Privacy Policy

Last updated: October 31, 2026
Version
1.1
Effective date
October 31, 2026

Notice at collection (California and other US states). We collect the categories of personal information listed in Section 2 and Section 17.6 for the purposes in Section 3. We keep each category for the periods in Section 13. Section 10 explains the information we collect from public sources for the Collective.

We do not sell personal information for money. Our website uses Google and Meta advertising measurement tags, and some state laws treat that as "selling" or "sharing" personal information for cross-context behavioral (targeted) advertising. You can opt out at the "Your Privacy Choices" link in the footer of our Websites or by sending a Global Privacy Control signal (Section 6).

We do not use sensitive personal information to infer characteristics about you (Section 7).

1. Who We Are and What This Policy Covers

1.1 Who we are. CelesteOS LLC ("Company", "we", "us", "our") is a Florida limited liability company located at 7901 4th St N, #36609, St Petersburg, FL 33702, USA. We provide CelesteOS, a hosted software platform that yacht operators and management companies use to manage maintenance, safety and compliance records for their vessels (the "Service").

1.2 Defined terms in this Policy.

1.3 What this Policy covers. This Policy explains how we handle personal information when:

(a) you visit our Websites, the Collective Site or the Verifier;

(b) you contact us, book a demonstration or otherwise deal with us as a prospective customer, partner or supplier;

(c) you use the Service or sign in to the Collective Site as an Authorized User. For this item, it covers only the account, security and relationship information we use for our own purposes (see Section 1.4); and

(d) content you or others published on a public website (such as a forum post or a question-and-answer post) is collected as Public-Source Content (Section 10).

1.4 What this Policy does not cover: Customer Data. The crew records, certificates, operational records, documents and other Customer Data in the Service belong to the Customer that subscribed to the Service. For Customer Data, the Customer is the controller (or "business"), and we act only as its processor or service provider under a written data processing agreement. If you are a crew member or other person whose information appears in a Customer's records, the Customer's own privacy notice applies. Please send requests about those records to the Customer, usually your employer or the vessel's management company. If you contact us instead, we will pass your request to the relevant Customer (Section 17.3).

1.5 Related notices. Please also read our Cookie Notice (https://celeste7.ai/cookies) and our public Sub-processor List (https://celeste7.ai/subprocessors).

2. Personal Information We Collect

2.1 Information you give us.

2.2 Information we receive from your organization. A Customer may create your Authorized User account and give us your name, work email, role and vessel assignment.

2.3 Information we receive from Microsoft. If you choose "Sign in with Microsoft", Microsoft confirms your identity to us and sends us your name, work email address, a directory identifier and your organization's tenant identifier. We never receive your Microsoft password. We also use Microsoft's services to verify sign-ins and to send the service emails described in Section 3(a) from an email account we control. We do not read or access your own email.

2.4 Information collected automatically.

2.5 Information from public and professional sources. We may collect business contact details of prospective customers from publicly available professional sources, such as company websites and industry directories. For the Collective, we also collect content from public websites, which may include user names and other personal information (Section 10).

3. How We Use Personal Information

We use personal information to:

(a) provide and administer accounts: create and manage Authorized User accounts, authenticate users and send service messages (such as password-reset emails, sign-in verification codes and account notices);

(b) secure the Service: detect and prevent unauthorized access, fraud and abuse, including through sign-in lockouts and session revocation;

(c) support you: respond to questions and support requests;

(d) run our customer relationships: manage subscriptions, invoicing and renewals;

(e) communicate with prospects: respond to enquiries, arrange demonstrations and send business-to-business information about the Service. You can opt out at any time (Section 17.1);

(f) understand and improve our Websites: measure traffic and how visitors use our pages, using analytics tools where you allow them (Section 5);

(g) measure our advertising: learn whether our online ads lead to visits or enquiries, where you allow this (Section 5);

(h) comply with law and protect rights: meet legal, tax and accounting obligations, respond to lawful requests, and establish or defend legal claims;

(i) handle business transfers: as part of a merger, financing, acquisition or similar transaction (Section 4.1(f));

(j) create de-identified or aggregated information that no longer identifies anyone, for purposes such as improving the Service. We do not attempt to re-identify de-identified information, except to test whether our de-identification methods meet legal requirements; and

(k) operate the Collective's public-source knowledge base: collect, organize and display Public-Source Content so that vessel engineers can find reported equipment faults and fixes (Section 10).

