BosunMarineBosunMarine Privacy Policy
BosunMarine ("BosunMarine," "we," "us," or "our") is a mobile and web app that helps boat owners understand their boat. Its AI assistant, Bosun, answers questions about your boat, and the app organizes your manuals and documents and builds a searchable record of the boat's systems. This policy explains what information BosunMarine collects, why, and how it is used, stored, and shared.
Who operates BosunMarine
BosunMarine is operated by Sunny Corner Coffee, trading as BosunMarine (ABN 33 728 186 744), of Bellingen NSW, Australia. If you have questions about this policy or your data, contact us at support@bosunmarine.app.
Information we collect
Account information
BosunMarine uses Auth0 to handle sign-in. When you create an account or log in, we receive your email address, display name, and profile picture (if your sign-in method provides one), along with an authentication token that identifies your session. We do not receive or store your password — Auth0 handles that directly.
Content you provide
Using BosunMarine involves giving it information about your boat so it can help you. This includes:
- Details about your boat that you enter or that BosunMarine asks about during onboarding (make, model, systems on board, and similar);
- Manuals, documents, and photos you upload — for example, equipment manuals, nameplates, or photos of a part or issue you're asking about;
- Files you choose in Dropbox. When you add documents "From Dropbox", Dropbox gives us a short-lived link to only the files you pick, and our server downloads them. We never receive your Dropbox password or access to the rest of your Dropbox;
- Files you choose in Google Drive. When you add documents "From Google Drive", Google asks you to let BosunMarine see only the files you pick (Google's drive.file permission). Google gives our server a token that lasts about an hour, our server downloads those files with it (Google Docs, Sheets and Slides as PDFs), and the token is then discarded. We never receive your Google password or access to anything else in your Google Drive. BosunMarine's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements;
- Your chat messages, questions, and notes, and Bosun's responses to them.
Photos come from your device's camera or photo library, which the app only accesses when you choose to attach a photo. BosunMarine does not access your photo library or camera in the background.
Your email, if you leave it on our website
If you leave your email address in the "Not ready yet?" box on bosunmarine.app without making an account, we keep that address, the day you left it, and which page it came from. We use it only to write to you now and then about BosunMarine. Every email has a link that takes you off the list, and you can ask us to delete the address at support@bosunmarine.app.
Location (only if you turn it on)
If you turn on "Use my location" in Settings, the app sends your rough position (rounded to about 10 km) with each chat message, so Bosun can answer questions that depend on where you are, such as weather, tides, local rules, or where to find parts. It goes with that message to the AI model and, if Bosun searches the web for you, a nearby place name may go to our search provider (see "AI processing" below). We don't save your position to your account. A web search's words show in the answer's working steps, which we clear after a week. Location stays off unless you turn it on, your device or browser asks your permission first, and you can turn it off at any time. The app also sends your device's time zone with each message so Bosun knows your local date and time; the time zone is kept with the chat.
Payment information (subscriptions)
BosunMarine offers a free tier and a paid subscription. Payment is handled by third parties, not by BosunMarine directly:
- On iOS, subscriptions are purchased through Apple's In-App Purchase system. Apple processes your payment; BosunMarine never sees your card details. We receive subscription status (such as which plan you have and whether it's active) through RevenueCat, which relays that status from Apple to our servers.
- On the web, subscriptions are purchased and managed through Stripe. Stripe processes and stores your payment details under its own privacy policy; we receive your subscription status and billing events, not your full card number.
Technical and usage information
Like most apps and websites, our servers keep standard request logs (such as IP address, timestamps, and the page or endpoint requested) for operating and securing the service. BosunMarine does not use third-party analytics, advertising, or crash-reporting SDKs — we don't share your usage patterns with an ad or analytics network, because we don't have one integrated.
How we use your information
- To provide the core BosunMarine experience: answering your questions, organizing your boat's manuals and documents, and keeping your chat history and notes.
- To process the manuals, photos, and questions you provide using AI models, so Bosun can generate answers and summaries (see "AI processing" below).
- To authenticate you and keep your account secure.
- To process payments and manage your subscription.
- To maintain, secure, and improve the service, and to diagnose problems.
AI processing
When you ask Bosun a question or upload a manual, the relevant content (your message, and/or the text and images extracted from your document) is sent to an AI model to generate a response. BosunMarine currently uses:
- Anthropic's Claude models, served through Microsoft's Azure AI Foundry,
- OpenAI models, served either directly or through Microsoft's Azure AI Foundry, and
- Google's Gemini API.
When you talk to Bosun in a voice call, your voice is sent to OpenAI or Google so the model can hear you and speak Bosun's answer. Dictating into the text box on an iPhone uses Apple's own speech recognition. Calls are not recorded by BosunMarine: the audio of a call is not stored. Voice memos you record yourself are stored with your documents.
When Bosun searches the web, for example to look up your boat's make and model or to answer a question your manuals don't cover, the search words are sent to the AI model's own web search (Anthropic's, through Azure AI Foundry).
These providers process the content you send in order to generate a response; they act as our data processors for this purpose under their own respective terms, not as independent owners of your data. We may change which AI providers we use as the product evolves.
Where your data is stored
BosunMarine's database and file storage run on Microsoft Azure. Uploaded manuals and photos are stored in Azure Blob Storage; your account records, boat data, chat messages, and notes are stored in an Azure-hosted PostgreSQL database. Data is stored in Microsoft Azure's Australia East and Australia Southeast regions.
Who we share information with
We share information with the service providers who help us run BosunMarine, and for no other commercial purpose. We do not sell your personal information, and we do not share it with advertisers.

Data retention
We keep your account and boat data for as long as your account is active, so BosunMarine can keep working the way you'd expect — remembering your boat and past conversations. If you delete your account, we delete or anonymize your personal data within 30 days, and from our backups within 35 days, except where we're required to keep records (for example, billing records) for longer under law.
Your choices and rights
You can review and correct the boat information stored in the app at any time. You can delete your account and its data yourself in the app's account settings. To request a copy of your data, or to ask a question about how your data is handled, contact support@bosunmarine.app. We answer within 30 days.
Australia. Under the Privacy Act 1988 and the Australian Privacy Principles you can ask to see and correct the personal information we hold about you. If you're not satisfied with how we handle a complaint, you can contact the Office of the Australian Information Commissioner (oaic.gov.au).
European Union and United Kingdom. Under the GDPR and UK GDPR you have the right to access, correct, delete or receive a copy of your personal data, to restrict or object to how we use it, and to withdraw consent where we rely on it. We use your data to provide the service you signed up for (performing our contract with you) and, for security and fraud prevention, our legitimate interests. Your data is processed outside your country by the providers listed above; where the law requires it, those transfers rely on the providers' standard contractual clauses. You can complain to your local data protection authority.
California. Under the CCPA you can ask what personal information we collect and how we use it, ask us to delete or correct it, and use these rights without being treated differently. We do not sell or share your personal information for advertising.
Children's privacy
BosunMarine is not directed at children, and we don't knowingly collect personal information from children under 18. If you believe a child has provided us personal information, contact us and we will delete it.
Security
We use encryption in transit and access controls to protect your information. No method of storage or transmission is completely secure, and we can't guarantee absolute security.
International data transfers
BosunMarine is operated from Australia and stores data in Microsoft Azure's Australia East region. If you use BosunMarine from another country, your information will be transferred to and processed there.
Changes to this policy
We may update this policy as BosunMarine changes. If we make material changes, we'll notify you in the app or by email before they take effect. The "Last updated" date above reflects the most recent revision.
