The Big Picture
We are committed to the privacy of our visitors. We collect no personal information about you when you visit our website unless you choose to provide that information to us.
Here is how we handle information about your visit. When you browse through this website, read pages, or download information, we will gather and store certain information about your visit automatically. This information does not identify you personally. During your visit, we may automatically collect and store the following:
By learning about the number of visitors to our site and the types of technology our visitors use, we can make our site more useful.
For site security purposes, and to ensure that this service remains available to all users, this government computer system employs software programs to monitor network traffic to identify unauthorized attempts to upload or change information, or otherwise cause damage. If such monitoring reveals evidence of possible abuse or criminal activity, such evidence may be provided to appropriate law enforcement officials. Unauthorized attempts to upload or change information on this server are strictly prohibited and may be punishable under the Computer Fraud and Abuse Act of 1986 and the National Information Infrastructure Protection Act or other law.
We do not collect personally identifiable information unless you choose to provide it to us. If you provide us with personally identifiable information, for example by sending an e-mail or by filling out a form and submitting it through our website, we use that information only to respond to your message and to help us provide you with the information and services you request.
Submitting voluntary information constitutes your consent to the use of the information for the stated purpose. When you click the "Submit" button on any of the Web forms found on our site, you are indicating voluntary consent to use of the information you submit for the stated purpose. We do not collect or use information for commercial marketing.
We use the information we collect for a variety of purposes (e.g., chart corrections, nautical inquiries, survey requests, and to respond to requests for information about our products and policies). We make every effort to disclose clearly how we use information—at the point where it is collected—so you can determine for yourself whether you wish to provide the information.
We may share the information you give us with another government agency if your inquiry relates to that agency. In other limited circumstances, such as responses to requests from Congress and private individuals, we may be required by law to disclose information you submit. Before you submit personally identifiable information, such as on an online form, you will be advised as to the purpose and how the information will be used.
We may also share information collected during your visit with non-federal entities, but only if your inquiry requires accessing data from that external entity. All of our sites that require such external access will be clearly identified to help you make an informed choice.
Specifically, information collected during your visit may be shared with the following specific non-governmental entities:
We destroy the information we collect when the purpose for which it was provided has been fulfilled, unless statute or official policy requires us to keep it longer. Electronically submitted information is maintained and destroyed according to the principles of the Federal Records Act and the regulations and records schedules approved by the National Archives and Records Administration; in some cases information submitted to us may become an agency record and therefore might be subject to a Freedom of Information Act request.
"Cookies" are small bits of text that are either used for the duration of a session ("session cookies"), or saved on a user's hard drive to identify that user, or information about that user, the next time the user logs on to a website ("persistent cookies"). This website does not use persistent cookies or any other persistent tracking technology. However, this site does use Google Analytics, a tool that provides basic information about website visitors. Please note that this third party service will place a file on your computer so that it can recognize if you visit nauticalcharts.noaa.gov in the future. See below for more information. Lastly, one or more of our component sites may use session cookies to provide streamlined navigation. These session cookies are deleted from the component's server after your session ends and information from them is not collected or saved.
This website may offer educational content to children under 13. No personally identifiable information is collected from them unless voluntarily submitted as a request for information or services. We use the collected information to respond to user inquiries or to provide services requested by our users.
The Office of Coast Survey maintains official pages or accounts on several third-party websites to better engage with the American public and promote awareness of Coast Survey activities, events, news, and information (a list of these tools is highlighted below). Your activity on those third-party sites is governed by the security and privacy policies of the third party sites. Users of third-party sites are often sharing information with the public, user community, and/or the third-party operating the third-party site. You should review the privacy policies of third-party sites before using them and ensure that you understand how your information may be used. You should also adjust privacy settings on your account on any third-party site to match your preferences.
This site uses Google Analytics, a third-party web measurement and customization technology as defined and organized by the Office of Management and Budget (OMB), "Guidance for Online Use of Web Measurement and Customization Technologies" (OMB M-10-22). Google Analytics places a small file on your computer, commonly called a "cookie," so that it can recognize your computer if you visit oceanservice.noaa.gov in the future. This cookie does not collect personal identifying information. This is considered a Tier 2 service in the OMB guidance.
Visitors who choose to disable this web measurement will still have full access to oceanservice.noaa.gov. While the details vary from browser to browsers, most modern browsers can be set up to accept, reject, or request user intervention when a site asks to set a cookie.
