Your privacy
What the SeaDream II guest Wi-Fi signup and billing system collects, why, and for how long.
Who is responsible
SeaDream Yacht Club Limited operates this system and is responsible for your details under data protection law (the "controller").
What this system uses, and why
Your name and stateroom — typed at signup and matched
against the voyage's guest list, so Wi-Fi charges go to the right
stateroom account and included allowances go to the right guest. If a
match fails, what you typed is kept so the ship can help you.
Basis: providing the service you asked for and billing it.
Your device's network address (MAC) — provided by the
ship's Wi-Fi system; it is how your device is recognised and allowed
online. Basis: our legitimate interest in running a secure, fair
network.
Your email — only if you choose to enter it, and only on
yachts where receipts are emailed, for your receipt. News-and-offers email
is a separate, unticked checkbox and entirely optional.
Basis: your choice (consent) for marketing.
Purchases and adjustments — kept as a billing ledger so
your onboard account is correct and disputes can be resolved.
Basis: billing and bookkeeping duties.
Technical diagnostics — if a page fails, an error report
without your personal details goes to our monitoring service; web server
logs are kept for about two weeks.
What this system doesn't do
We do not sell your details, and this system never emails you marketing
unless you ticked the separate consent box (you can withdraw at any
time). You may still hear from SeaDream Yacht Club if you have shared
your details with us in other ways — for example when booking your
voyage — under SeaDream's general privacy practices, not this notice.
We do not routinely monitor or read the content of your internet
traffic, and nothing records what you see on your screen. Technical
connection records (such as device identifiers, connection times and
data volumes) are used to operate, secure and troubleshoot the service,
as described in the Terms of
Service, which govern how the network is run.
Who else handles it
The system is hosted by DigitalOcean in the United States. Error reports go to Sentry and emails are sent through Postmark, both in the United States. Each works for us under written data-processing terms, including safeguards for information transferred outside the European Economic Area. The ship's Wi-Fi equipment (Ubiquiti) holds your device's network address while it is connected. Nobody else receives your details unless the law requires it.
How long this system keeps things
Wi-Fi purchase records (purchases, credits, receipts, your acceptance of
the terms, and the staff actions taken on them): 24 months
after the voyage, for billing disputes.
Device network addresses: replaced with pseudonymous codes (one-way codes
that cannot be turned back into an address)
90 days after the voyage.
The voyage guest list, and anything you typed at signup: removed
30 days after the voyage (your billing record keeps only
the name and stateroom it was made with).
Marketing consent: until you withdraw it.
Charges posted to your stateroom account also appear in SeaDream's
accounting records, which are kept under SeaDream's own bookkeeping and
legal requirements — those may run longer than the periods above.
Your rights
You can ask to see the details this system holds about you, have them corrected or deleted, restrict or object to their use, receive the details you gave us in a portable form, and withdraw marketing consent at any time. Billing records may be kept for the period above even after a deletion request. You can also complain to a data protection authority.
Questions or requests
On board, speak to the Concierge. After your voyage, contact SeaDream Yacht Club Limited through Guest Services (contact details at seadream.com). Anything the ship can't resolve on the spot is passed to our shore team.
