Privacy Policy

Who we are

Strength Lab LDN is a strength and performance coaching studio operated by SD Performance Limited. This policy explains what information the Strength Lab LDN app collects, how we use it, and the choices you have. You can reach us at sam@strengthlabldn.com.

About the app

The app is for members and coaches of Strength Lab LDN. You need an account with the studio to sign in. It shows your programme, sessions and progress, and connects to the systems we use to run the studio.

Information we collect

• Account details such as your name, email and sign-in PIN.
• Training data such as your programmes, session logs, assessments, readiness check-ins and habits.
• Wearable data, only if you choose to connect a device, such as recovery, sleep and activity from providers including Whoop, Oura, Fitbit and Garmin.
• Phone health data, only if you choose to sync it in the Strength Lab app: sleep (including sleep stages), heart rate variability, resting heart rate, heart rate, respiratory rate, blood oxygen, steps, active energy, VO2 max and wrist temperature from Apple Health (iOS) or Health Connect (Android). The app only reads this data — it never writes to Apple Health or Health Connect.
• Booking and membership information from our studio booking system.
• Basic usage and error information that helps keep the app working.

How we use your information

We use your information to deliver coaching, show your programme and progress, calculate your readiness, run rewards, manage your bookings, and improve the service. We do not sell your data and we do not use it for advertising.

Health data from Apple Health, Health Connect or a connected wearable is used for one purpose: to calculate your daily readiness and help your coach adjust your training. It is stored securely in our database, is visible only to you and your coaching team, is never used for advertising or shared with third parties for their own purposes, and you can stop syncing at any time in the app (Wearables) or in your phone's Health settings. Ask us to delete it and we will.

Who we share it with

We share data only with service providers who help us run the app on our behalf: our hosting and database provider, our studio booking system, any wearable provider you choose to connect, and our email delivery service. They act only on our instructions.

Legal basis (UK GDPR)

We process your data to perform our coaching agreement with you, and on the basis of your consent for health data and any marketing messages.

Your rights

You can access, correct, export or delete your data at any time. You can manage your consents and request deletion inside the app under Privacy, or by emailing us at sam@strengthlabldn.com.

Keeping your data

We keep your data while you are a member and for a reasonable period afterwards, then delete or anonymise it. Your data is stored securely and encrypted while in transit.

Children

The app is intended for adults who are members of the studio and is not aimed at children under 16.

Changes and contact

We may update this policy from time to time. The date at the top shows the latest version. If you have any questions, contact us at sam@strengthlabldn.com.
