These terms apply to your use of surfsizer.com. By using the site you accept them. If you do not, please stop using it — there is nothing to cancel, since there is no account.

What the site is

SurfSizer provides free surf sizing calculators and explanatory guides. It is an information service. It does not sell anything, take payment, hold accounts, or act as an intermediary in any purchase you make elsewhere.

Using the site

You may use the calculators and read the guides freely, for personal or commercial purposes, without asking permission and without payment. You may link to any page here.

You may not: scrape or bulk-download the site in a way that degrades it for others; republish substantial portions of the written content as your own; frame or present the site in a way that implies affiliation or endorsement that does not exist; attempt to interfere with the site's operation or security; or use it for anything unlawful.

The results are estimates

This deserves stating in the terms as well as everywhere else on the site. Every figure produced by a calculator here is an estimate derived from published rules of thumb, not a measurement or a specification. It is intended to inform a decision, not to make one for you.

Nothing on this site is professional, medical or safety advice, and nothing on it tells you whether it is safe to enter the water. The Disclaimer sets out the limits in full and forms part of these terms.

No warranty

The site is provided as is and as available, without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose and non-infringement. No promise is made that the site will be uninterrupted, error-free, or that the information on it is complete or current.

Limitation of liability

To the fullest extent permitted by applicable law, SurfSizer and its owner accept no liability for any direct, indirect, incidental, consequential or special loss or damage arising from your use of, or inability to use, this site or anything on it. That expressly includes decisions made and money spent on equipment on the basis of a figure produced by a calculator here.

Nothing in these terms excludes or limits liability where it would be unlawful to do so, including for death or personal injury caused by negligence, or for fraud.

Intellectual property

The written guides, the calculator logic and the design of this site are the work of its owner and are protected by copyright. You are welcome to quote a short passage with a link back. Reproducing whole pages, or republishing the content as your own, is not permitted.

Brand, manufacturer and product names appearing on the site belong to their respective owners and are used descriptively. SurfSizer is not affiliated with, endorsed by or sponsored by any of them.

Links to other sites

Links to external websites are provided for convenience and reference. Those sites are outside our control, and we are not responsible for their content, their accuracy or how they treat your data. A link is not an endorsement.

Advertising

The site currently carries no advertising. If advertising is introduced, it will be clearly distinguishable from the site's own content and will not be presented as editorial recommendation. Advertisements are supplied by third parties, and their presence is not an endorsement of the advertiser or their products.

Governing law

These terms and any dispute arising out of or in connection with them or with your use of this site are governed by and construed in accordance with the laws of the United States of America, without regard to conflict-of-law principles. You agree that any such dispute will be brought in the courts of the United States.

If any provision of these terms is found to be unenforceable, that provision will be limited or removed to the minimum extent necessary and the remaining provisions will stay in full effect. A failure to enforce any part of these terms is not a waiver of the right to do so later.

Changes

These terms may be revised from time to time; the date at the top shows the last revision. Continued use of the site after a change means you accept the revised terms. The site itself may also change, and pages may be added, altered or withdrawn without notice.