4. How We Disclose Personal Information

4.1 Recipients. We disclose personal information to the following categories of recipients:

(a) Service providers that help us run our business and the Service. These include cloud hosting and storage, edge network and security services, a session-security cache, identity and transactional email services, error monitoring, push-notification delivery and customer support tools. They may use personal information only to provide services to us.

(b) Third-party AI model providers, which process content when you use AI features of the Service (Section 8).

(c) Analytics and advertising partners: Google, Meta, and our session-analytics provider, on our Websites only, subject to your choices (Sections 5 and 6).

(d) Our bank, which handles the bank details in payments made to us under its own privacy terms.

(e) Your organization. If you are an Authorized User, the Customer that gave you access can see your account details and activity in the Service.

(f) Professional advisers, acquirers and investors, under confidentiality obligations, including in connection with a merger, acquisition, financing, sale of assets or similar transaction.

(g) Authorities and others, where we believe in good faith that the law requires disclosure, or that disclosure is needed to protect rights, safety or property.

(h) Others at your direction, for example where you ask us to share information.

(i) Signed-in users of the Collective Site, who can see Public-Source Content, including user names or display names as they appeared in the original source (Section 10).

4.2 Customer Data. We disclose Customer Data only on the Customer's instructions and to the sub-processors listed in our Sub-processor List.

5. Cookies, Analytics and Advertising on Our Websites

5.1 What we use. On our Websites we use the following, as described in detail in our Cookie Notice:

5.2 Consent. Analytics, advertising and session-analytics tools are off by default until you accept them in our consent banner. No Google, Meta, Contentsquare or other third-party measurement script is loaded before you make a choice, and none is loaded for a category you reject. If you accept analytics and advertising, our own systems may also report a demo-booking click or enquiry directly to Meta (Conversions API) and Google, with the same event identifier as the browser report so it is counted once; for an enquiry this can include your email address in one-way hashed form (see the Cookie Notice, Section 3.4). You can change your choice at any time through the "Your Privacy Choices" link in the footer of every page.

5.3 Google's and Meta's use. Google and Meta may use information collected through these tools under their own terms. You can learn how Google uses information from sites that use its services at policies.google.com/technologies/partner-sites, and how Meta does at facebook.com/privacy/policy. You can also install Google's Analytics opt-out browser add-on. For visitors in the UK and EEA, we and Meta Platforms Ireland Limited are joint controllers for collecting information through the Meta Pixel on our Websites and transmitting it to Meta; Meta is responsible for its later processing.

5.4 The Service, the Collective Site and the Verifier. The Service does not use cookies. It uses browser storage and an offline cache that are strictly necessary for the Service to work (Section 12). The Collective Site uses no cookies or analytics; it keeps a session token in your browser's local storage while you are signed in (Section 9.5), and serves all of its files from its own domain. The Verifier uses no cookies, browser storage or analytics, and its fonts are served from our own site (Section 11).

6. "Sale" and "Sharing" of Personal Information; Targeted Advertising

6.1 What we do. We do not sell personal information for money. However, when you allow advertising measurement on our Websites, Google and Meta receive online identifiers and information about your activity on our Websites. They may use this information for its own advertising purposes. Under California law this may be "sharing" for cross-context behavioral advertising. Under other state laws it may be "targeted advertising" or a "sale". We treat it as such.

6.2 What is involved. The categories involved are identifiers (such as cookie IDs and IP address), internet activity on our Websites, and approximate location. The recipients are our advertising partners, Google and Meta. We do not sell or share Customer Data, account data from the Service, or sensitive personal information.

6.3 How to opt out. You can opt out of the sale or sharing of your personal information, and of targeted advertising, in any of these ways:

Because opt-outs made through cookies or GPC are stored in your browser, they apply only to that browser and device.

6.4 Children. We do not knowingly sell or share the personal information of anyone under 16.

7. Sensitive Personal Information

7.1 What we collect. The only sensitive personal information we collect as a controller is account log-in credentials (your user name together with your password, which we store only in hashed form). We use them only to authenticate you and secure your account. We do not use or disclose sensitive personal information to infer characteristics about you, or for any purpose that would give rise to a right to limit its use under California law.

