Last updated: July 7, 2026
Overview
This Cookie Policy explains how Nautical Solver uses cookies, browser storage, analytics tools, advertising services, and similar technologies when you visit or interact with the website.
Nautical Solver is a naval architecture and marine engineering platform that provides informational content, engineering references, and online calculators related to ship design, resistance prediction, propulsion, stability, fuel consumption, and other marine engineering topics.
Cookies and related technologies help the website function properly, remember limited choices, understand general usage trends, improve the calculators and content, and support the platform through advertising revenue.
What are cookies?
Cookies are small text files stored on your device by websites you visit. They are commonly used to enable technical functionality, remember preferences, analyze traffic patterns, and support advertising or measurement systems.
Cookies may include:
- Session cookies — temporary cookies that usually expire when you close your browser.
- Persistent cookies — cookies that remain on your device for a specified period of time.
- First-party cookies — cookies set directly by the website you are visiting.
- Third-party cookies — cookies set by external services integrated into the website, such as analytics or advertising providers.
Cookies do not always directly identify an individual person, but they may be associated with browser identifiers, device information, approximate location data, usage events, or aggregated analytics data depending on the technology involved.
How Nautical Solver uses cookies and related technologies
Nautical Solver aims to keep tracking and data collection limited while still maintaining reliable website functionality and sustainable operation.
Cookies or similar technologies may be used for purposes including:
- Providing basic website functionality and security
- Remembering cookie consent choices
- Remembering limited interface or usability preferences
- Understanding general traffic and usage trends
- Measuring website performance and reliability
- Improving engineering calculators, content, and user experience
- Supporting advertising services used to fund the platform
Nautical Solver itself does not use cookies to directly identify visitors by name, and it does not independently build personal advertising profiles.
Examples of cookies and storage used
The exact cookies and storage items used may vary depending on your location, browser settings, consent choice, device settings, ad blocker settings, and whether analytics or advertising services are active. Examples may include:
| Name / type | Provider | Purpose | Approximate duration |
|---|---|---|---|

_ga, _ga_*, and similar analytics cookies |
Google Analytics | Used for analytics measurement when permitted by consent settings. | Set by Google; duration may vary |
| Google advertising cookies or identifiers | Google AdSense / Google advertising services | Used for ad delivery, ad measurement, fraud prevention, frequency capping, and, where permitted, ad personalization. | Set by Google; duration may vary |
This table is provided as a practical summary. Cookies and storage items may change as website features, analytics settings, advertising settings, browser behavior, or third-party services change.
Analytics services
Nautical Solver uses Google Analytics 4 (GA4) to better understand general website usage patterns, including page visits, traffic sources, device types, approximate geographic regions, and interaction trends.
Google Analytics may use cookies or similar technologies to collect statistical information about website usage. This information helps Nautical Solver understand which calculators and pages are useful, improve site structure, monitor performance, and improve content quality.
Nautical Solver uses Google Consent Mode settings so that analytics and advertising storage choices can be adjusted according to the visitor's consent choice. When optional cookies are declined, analytics may operate in a more limited way.
Nautical Solver also uses privacy-oriented analytics settings where reasonably possible, including IP anonymization and limited advertising personalization settings.
Advertising and Google AdSense
Nautical Solver may display advertisements through Google AdSense or related Google advertising services. Advertising helps support the cost of maintaining and improving the free calculators and engineering content available on the website.
Advertising providers may use cookies, browser identifiers, or similar technologies to:
- Deliver advertisements
- Measure advertisement performance
- Limit repetitive ad displays
- Detect invalid traffic, abuse, or fraud
- Support basic advertising functionality
- Provide regionally appropriate advertisements
- Personalize advertisements where permitted by consent and applicable law
Depending on your location, applicable regulations, browser settings, and consent choices, advertising technologies may be limited, disabled, or used differently.
Google and participating advertising partners may process information according to their own policies, technical systems, and legal obligations.
Consent management
Nautical Solver may present visitors with a cookie consent banner that allows optional analytics and advertising cookies to be allowed or declined.
The consent banner may allow visitors to:
- Allow optional analytics and advertising cookies
- Decline optional analytics and advertising cookies
- Close the notice temporarily
If optional cookies are allowed, Google Analytics and advertising services may operate with consent-enabled storage. If optional cookies are declined, optional cookies are not intentionally enabled by Nautical Solver and related services may operate in a limited mode or may not load.
Where required by applicable law or platform rules, additional consent requirements may apply, including for users in the European Economic Area (EEA), the United Kingdom, Switzerland, or other regulated regions.
Browser storage and local device data
Some Nautical Solver calculators or interface components may use browser
storage technologies such as localStorage, session storage,
or similar local mechanisms.
These technologies may be used for purposes such as:
- Remembering cookie consent choices
- Temporarily retaining calculator inputs
- Improving usability between page reloads
- Supporting interface preferences
- Reducing unnecessary repeated input
In many cases, locally stored information remains on your own device and is not transmitted to Nautical Solver servers unless a specific feature requires transmission.
You may clear browser storage at any time through your browser settings.
Example usage scenario
For example, if a visitor uses a ship resistance calculator multiple times while comparing hull forms or propulsion assumptions, temporary browser storage may help preserve entered values during navigation or page refreshes.
Similarly, analytics systems may record that a calculator page was visited or interacted with. This helps Nautical Solver understand which engineering tools are most useful to visitors overall.
Advertising systems may also record limited technical events, such as ad impressions or invalid traffic signals, depending on consent settings and applicable rules.
Third-party services
Nautical Solver may rely on third-party infrastructure or service providers including, but not limited to:
- Web hosting providers
- Analytics services, including Google Analytics
- Advertising providers, including Google AdSense
- Content delivery, library, or performance services
- Security and traffic protection systems
These providers may use their own cookies or related technologies according to their own privacy policies, cookie policies, technical settings, and legal obligations.
Managing, disabling, or clearing cookies
Most web browsers allow users to manage, block, or delete cookies through browser settings.
Depending on your browser, you may be able to:
- Delete existing cookies
- Clear localStorage and other site data
- Block future cookies
- Disable third-party cookies
- Receive notifications when cookies are set
- Use private browsing or tracking-prevention features
You can change or withdraw your cookie choice by clearing Nautical Solver cookies and site data in your browser settings. After clearing site data, the cookie banner may appear again on your next visit.
Please note that disabling certain cookies or storage mechanisms may affect website functionality, usability, analytics accuracy, advertising availability, or performance.
