Version 1.0 · Effective 19 August 2026
Sub-processors
Last updated: 19 August 2026
To run Yacht Masters Hub we rely on the third parties below. Each processes personal data only on our instructions and under data protection terms. We give notice of new sub-processors as set out in our Data Processing Addendum.
Currently in use
| Sub-processor | Purpose | Personal data processed | Processing location |
|---|---|---|---|
| Anthropic, PBC (Claude) | Generates the concierge's replies | The content of your messages, and the vessel and contact details held in the conversation | the United States (AWS us-east-1 and Vercel iad1) |
| Vercel, Inc. | Application hosting and content delivery | Everything sent to the Service, including IP address and request metadata | the United States (AWS us-east-1 and Vercel iad1) |
| Amazon Web Services (DynamoDB) | Vessel catalog storage | Vessel records. No contact details are stored here | the United States (AWS us-east-1 and Vercel iad1) |
| PostHog, Inc. | Product analytics | Session identifier, page and feature events. Email address on waitlist and account-creation events | the United States (AWS us-east-1 and Vercel iad1) |
| Microsoft Corporation (Clarity) | Session recording and heatmaps, so we can see where the product is awkward to use | A recording of how you used the page, plus your email address and plan once you are signed in. Passwords, payment fields, and email inputs are masked | the United States (AWS us-east-1 and Vercel iad1) |
Used once the relevant feature is enabled
These are contracted but not yet processing data. This table is updated when each goes live.
| Sub-processor | Purpose | Personal data processed | Processing location |
|---|---|---|---|
| Stripe, Inc. | Subscription billing and checkout | Name, email, billing address, and payment details, which are collected on their pages and never by us | the United States (AWS us-east-1 and Vercel iad1) |
| Resend | Transactional and notification email | Name and email address | the United States (AWS us-east-1 and Vercel iad1) |
Analytics
We use PostHog for product analytics: which pages are viewed, which features are used, and where a signup flow is abandoned. Events are sent from our servers, and are identified by a random session identifier. On a small number of events, such as joining a waitlist or creating an account, the identifier is your email address.
We also use Microsoft Clarity to record how pages are used, which shows us where people get stuck. Passwords, payment fields, and email inputs are masked in every recording.
Both are off until you allow them. Nothing is recorded or measured before you answer the banner, and you can decline without losing any part of the Service.
We run no advertising or cross-site tracking, and we do not sell or share personal data for behavioural advertising.
Vessel catalog
Vessel lookups are answered by VesselIQ, which we operate ourselves. It is not a third party and is not a sub-processor.
International transfers
The sub-processors above process data in the United States. Where we transfer personal data out of the EEA or the UK, we rely on the transfer mechanism described in our Privacy Policy.
