Terms of use

Version of November 1, 2026
Translation of the Spanish version, which prevails in case of discrepancy, unless a provision more favourable to the consumer applies.

These terms govern the use of the seadromy.com website and the Seadromy app (the "service"), published by the person identified in the legal notice. By creating an account or using the service, you accept them. If you do not accept them, do not use the service.

What Seadromy does

Seadromy offers cruising itineraries, passage routes, port and anchorage sheets, and a reading of weather and marine forecasts. These results are calculated automatically from third-party data (numerical forecasts, bathymetry, collaborative mapping, information published about places) and from general rules of prudence. They are proposals for preparing and comparing options. They never describe with certainty the conditions you will meet.

Essential warnings

Not a navigation instrument. Seadromy is not an official nautical chart, an ECDIS or a certified navigation aid. Never use it as your only means of fixing your position or navigating.
The weather is a forecast, not a certainty. Forecasts come from numerical models that get things wrong, disagree with one another and become less reliable the further ahead they look; beyond a few days, they are only indicative. Local phenomena (gusts, thunderstorms, cape or valley winds, rissaga) may not appear in them. Seadromy is not an official weather service. Before every departure and while under way, check the official bulletins (AEMET, Météo-France and the other national services, VHF and NAVTEX bulletins) and observe the actual conditions.
Seabeds, depths and shelter are estimates. Depths, type of seabed, quality of shelter, swell at anchor, distances and times are estimated from data of limited resolution, sometimes old or incomplete. Shoals, rocks, wrecks, buoys, moorings and other obstructions may be missing. Always check against the up-to-date official nautical chart, the sailing directions and the notices to mariners, with the echo sounder and by eye.
Information about places may be wrong or out of date. Facilities, regulations, protected areas, posidonia, mandatory buoys, bathing areas, services and prices change. The authorities and the rules posted on site always take precedence.
The engine's choices are proposals. The itinerary, the order of stops, departure times, overnight anchorages, ports of refuge and fallback options are chosen by an algorithm that knows neither your actual boat, nor your crew, nor its experience, nor the condition of the equipment, nor what you see on the water. A proposed route may turn out to be unsuitable or dangerous on the day.
Navigation mode does not replace keeping watch. The position comes from your device's GPS, which may be inaccurate, lose its signal or run out of battery. The service does not detect other boats or obstructions, it is neither a collision-avoidance system nor an autopilot, and no alarm is guaranteed.
The boat data are estimates. Speeds, polars and fuel consumption are approximations: the passage times and fuel figures given are indicative.

The skipper's responsibility

The skipper remains the sole judge of, and solely responsible for, the decision whether or not to sail, the route followed, the choice of an anchorage or a port, keeping watch, the safety of the boat and of the people on board, and compliance with the applicable rules: the International Regulations for Preventing Collisions at Sea, local and protected-area regulations, safety equipment, boating licences and certificates, insurance. You undertake to have the required skills, licences and equipment, and to check every piece of information against official sources before relying on it. The service is designed for recreational boating; it is not intended for professional or commercial navigation, nor for carrying passengers.

Your account

The service is reserved for adults. The account is personal: you provide a valid email address and protect access to your account. You can delete it at any time by writing to the publisher (show the address); any unused credits are then lost, except as provided for withdrawal in the terms of sale.

Your content

You remain the owner of what you enter in the service (boats, written wishes, observations). You grant the publisher a free, non-exclusive, worldwide licence to use it in order to provide and improve the service. If you send us a correction or an observation about a place (depth, seabed, shelter, rules, photo), you authorise the publisher to incorporate it permanently into the places database. You warrant that you have the right to provide this content and that it does not infringe the rights of third parties.

Permitted use

The publisher's ownership of the service and its database is described in the legal notice. You undertake not to extract the service's data systematically or by automated means, in particular the anchorage data, nor to copy, publish or resell them; not to use them to feed another service or an artificial intelligence system; not to circumvent its technical or payment limits; not to share your account; and not to use it in a way that disrupts its operation or breaks the law. The publisher may suspend or close an account that breaches these terms, after a warning except in an emergency.

Changes to the service and availability

The service is provided as is and as available. It may change: the publisher may add, modify or withdraw features and change, for the future, the number of credits a calculation costs, which is always shown before you start it. It depends on third-party providers (forecasts, maps, hosting, payment) and may be interrupted or limited, in particular for maintenance. At sea, there may be no connection: never rely on the service to get information at the moment you need it. If the publisher closes the service permanently, it will give you at least thirty days' notice and refund the purchased credits you have not used.

The publisher's liability

The publisher takes reasonable steps to provide a quality service, without guaranteeing the accuracy, completeness or timeliness of the results. To the fullest extent permitted by law, the publisher is not liable for damage resulting from navigation decisions, from use of the results without checking them, from weather or sea conditions, from the state of the seabed, from third-party information, from a failure of the device or the connection, from force majeure or from the service being unavailable, and its total liability is limited to the amount you paid it in the twelve months preceding the event giving rise to liability. These limits do not apply in the event of wilful misconduct or gross negligence, to personal injury where the law forbids limiting it, or to the rights that the law grants to consumers and that cannot be excluded.

Purchases

The purchase of credits is governed by the terms of sale.

Changes

These terms may change. The version in force is dated at the top of the page; in the event of a significant change, it is presented to you again in the app for acceptance.

General provisions

If a clause is declared void, the others continue to apply. The publisher's failure to enforce a right does not constitute a waiver of it. Communications relating to your account are sent to your email address.

Governing law and disputes

These terms are governed by Spanish law. If you are a consumer, you keep the protection of the mandatory rules of your country of residence and may bring proceedings before the courts of your place of residence. Before taking any action, write to the publisher (show the address): we will first look for an amicable solution.
