Media

Visitors cannot upload images to our website. Any images displayed on the site are provided by us and do not contain embedded location data that we make available for download.

Cookies

We do not offer user accounts or login functionality on our website. If, in the future, we enable login or registration, we will only store related account data if you choose to create an account and log in.

However, we and our service providers may use cookies and similar technologies for:

  • Remembering your search and filter preferences when browsing yachts and destinations.

Embedded content from other websites

Articles on this site may include embedded content (e.g., videos, images, articles, maps, social media posts, booking widgets). Embedded content from other websites behaves in the same way as if you had visited that other website directly.

These websites may collect data about you, use cookies, embed additional third‑party tracking, and monitor your interaction with that embedded content, including tracking your interaction if you have an account and are logged in to that website.

Examples may include YouTube videos, Google Maps, Instagram posts, or third‑party booking or chat tools. Their own privacy policies apply to such interactions.

How we use your personal data

We use your personal data to:

  • Provide, manage, and administer yacht charter bookings and related services (including crew, skippers, provisioning, activities, and transfers).
  • Communicate with you before, during, and after your charter (including confirmations, updates, and customer support).
  • Arrange required formalities with marinas, ports, and local authorities, including passenger manifests and compliance with maritime, immigration, customs, and safety regulations.
  • Process payments, issue invoices, and handle refunds or chargebacks.
  • Comply with legal, tax, accounting, and regulatory obligations.
  • Improve our website, services, and customer experience (including analytics and testing).
  • Send marketing communications (such as newsletters and offers) where you have consented or where otherwise permitted by law.
  • Detect, prevent, and investigate fraud, unauthorized access, and misuse of our services.

Where required by applicable law (e.g., in the EU/UK), we rely on the following legal bases for processing:

  • Performance of a contract: to fulfill your charter booking and related services.
  • Legal obligation: to comply with maritime, tax, immigration, safety, and other laws.
  • Legitimate interests: for service improvement, security, and certain marketing activities, provided these do not override your rights.
  • Consent: for optional marketing and other specific uses where we ask for your explicit agreement.

Who we share your data with

We may share your personal data with the following categories of recipients, as necessary to provide our yacht charter and related services:

  • Charter operators and yacht owners to confirm and operate your booking.
  • Crew, skippers, and on‑shore service providers (e.g., catering, transfers, activities, maintenance).
  • Payment processors and financial institutions to process payments and refunds.
  • Insurance providers for charter, travel, or liability insurance.
  • Marinas, ports, and local authorities as required for check‑in, passenger manifests, and compliance with maritime, immigration, customs, and safety regulations.
  • Technology providers that host our website, manage bookings, handle email/SMS communications, or provide analytics, support, and security tools.
  • Professional advisors and authorities where required by law or to protect our rights, safety, or the safety of others.

We do not sell your personal data to third parties for their own marketing purposes.

How long we retain your data

We retain your personal data only for as long as necessary to:

  • Perform and administer your charter contract and related services.
  • Comply with legal, tax, accounting, and regulatory obligations (which may require us to keep certain records for several years).
  • Handle any disputes, claims, insurance matters, or security investigations.

Specifically:

  • Comments: We do not currently allow comments. If we enable comments in the future, we will retain a comment and its metadata only if you choose to leave a comment. In that case, the comment and its metadata would be retained indefinitely so we can recognize and approve any follow‑up comments automatically.
  • User accounts: We do not currently offer user accounts or login. If we enable accounts in the future, we will store personal information in your user profile only if you choose to register and log in. In that case, you would be able to see, edit, or delete your personal information at any time (except you would not be able to change your username). Website administrators could also see and edit that information.
  • For charter bookings and inquiries, booking and contract data may be kept for up to 6 years after your charter ends or after our last communication with you, in line with typical Greek and EU tax, commercial, and limitation‑period requirements.
  • Marketing data is kept until you unsubscribe or after a defined period of inactivity (e.g., 24 months), unless you choose to remain subscribed.
  • Technical and usage data (such as analytics logs) is retained for 12 months, unless needed for security investigations.

What rights you have over your data

Depending on your location, you may have the following rights regarding your personal data:

  • Access: request a copy of the personal data we hold about you.
  • Correction: request correction of inaccurate or incomplete data.
  • Deletion: request erasure of your personal data, subject to legal obligations to retain certain information.
  • Restriction/objection: request restriction of processing or object to certain types of processing.
  • Data portability: receive your data in a structured, commonly used, machine‑readable format.
  • Withdrawal of consent: withdraw consent at any time where processing is based on consent (without affecting the lawfulness of processing before withdrawal).
  • Complaint: lodge a complaint with a data protection authority if you believe your rights have been violated.

If, in the future, you have an account on this site or leave comments, you can request to receive an exported file of the personal data we hold about you, including any data you have provided to us (such as booking details, contact information, and preferences). You can also request that we erase any personal data we hold about you, except data we are obliged to keep for administrative, legal, or security purposes.

To exercise these rights, please contact us at themis.sailing@gmail.com. We may need to verify your identity before responding.

Where your data is sent

Your personal data may be transferred to and processed in countries other than your own, including where our charter operators, crew, service providers, or technology partners are located. These countries may have different data protection laws than your country of residence. Where required by law, we use appropriate safeguards (such as standard contractual clauses or other legally approved mechanisms) to protect your data during such transfers.

Security

We implement technical and organizational measures to protect your personal data against unauthorized access, alteration, disclosure, or destruction. These include secure servers, encryption where appropriate, access controls, and staff training. However, no method of transmission over the internet or electronic storage is 100% secure, and we cannot guarantee absolute security.

Children’s privacy

Our services are not directed to children under 16. We do not knowingly collect personal data from children under 16 without appropriate parental or guardian consent. If you believe we have collected personal data from a child under 16 without such consent, please contact us and we will take steps to delete that information.

Changes to this Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or business operations. The “Last updated” date at the top of this page will indicate when changes were made. We encourage you to review this Privacy Policy periodically.
