savvy navvy Chartlet Terms of Use.

We know you don’t like reading small legal print, but there are some things we must tell you and others to which you must agree. We’ve tried to be brief - here goes:

Accepting the terms

This bit is easy: by embedding savvy navvy’s Chartlet on your website, you acknowledge you have read and agree with these terms. If you do not agree with these terms, you are not permitted to embed the Chartlet.

We may change these terms of use from time to time to respond to changes in the law, to meet supplier requirements or due to changes in the Chartlet itself. We will of course notify you of any changes in advance.

Please do tell us about anything that concerns you in the terms, as we are always looking for ways to improve.

The service

The savvy navvy Chartlet (“the service”) allows you to bring beautiful savvy charts to your website to indicate a location at sea or on land or share a location or area in an article or blog post.

Our charts and other data sources may change over time. Some parts of the service may occasionally not be available due to circumstances beyond our control. We will be adding to and updating the features, look-and-feel and data content of the service, so expect to see changes! We do our best to test our online service on as many devices and operating systems as is practical, but we cannot guarantee that our service will work on any specific device. If you do encounter problems, please let us know.

Permitted Use

Subject to these terms, you are granted a limited, non-exclusive right to access the service. When accessing the service, you agree to comply with these terms, applicable laws, regulations, and any additional policies or guidelines provided by savvy navvy. The availability of the service, features, or parts thereof may vary, and savvy navvy reserves the right to modify, suspend, or disable access to the service at any time without notice.

You acknowledge that savvy navvy makes no guarantees regarding the accuracy, completeness, or timeliness of location data or any other data displayed by the service. The service is provided on an “as-is” and “as-available” basis.

Our agreement with you is governed by the laws of England and Wales.


We offer the service free of charge until otherwise agreed. As the service grows and our data sources change, we may need to change the amount or structure of our agreement from time to time, including in specific geographical locations. If this happens, we will notify you in advance and seek explicit agreement for any charges. 

Chartlet Activity

To improve our service, we track some activity to analyse how our service is being used. To understand how we use this data, please see our Privacy Policy.

Using The Savvy Chartlet

We grant you permission to use the savvy Chartlet for your personal or business use. You may not make copies, alter, decompile, disassemble or reverse-engineer our software. If you do manage to reverse-engineer our software, drop us a line: if we don’t sue you, we might want to hire you ;-).

You may not remove or obscure any copyright or trademark notices from the service. You may not copy, sell, trade or resell any of the data or services we provide to you. You may not imply affiliation or endorsement. You may not display in specific contexts such as adult content or illegal activities, and any other context we may determine unfit. You may not challenge savvy navvy's brand features or attempt to register features that may cause confusion. 

That’s a pile of ‘may nots’, but the explicit intent is to ensure mutual respect for our brands.

Marketing Licence

Throughout the duration of this agreement, you grant savvy navvy a non-exclusive, global, and royalty-free licence to utilise your brand features and your content for promotional purposes. This may include showcasing your marks in presentations, marketing materials, customer lists, financial reports, website listings (including links to your website), and the creation of marketing or advertising materials featuring screenshots of the service where your content is highlighted. Your cooperation in this regard is greatly appreciated.

Being obnoxious

It is a shame that we still have to say this, but we will not tolerate any discriminatory or otherwise objectionable content to be posted, shared or otherwise made public via the service or on our social media pages. This includes but is not limited to discrimination on the basis of race, national or ethnic origin, age, religion, disability, gender, gender expression or gender preference, as well as harmful, threatening, inflammatory, harassing, vulgar, unlawful, defamatory, infringing, abusive, obscene, fraudulent, or privacy invasive content. savvy navvy will not discriminate against you if you exercise your right to opt out of providing personal information for use in performance management or for resale, or request us to delete your account.  

We retain the right to suspend your use of the Chartlet and remove any content without further notice if we deem it to be unlawful and/or in violation of this agreement.


You have the right to remove the Chartlet from your website any time. We reserve the right to terminate your use of the Chartlet without reason at any given time.

Keeping our Terms of Use up to date

As the savvy navvy service grows and governing laws change from time to time, we will occasionally need to update these terms. We will give you notice via the service or via email so that you can review the new Terms of Use. If they are not acceptable to you, you may remove the Chartlet embed from your website. Continued usage of the service will mean you have accepted the new terms and have agreed to be bound by them.

Copyright licences and acknowledgements

The savvy navvy service uses data from many sources, most of which have asked us to pass on important licence or other information that they want you to know. We keep that information here: Third Party notices. The sources and the text will change from time to time. Please read it carefully.
