via your browser settings

4) Cookies

Nautical Solver does not set first-party tracking cookies for profiling users. However, third-party services used on the site may place cookies as part of their normal operation.

5) Advertising

This site may display advertisements provided by Google AdSense. Google and its partners may use cookies or similar technologies to serve ads based on your visits to this and other websites.

Users may opt out of personalized advertising by visiting Google’s Ads Settings or by using browser-level privacy controls.

6) Analytics & third-party services

We may use third-party services such as content delivery networks (CDNs), advertising platforms, or analytics tools to operate and improve the site. These services may collect anonymized technical information such as:

• Browser type and version
• Device type
• Approximate location (country or region)
• Pages visited and interaction timing

Such data is used solely for performance monitoring, usage statistics, and service improvement.

7) Exported files

When you generate or export a PDF or image from a calculator, the file is created locally within your browser and saved directly to your device. Nautical Solver does not receive, store, or process exported files.

8) External links

This site may contain links to external websites. We are not responsible for the privacy practices or content of third-party sites. Users should review the privacy policies of any external services they visit.

9) Children’s Privacy (COPPA)

Nautical Solver is a general-audience technical website intended for students, professionals, and anyone interested in naval architecture and marine engineering. It is not specifically directed at children under the age of 13.

In accordance with the U.S. Children’s Online Privacy Protection Act (COPPA), we do not knowingly collect, store, or request personal information from children under 13 years of age.

The calculators on this site run entirely in the user’s browser and do not require account creation, personal details, or user identification. Children may use the site for educational purposes, but no personal data should be submitted.

If you believe that personal information from a child under 13 has been provided to us unintentionally, please contact us and we will promptly remove such information.