7.2 Sensitive information in Customer Data. A Customer may choose to store crew documents in the Service that contain sensitive information, such as medical fitness certificates or passport details. We process those only as the Customer's processor (Section 1.4).

8. Artificial Intelligence Features

8.1 What the AI features do. The Service includes features powered by third-party AI model providers, which provide:

8.2 What is sent. When these features run, the text of the relevant records or documents, or page images, is sent to the AI model provider. We send only what each feature reasonably needs. We do not remove names or vessel names before sending. The only exception is that we mask email addresses and telephone numbers in text used to build search indexes.

8.3 No training. Our contracts with, or the published terms of, our AI model providers do not permit them to use content sent through the Service to train their models.

8.4 Retention by providers. Some providers keep inputs for a limited period for abuse monitoring, which for at least one provider is up to 30 days, before deleting them.

8.5 Outputs can be wrong. AI outputs can be inaccurate or incomplete. The Service does not use AI to make decisions about individuals that have legal or similarly significant effects. Decisions remain with the vessel's Master, crew and the Customer.

9. The Collective

9.1 What it is. The Collective is an engineering-knowledge service about equipment failures and fixes. The Collective Site displays Public-Source Content (Section 10). Once fleet-contributed insights are published, participating Customers will also see de-identified insights built from the contributions of participating fleets there. Participating Customers contribute engineering information from their own records so that the whole fleet can learn which problems recur and what solved them. Sections 9.2 to 9.4 describe how that works. A Customer's data is never used for the Collective unless that Customer has opted in.

9.2 Opt-in by Customers only. A Customer's data is used for the Collective only if that Customer opts in through its contract with us. Individual crew members do not opt in or out themselves. Questions about whether your organization participates should go to your organization.

9.3 What is shared. If a Customer opts in, before anything is shared:

What participants will see are de-identified engineering patterns, not crew information and not any one vessel's records.

9.4 Pseudonymized is not anonymous. The pseudonymized contributions are not anonymous, and we protect them as personal information where they relate to an identifiable person. Insights published to participants are de-identified.

9.5 Signing in to the Collective Site. You sign in to the Collective Site with your CelesteOS account. We use the same account system as the Service and process your sign-in information as described in Section 2.4. While you are signed in, your browser keeps a session token in local storage so that you stay signed in; it is removed when you sign out. We do not use analytics or advertising tools on the Collective Site, and we do not record your searches for any purpose other than delivering results and keeping the site secure.

10. Information We Collect from Public Sources (Collective)

10.1 What we collect and from where. For the Collective, we collect posts, reports and other content that has been published on publicly accessible websites. Our sources include public accident-investigation and incident reports, industry safety notices, maritime and yachting news sites, public boating and engineering forums and discussion boards, public question-and-answer sites, public video and code-hosting platforms, and published equipment manuals. From these sources we may collect:

10.2 Why we collect it. We use this information to build a searchable knowledge base of reported equipment faults, the remedies people tried, and the reported outcomes, so that vessel engineers can find relevant experience quickly (Section 3(k)). We do not use it to contact, profile or market to the people who wrote it, and we do not combine it with other information to identify them.

10.3 How we process it. Our automated tools collect the content and then use AI models to extract technical fields (such as equipment, manufacturer, model and root cause) and to label reported outcomes. At present, these AI models run on our own equipment, and we do not send Public-Source Content to third-party AI model providers. If that changes, we will update this Policy first.

10.4 Who can see it. Public-Source Content is shown to signed-in users of the Collective Site, with a link to the original source where we have one. It may include the user name or display name under which the content was originally published.

10.5 How we limit personal information. We remove email addresses and telephone numbers from the text of collected content. We use automated tools to detect and remove other people's names from the text where they can, but these tools do not catch every name. User names and titles are currently displayed as they appeared in the original source. We are updating our collection process so that author names and handles are no longer stored, and are working to remove them from existing records. We will remove or reduce any item on request (Section 10.8).

10.6 Legal basis and this notice (EEA, UK and Switzerland). We rely on our legitimate interests, and the interests of the vessel engineers who use the Collective, in making publicly reported technical experience about equipment faults easier to find, which supports safe and reliable vessel maintenance. We have balanced these interests against the interests of the people concerned, taking into account that the content was published publicly in a technical context, the measures in Section 10.5, and your right to object. You can ask us for details of this assessment. This Section 10 is our notice to the people whose information we collect from public sources, as required by Article 14 of the GDPR and UK GDPR. We generally do not hold contact details for the authors of public posts, so contacting each of them individually would be impossible or would involve disproportionate effort, and would require us to collect more personal information about them. We therefore make this information publicly available here instead.

