Ocean Efficiency ("the Service") provides planning tools for commercial maritime use, including geopolitical boundary overlays, sunrise/sunset timing, tidal data visualisation, route and rest-hour calculators, and voyage efficiency analysis. The Service is intended solely to assist mariners in making non-safety-critical commercial planning decisions and is provided by Tom Shelley ("the Operator").
This Service must not be used as a primary or sole source for navigation, route approval, collision avoidance, or regulatory compliance. Users must consult official, flag-state-approved publications (e.g. Admiralty charts, Total Tide, Notices to Mariners) and reputable commercial or governmental services for all voyage-critical and safety-of-life decisions. No output of this Service replaces the professional judgement of a qualified deck officer or pilot.
The Service and all data, calculations, and outputs are provided "AS IS" and "AS AVAILABLE" without warranty of any kind, whether express, implied, or statutory. To the fullest extent permitted by applicable law, the Operator disclaims all warranties, including but not limited to implied warranties of merchantability, fitness for a particular purpose, accuracy, completeness, timeliness, and non-infringement. No information or advice, whether oral or written, obtained from the Service shall create any warranty not expressly stated herein.
To the maximum extent permitted by law, in no event shall the Operator, its affiliates, data providers, or any third-party service providers be liable for any direct, indirect, incidental, special, consequential, or punitive damages, including but not limited to: loss of life or personal injury arising from navigational reliance; grounding, collision, or any maritime incident; commercial losses, lost profits, or business interruption; loss of data; or any other damages arising out of or in connection with the use of, inability to use, or reliance upon the Service or its outputs, regardless of the theory of liability (contract, tort, strict liability, or otherwise), even if the Operator has been advised of the possibility of such damages.
If, notwithstanding the foregoing, the Operator is found liable, total aggregate liability shall not exceed the greater of (a) the fees actually paid by you for the Service in the twelve (12) months preceding the claim, or (b) fifty pounds sterling (£50).
You agree to indemnify, defend, and hold harmless the Operator and its affiliates from and against any claims, liabilities, damages, losses, costs, or expenses (including reasonable legal fees) arising out of or related to: (a) your use or misuse of the Service; (b) any navigational, operational, or commercial decision made in reliance on the Service; (c) your breach of these Terms; or (d) your violation of any applicable law or regulation.
You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. You must notify us immediately at [email protected] if you become aware of any unauthorised use. The Operator is not liable for any loss arising from unauthorised access to your account.

The Operator reserves the right to modify, suspend, or discontinue the Service (or any part thereof) at any time without notice or liability. These Terms may be updated from time to time; the "Effective Date" above will reflect the most recent revision. Continued use of the Service after changes constitutes acceptance of the revised Terms. It is your responsibility to review these Terms periodically.
Access may be suspended or revoked at any time at the Operator's sole discretion, including for abuse, misuse, or non-compliance with these Terms. Upon termination, your right to use the Service ceases immediately. Sections 3, 5, 6, 7, and 15 survive termination.
These Terms shall be governed by and construed in accordance with the laws of England and Wales. Any dispute arising out of or in connection with these Terms shall be subject to the exclusive jurisdiction of the courts of England and Wales. Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for death or personal injury caused by negligence or for fraud.
If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions shall continue in full force and effect. These Terms, together with any documents expressly referred to herein, constitute the entire agreement between you and the Operator regarding the Service, and supersede all prior agreements, understandings, or representations.
