Privacy Policy
Last updated: 26 October 2026
This Privacy Policy explains how Sim2Sky Ltd ("we", "us", "our") collects, uses, and protects your personal data when you use High Performance Pilot ("the app") at highperformancepilot.com.
We are committed to protecting your privacy and complying with the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018.
Who We Are
Sim2Sky Ltd is a company registered in England and Wales. We operate High Performance Pilot, a professional development platform for pilots built around the ICAO/EASA Core Competency framework.
For data protection queries, contact us at: support@highperformancepilot.com
What Data We Collect
We collect the following personal data when you use the app:
- Account data — your email address and display name, provided when you create an account
- Role data — your selected pilot role (e.g. First Officer, Captain) within the app
- Usage data — your progress, completed sessions, and behaviour ratings within the app
- Profile and reflection data — the development profile you choose to complete (for example your current challenge, recent simulator feedback, strengths and aspirations) and the reflections you write after practice sessions
- Payment data — handled entirely by Stripe. We do not store your card details. We receive confirmation of subscription status from Stripe.
- Technical data — device type, browser, and usage patterns collected automatically by Firebase
- Email marketing data — if you sign up to receive emails via the Insights site, we collect your first name and email address with your explicit consent. You may unsubscribe at any time using the link in any email we send.
- Reminder settings — if you switch on reminder emails, whether they are on, the time you chose and your time zone, plus when we last sent you one
- Practice in progress — when you tap Start practising, the behaviour and level you're practising and the date you started, so you can carry on across devices and we can check in on how it's going
- Sign-up information — the page you arrived from when you created your account and your time zone, so we can understand which content brings pilots to us and send emails at a sensible time of day
How We Use Your Data
We use your personal data to:
- Provide and maintain your account and subscription
- Track and display your development progress within the app
- Generate your personalised Flight Plan, reflection feedback and Elite report, using our coaching algorithm partners (see Third Party Services)
- Process subscription payments via Stripe
- Communicate with you about your account or subscription
- Send you a short series of welcome emails after you create an account, and practice reminder emails if you switch them on (see Emails We Send)
- Improve the app and user experience
Legal Basis for Processing
We process your personal data on the following legal bases:
- Contract — processing necessary to provide the service you have subscribed to
- Consent — where you have explicitly opted in to receive marketing emails. You may withdraw consent at any time by unsubscribing.
- Consent — to send your profile and reflections to our coaching algorithm partners to generate your Flight Plan, reflection feedback and Elite report. We ask for your permission before the first time, and nothing is sent unless you agree. You may withdraw consent at any time by contacting us; the rest of the service is unaffected.
- Consent — to send you practice reminder emails. They are off unless you switch them on, and you can switch them off at any time in Settings or with the link in any reminder.
- Legitimate interests — improving and maintaining the app, preventing fraud, sending a short series of welcome emails to help you start using the service you signed up for, and checking in on a practice session you have started. You can stop these at any time with the link in each email.
- Legal obligation — where required by law
Emails We Send
Apart from emails about your account or subscription, we send four kinds of email. Each is sent from David at High Performance Pilot, and each has its own off switch.
- Welcome emails — when you create an account, we send a welcome email with a link to your first session. If you haven't started a session, we follow up once after two days and once more after six days. These stop as soon as you practise, and you can stop them at any time with the link in the email. We don't send any more welcome emails after that.
- Practice reminders — only if you switch them on in Settings. A reminder is sent at the time you choose, and only on days you haven't practised. If three reminders go unanswered, they pause automatically and we tell you in the third one. You can switch them off at any time in Settings or with one tap in any reminder.
- Practice check-ins — when you tap Start practising on a How-To, we check in three days later to ask how it's going, with a link to add your reflection or to say you're still practising. We check in at most every three days, and the session closes on its own after 14 days. You can stop these at any time with the link in the email.
- Newsletter — only if you sign up to it on our website. You can unsubscribe at any time using the link in any newsletter.
Welcome emails, reminders and check-ins are sent through Brevo's transactional email service. Your address is not added to our newsletter list unless you sign up to it separately. If you reply to any of our emails, your reply comes to support@highperformancepilot.com.
Third Party Services
We use the following third party services to operate the app:
- Firebase (Google) — authentication, database, and hosting. Data may be stored on Google servers within the EEA. See Firebase Privacy.
- Stripe — payment processing. Stripe is responsible for the security of your payment data. See Stripe Privacy Policy.
- Netlify — hosting for the website and the app, and the server functions that run parts of the service, such as sending emails and generating your Flight Plan. See Netlify Privacy Policy.
- Brevo (Sendinblue) — sends our emails: the newsletter if you sign up to it, welcome emails after you create an account, and practice reminders if you switch them on. Brevo receives your email address and first name, and keeps a record of emails sent to you so we can check they were delivered. Brevo is based in the EU. See Brevo Privacy Policy.
- Google reCAPTCHA — spam protection on our signup forms. reCAPTCHA collects hardware and software information and sends it to Google for analysis. See Google Privacy Policy.
- Anthropic — coaching algorithm partner. When you use the Flight Plan, reflection feedback or Elite report, and only with your permission, your profile and reflections are sent securely to Anthropic to write your coaching. Under Anthropic's commercial terms, this data is not used to train its models, and it is not used for advertising. See Anthropic Privacy Policy.
- Voyage AI (MongoDB) — coaching algorithm partner. When you generate a Flight Plan, and only with your permission, a short summary of your profile (such as your current challenge and simulator feedback) is sent securely to Voyage AI to find the most relevant material in our coaching library. This data is not used to train its models, and it is not used for advertising. See MongoDB Privacy Policy.
- Google Analytics (GA4) — usage analytics across the website and the app, used only if you accept analytics cookies. GA4 collects usage data such as pages visited, time on site and the features used. We do not send your name, email address or the content of your reflections to Google Analytics. See Google Privacy Policy.