10.7 Retention and location. We keep Public-Source Content for as long as the item remains useful to the knowledge base, and we remove it promptly on a valid objection or takedown request (Section 10.8). It is stored with our primary hosting provider in Germany. Collection and processing also take place on our own equipment in the United States.

10.8 Your choices and rights. If you believe your information appears in Public-Source Content, you can ask us to remove it, correct it, give you a copy, or stop processing it, by emailing contact@celeste7.ai with the user name or a link to the item or the original post. In the EEA, UK and Switzerland, you have the right to object to our processing based on legitimate interests (Section 18.3). We will stop displaying an item promptly while we review a request, and we will remove your information unless we have compelling legitimate grounds to keep it or the law requires otherwise. If you have deleted or edited the original post, please tell us, and we will update or remove our copy. These rights apply in addition to the rights in Sections 17 and 18.

10.9 US state privacy laws. Some US state privacy laws, including California's, exclude "publicly available information" from the personal information they regulate. Under California law, that exclusion covers only information that is lawfully made available from government records, or that a business has a reasonable basis to believe is lawfully made available to the general public by the person concerned or by widely distributed media. Not all Public-Source Content may meet that test. Whether or not an exclusion applies, we will honor requests about Public-Source Content as described in Section 10.8. We do not sell or share Public-Source Content.

10.10 Copyright and other requests. Requests from authors or rights holders about the content itself, rather than personal information, can be made under our Terms of Use.

11. The Verifier

11.1 Your file is never uploaded. The Verifier lets anyone check whether the content of a sealed record export matches the integrity digests recorded in it. It runs entirely in your web browser. The file you check is never uploaded to us, and the Verifier makes no network requests during the check and uses no cookies, browser storage or analytics.

11.2 Page hosting. When your browser loads the Verifier page, our hosting provider receives standard technical information, such as your IP address and browser type, as for any web page. That information is used only to deliver and secure the page. The Verifier's fonts are served from our own site, and the Verifier loads no files from third parties.

11.3 What the check covers. The Verifier checks the file's internal content integrity. It does not currently validate the digital signature.

12. The App on Your Device: Browser Storage and Offline Access

12.1 What is stored on your device. To keep you signed in and to let you work on board with poor connectivity, the Service stores the following in your browser:

(a) your session token, user identifier, email address, role and vessel name, in your browser's local storage; and

(b) copies of records you have viewed, for up to 7 days, in an offline cache. The cache is kept separately for each user and each vessel, is deleted when you sign out, and never includes crew certificates.

12.2 Not encrypted by the app. This stored information is not encrypted by the Service on your device. Anyone with access to your unlocked device or browser profile could read it. Please use device encryption and a screen lock, and sign out on shared devices. Your organization may have its own device rules.

12.3 Push notifications. If you enable push notifications, your browser registers with its push service (operated by your browser or device maker), and notification titles and text pass through that service.

13. Retention

We keep personal information only as long as needed for the purposes in Section 3, then delete or de-identify it.

InformationRetention
Website analytics data (Google Analytics)14 months
Advertising measurement and session-analytics dataAs set by those tools; see the Cookie Notice
Consent choices12 months, after which we ask again
Prospect enquiries and contact details24 months after our last contact with you, unless you become a customer or ask us to delete them sooner

Public-Source Content (Collective)For as long as the item remains useful to the knowledge base; removed promptly on a valid objection or takedown request (Section 10)
Hosting logs for the Collective Site and the VerifierAs set by our hosting provider, currently 30 days

14. Security

We use administrative, technical and organizational measures designed to protect personal information, including:

No method of transmission or storage is completely secure, and we cannot guarantee the security of personal information.

Security breaches. If a breach of security affects personal information that we control, we will notify affected individuals and regulators as the law requires. For example, for residents of Florida, we will notify affected individuals no later than 30 days after we determine that a breach occurred or have reason to believe one occurred (unless law enforcement asks us to delay or the law allows a short extension), and we will notify the Florida Department of Legal Affairs where 500 or more Florida residents are affected. If a breach affects Customer Data, we notify the affected Customer without undue delay, with a target of 48 hours after we confirm the breach, so that the Customer can meet its own notification duties.

