Privacy policy
Last updated: 22 October 2026
In short: we collect only what we need to coach you. Health information is used only with your explicit consent, kept secure and never sold. You can ask to see or delete your data at any time by emailing hello@myostays.com.
Who we are
MYO·STAYS is run by David Barbeiro, a sole trader based in London, United Kingdom. David is the data controller for the personal information described here.
Contact: hello@myostays.com
What we collect
- Free guide and waitlist: your first name, email address, which stage you're at, and your confirmation that you're 18+ and agree to receive emails.
- Founding place purchase: your name, email address and phone number. Payments are handled by Stripe; we never see or store your full card details.
- Coaching: your answers to our health and fitness questionnaire, your goals, training preferences, injuries, the messages you send us on WhatsApp, meal photos you choose to send, and your weekly check-ins (weight, waist, energy and strength).
Health information is "special category" data under UK GDPR. We only collect it with your explicit consent, which you give when you complete the health questionnaire, and you can withdraw it at any time.
How we use it and why
| Purpose | Lawful basis |
|---|---|
| Sending you the free guide and MYO·STAYS updates | Your consent |
| Taking payment and providing the coaching you signed up for | Contract |
| Using your health and check-in information to build and adjust your plan | Your explicit consent |
| Keeping the service safe, fixing problems and improving our coaching | Legitimate interests |
| Keeping financial records | Legal obligation |
How the AI coach uses your information
Your coach's replies are written by an AI system. To do that, your recent messages, plan and check-ins are sent to our AI provider to generate each reply. The AI provider processes this information on our behalf and does not use it to train its models. A real person reviews conversations every day.
The AI only chooses from an approved library of exercises and never makes medical decisions. No decision with legal or similarly significant effects on you is made automatically.
Who we share it with
We never sell your information. We share it only with service providers who help us run MYO·STAYS, under contracts that protect it:
- Stripe: payments
- Google: storing sign-ups and sending emails
- Cloudflare: hosting this website and handling email for myostays.com
- Meta (WhatsApp) and our WhatsApp messaging provider: delivering coaching messages
- Our AI provider: writing coach replies
- Our server and database host in the EU: storing member records
Some of these providers process data outside the UK, for example in the EU or the United States. When they do, the transfer is covered by UK adequacy regulations or the UK's approved data transfer agreements.
How long we keep it
- Free guide and waitlist: until you unsubscribe or ask us to delete it.
- Coaching and health information: while you're a member, then deleted within 30 days of you leaving, unless you ask us to delete it sooner.
- Payment and financial records: 6 years, as required by HMRC.
Your rights
You can ask us to:
- give you a copy of your information
- correct it
- delete it
- restrict or object to how we use it
- send it to you or another service in a portable format
- stop using it where we rely on your consent (this won't affect what we did before)
Email hello@myostays.com and we'll reply within one month.
If you're unhappy with how we handle your information, you can complain to the Information Commissioner's Office at ico.org.uk or on 0303 123 1113. We'd appreciate the chance to put things right first.
Cookies
This website doesn't use advertising or tracking cookies. It loads fonts from Google Fonts, which means your browser shares your IP address with Google. When you pay, you go to Stripe's checkout page, which sets its own cookies to process the payment and prevent fraud.
Children
MYO·STAYS is only for adults aged 18 and over. We don't knowingly collect information about anyone under 18.
Changes
If we change this policy, we'll update the date at the top. If the change is significant, we'll tell members by email or WhatsApp.
