Who we are
Online Personal Training UK (also called Online PT UK and OPTUK Coach) is a trading name of Audio.Visual.Digital, a sole trader business based in the UK. We are the “data controller” for the personal information described here, which means we decide how it’s used and we’re responsible for looking after it.

What we collect
Your account. Your email address and a password. Your password is stored scrambled (hashed) by our database provider, so we can never see it.
About you. What you tell the coach when you set up: first name, biological sex, age, height, weight, goal weight, active calories, average daily steps, the days you can train and how often, your goal (fat loss, muscle gain or maintenance), plan length, pacing, check-in day, and any events you add (a date and a short description, such as “Sarah’s wedding”).
Your progress. Food you log (calories and protein), your daily check-ins (steps, active calories and morning weight), weekly reviews, week plans and your chat with the coach.
Payments. Payments are handled by Stripe. We never see or store your full card details. We receive the plan you bought, the amount, the date and a Stripe reference.
Technical information. Our hosting and database providers keep short-term logs (such as IP address, browser type and time of visit) to keep the service secure and working.
Your health information
Your weight, body measurements, activity and what you eat count as health information, which UK data protection law treats as a special category that needs extra protection.
We only use it to run your plan: to calculate your calorie, protein and step targets, and to review your progress each week. We ask for your explicit consent to this when you create your account. You can withdraw your consent at any time by asking us to delete your account, but we can’t provide the service without this information.
Your targets are worked out automatically from what you enter. This doesn’t lead to any decision with a legal or similarly significant effect on you, and you can always ask us about how a number was calculated.
Why we use your information
| What we do | Legal basis |
|---|---|
| Create your account and run your coaching plan | To provide the service you signed up for (contract) |
| Use your health information to calculate and review your targets | Your explicit consent |
| Take payment and keep records of purchases | Contract, and our legal duty to keep tax records |
| Send emails about your account, such as confirming your email address | Contract |
| Keep the service secure and fix problems | Our legitimate interest in running a safe, working service |
We don’t sell your information, we don’t show you adverts, and we don’t send marketing emails. If that ever changes, we’ll ask for your permission first.
Who we share it with
We use a small number of trusted providers to run the service. They only process your information on our instructions:
- Supabase — your account and coaching data (stored on servers in Ireland)
- Stripe — payments
- Netlify — hosts the website
- Google Fonts and esm.sh — deliver the font and parts of the app’s code to your browser, so they see your IP address when the page loads
Some of these providers are based in, or use servers in, the United States. Where your information leaves the UK, it’s protected by UK government adequacy rules or by approved data protection contracts.
We may also share information if the law requires it.
How long we keep it
- Your account and coaching data — for as long as you have an account. If you ask us to delete your account, we’ll delete it within 30 days.
- Purchase records — six years, because UK tax law requires it.
- Technical logs — for the short periods our providers set.
Cookies and browser storage
We don’t use advertising or analytics cookies, and we don’t track you around the web.
The app saves a small amount of information in your browser that it needs in order to work: keeping you logged in, keeping a copy of your progress so it loads quickly and works offline, and remembering a plan you picked from a link. Because this is strictly necessary, it doesn’t need a cookie banner.
Stripe sets its own cookies on its checkout page to prevent fraud.
Keeping it safe
Everything travels over an encrypted connection. Your coaching data sits in a database where each account can only ever read its own information, and only our payment system can record a purchase.
Your rights
Under UK data protection law, you have the right to:
- ask for a copy of the information we hold about you
- ask us to correct anything that’s wrong
- ask us to delete your information
- ask us to limit how we use it, or object to how we use it
- ask for your information in a format you can take elsewhere
- withdraw your consent at any time
Email [email protected] and 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 (ICO) at ico.org.uk or on 0303 123 1113. We’d appreciate the chance to put things right first.
Age
Online PT UK is for adults aged 18 and over. We don’t knowingly collect information from anyone younger.
Changes to this policy
If we change how we use your information, we’ll update this page and change the date at the top. If the change is significant, we’ll let you know by email or in the app.
