Privacy policy
This explains what information FlowState Fuelling collects, why, who can see it and what your rights are. We've kept it in plain English.
Who we are
Jonathan Heaney, trading as FlowState Fuelling is the data controller for the information you give us. We're registered with the UK Information Commissioner's Office (registration number ZC258994). Contact us about your data at jheaneynutrition@gmail.com.
What we collect
- Contact details: your name, email address and, if you give it, your phone number.
- Body and training information: age, sex, height, weight, sports, training history, your training week, goals and events.
- Health information: any medical conditions, medication and supplements you tell us about, digestion and gut issues, and whether your periods are regular. This is "special category" data under UK law and we treat it with extra care.
- Food and lifestyle: your diet, allergies and intolerances, and anything you share about work, sleep, stress or family life.
- As coaching continues: weekly check-ins, progress photos and messages with your coach.
- Carb Load Calculator: your first name, email, weight, race (name, date, start and expected finish time), how many meals and snacks you eat and your diet.
- How you found us: where you heard about us and any referral code.
Why we use it, and our legal basis
- To build and adjust your fuelling plan and deliver the coaching you've signed up for. Our legal basis is our contract with you.
- If you use the Carb Load Calculator, we use your details to make your plan and email it to you, with a reminder on your first load day and the evening before your race. That's the service you asked for (our contract with you), and you can unsubscribe from those emails in one click.
- If you tick the box to get fuelling tips, guides and offers by email, we use your email for that with your consent. Every email has an unsubscribe link, and you can ask us to stop at any time.
- We only use your health information with your explicit consent, which you give in the questionnaire. You can withdraw it at any time; without it we may not be able to coach you safely.
- Where you heard about us helps us understand what's working and, if you used a referral code (typed in or from a referral link), credit the person who referred you and give you any price or bonus that comes with their code. This is in our legitimate interests.
We never sell your information or use it for anyone else's marketing.
Who can see it
Only your coach. Your information is never shared with other clients. We use a small number of trusted services to run the app, which process it on our behalf and only as we instruct:
- Supabase, which stores the app's data in its London (UK) region.
- Vercel, which hosts the website and app.
- Stripe, if you pay by card: your name, email, card and payment details. We never see your full card number.
- Cal.com, if you book a call: your name, email and the time you choose.
- Resend, which sends the app's emails: sign-in links, check-in reminders and plan updates.
- Loom, if your coach sends you a video.
Some of these companies are based outside the UK. Where your information is processed outside the UK, it's protected by the safeguards UK law requires, such as approved data transfer agreements.
How we keep it safe
Your information is encrypted in transit, and only your coach's account can open client records. Your questionnaire is only reachable through your own private link. While you fill it in, your answers are also kept on your device so you don't lose them. They're removed from your device once sent. Progress photos are stored privately: only you and your coach can open them, through links that expire after 10 minutes, and location data is removed from each photo before it's uploaded.
How long we keep it
We keep your information while you're a client and for up to 2 years afterwards, in case you return or have questions about your coaching. After that it's deleted. Carb Load Calculator details are kept for up to 2 years after your race. You can ask us to delete it sooner at any time.
Your rights
You can ask us to:
- give you a copy of the information we hold about you,
- correct anything that's wrong,
- delete your information,
- limit or stop how we use it, or withdraw your consent,
- send your information to you or another service in a common format.
Email jheaneynutrition@gmail.com. We'll reply within one month. If you're unhappy with how we've handled your information, you can complain to the Information Commissioner's Office at ico.org.uk.
Cookies
We don't use advertising or tracking cookies. We use two functional cookies: one keeps you signed in, and if you arrive through someone's referral link, one remembers their referral code for 60 days so they're credited if you join. That cookie holds only the code, nothing about you. Your questionnaire draft is stored on your device, not in a cookie.
Changes
If we change this policy we'll update the date at the top, and tell current clients about anything important.