Please tell us promptly at contact@celeste7.ai (subject line "Security") if you believe your account has been compromised.

15. International Transfers

15.1 Where information is processed. We are based in the United States. Our primary hosting for the Service is in Germany. Personal information is also processed in the United States and in other countries where our service providers operate, including by our edge network, session-security cache, AI model providers and Google. Public-Source Content is stored in Germany and is also collected and processed on our own equipment in the United States (Section 10.7).

15.2 Safeguards for EEA, UK and Swiss data. Where we transfer personal information from the European Economic Area, the United Kingdom or Switzerland to a country without an adequacy decision, we use appropriate safeguards. These include the European Commission's Standard Contractual Clauses, the UK International Data Transfer Addendum, and recipients' certifications under the EU-US Data Privacy Framework (including its UK Extension and the Swiss-US framework). You can ask for a copy of the relevant safeguards at contact@celeste7.ai.

16. Children

The Websites and the Service are intended for businesses and are not directed to children under 16. We do not knowingly collect personal information from children under 16 as a controller. If you believe we have done so, contact contact@celeste7.ai and we will delete it.

17. Your Privacy Rights

17.1 Everyone. Wherever you live, you can:

17.2 US state privacy rights. Depending on your state of residence, you may have some or all of the following rights. These may include California, Colorado, Connecticut, Virginia, Utah, Texas, Oregon and other states with comprehensive privacy laws.

Note that several states' laws do not apply to information about people acting in a business or employment capacity. California's law does apply to that information.

17.3 How to submit a request. Email contact@celeste7.ai with the subject "Privacy request". We conduct business online, so we accept requests by email.

17.4 Authorized agents. You may use an authorized agent to submit a request. We may require written, signed permission from you, may verify the agent's identity, and, unless the agent holds a valid power of attorney, may ask you to confirm your identity directly with us.

17.5 Appeals. If we decline your request, you may appeal by emailing contact@celeste7.ai with the subject "Privacy Appeal" within a reasonable time after our decision. We will respond in writing within the time your state's law requires (generally 45 or 60 days), explaining our reasons. If we deny your appeal, you may contact your state Attorney General.

17.6 California disclosures for the past 12 months.

We do not collect biometric information, precise geolocation, or protected classification characteristics as a controller, except where such information happens to appear in Public-Source Content (Section 10.1). Some Public-Source Content may be "publicly available information" outside the scope of California law; we list it here anyway (Section 10.9). We do not draw inferences to create profiles about you. Retention periods are in Section 13.

17.7 Shine the Light (California). We do not disclose personal information to third parties for their own direct marketing purposes.

17.8 Nevada. We do not sell covered information as defined by Nevada law. Nevada residents may still send an opt-out request to contact@celeste7.ai.

18. Additional Information for the EEA, UK and Switzerland

18.1 Controller. CelesteOS LLC is the controller of the personal information described in this Policy. For Customer Data, the Customer is the controller and we are its processor (Section 1.4).

Where we rely on legitimate interests, you can ask us for details of our balancing assessment.

18.3 Your rights. You have the right to:

We will respond within one month, extendable by two further months for complex requests, in which case we will tell you why. We do not make decisions about you based solely on automated processing that produce legal or similarly significant effects.

18.4 Erasure of records in the Service. Where your information is part of Customer Data, the Customer decides on erasure. Service records are kept in an append-only, tamper-evident form so that they remain reliable evidence for maritime safety and compliance purposes. Where erasure is required, it may therefore be carried out by removing or anonymizing your identifying details instead of deleting the underlying operational entry. Copies of sealed records that the Customer has already downloaded remain under the Customer's control.

18.5 Complaints. You may complain to the data protection authority where you live or work, or where an alleged infringement occurred:

We would appreciate the chance to address your concerns first.

19. Changes to This Policy

We may update this Policy from time to time. We will post the updated version with a new effective date. If changes are material, we will give additional notice, such as a notice on our Websites or an email to account holders.

20. Contact Us

Version 1.1 — effective October 31, 2026. Version 1.1 adds the Meta Pixel and server-side advertising conversions (Sections 5 and 6).
