Privacy Policy
Last updated: 22 June 2026
BeeStrong App is a workout tracking application for athletes, fitness enthusiasts, and personal trainers. This Privacy Policy explains what personal data we collect, how we use and share it, how long we retain it, and the rights available to you under the UK General Data Protection Regulation (UK GDPR) and, where applicable, the EU General Data Protection Regulation (EU GDPR).
If you want to request deletion of your account and data, you can do so in the app (Profile > Delete account and data) or without the app at beestrongapp.com/en/delete-account/. See section 12 for details.
1. Who controls your data
BeeStrong App is operated by Dariusz Sztejnagiel, an individual based in the United Kingdom, who acts as the data controller for the purposes of UK GDPR. For privacy questions or requests, contact support@beestrongapp.com.
2. Data we collect
Depending on the features you use, BeeStrong App may collect or process the following information.

Body measurements and progress photos
You may voluntarily provide body weight, body fat percentage, waist, chest, arm, thigh, and other measurements; measurement notes; progress photographs; and photograph dates and descriptions.
This information may be considered health-related or special category data under applicable data protection laws. We process it only when you choose to enter, upload, sync, or share it for the purpose of using the relevant BeeStrong features. You can use BeeStrong without entering body measurements or uploading progress photos.
Coach Mode data
- Coach-client invitations and relationships
- Assigned workout programs
- Client workout and measurement progress
- Coaching notes and check-ins
- Coach ratings and reviews
- Information submitted in coaching applications, such as name, age, training experience, goals, and preferred number of workouts per week

A coach can access client information only through an accepted coach-client relationship and the permissions provided by the app.
Friends and social features
- Friend invitations and relationships
- Display names used in social features
- Messages exchanged between users
- Messages exchanged between coaches and clients
- Shared workout templates
- Challenge invitations and results

Information you intentionally share with another user will be visible to that user.
AI Coach data
AI Coach is an optional feature available to eligible users. When you use AI Coach, a request may include your display name, selected app language, current and best workout streak, details of up to your seven most recent workouts, exercise names, weights, repetitions, duration, training volume, messages and questions you submit, and the current AI Coach conversation history.
Requests are sent through a BeeStrong Supabase Edge Function to Groq, which provides AI inference using the GPT OSS 120B model through an OpenAI-compatible API. Data is sent only when you actively use AI Coach. Groq processes request data according to its applicable service terms. BeeStrong does not use AI Coach conversations to train its own AI models. AI-generated content is general fitness information, not medical advice.
Push notification data
- Firebase Cloud Messaging token
- Web Push subscription endpoint and authentication keys
- Device platform
- Notification preference
- Limited browser or device User-Agent information
- Notification delivery information
This information is used only to register the device and deliver notifications. You can disable notifications in BeeStrong or through your device settings.
Purchase and subscription data
Purchases in the Android app are processed through Google Play Billing. BeeStrong does not receive or store your full payment card information. Google processes payment details according to its own privacy policy. We may process:
- Google Play product identifier
- Purchase token and order identifier
- Product type
- Purchase and acknowledgement status
- Subscription expiry date
- Automatic renewal status
- Technical response received from Google Play

Local device data
BeeStrong is designed to work offline. The app may store workouts, templates, preferences, language and theme settings, AI Coach notes saved by you, notification history, cached application files, and temporary offline synchronization data locally on your device. Clearing browser storage or application data may permanently remove information that has not been synchronized.
Technical and website data
The BeeStrong website may process limited technical information necessary for security, delivery, and analytics, such as IP address, browser and device type, requested pages, approximate country or region, and security and diagnostic information. The website uses Cloudflare services, including Cloudflare Pages and Cloudflare Web Analytics.

4. Legal bases for processing
- Contract: to provide the BeeStrong service and features requested by you.
- Legitimate interests: to secure the service, prevent abuse, maintain reliability, and improve app performance.
- Consent: for optional features such as notifications, progress photos, AI Coach, and voluntary sharing where consent is required.
- Legal obligation: to retain records or respond to lawful requests where required by law.
Where body measurements or progress photos are treated as special category health data, we rely on your explicit consent where required by law. You may withdraw consent by stopping use of the relevant feature, deleting the relevant data, disabling sharing or notifications, or contacting us. Withdrawal does not affect processing that was lawful before consent was withdrawn.
5. Cloud storage and synchronization
If you create an account or use cloud features, selected information may be stored and synchronized through Supabase. BeeStrong uses Supabase for authentication, database storage, file storage, cloud synchronization, realtime features, and Edge Functions. BeeStrong Supabase infrastructure is hosted in the European Union, in Frankfurt, Germany. Data is encrypted in transit using HTTPS/TLS. Some information may remain only on your device unless you enable or use a feature that uploads it.
6. Sharing with coaches and other users
If you accept a coach invitation, the coach may be able to access workout data, measurements, assigned programs, progress information, and other information required to provide coaching services. Only accept invitations from coaches you trust. Messages, shared templates, challenges, and other information you send to another user will be accessible to the intended recipient. BeeStrong is not responsible for how another independent user uses information that you intentionally share outside the functions and permissions provided by the service.
7. Service providers
- Supabase Inc. — authentication, database, file storage, synchronization, realtime services, and Edge Functions.
- Groq, Inc. — optional AI Coach inference.
- Google LLC / Google Play — Android distribution, purchases, subscriptions, purchase verification, and Firebase Cloud Messaging.
- Cloudflare, Inc. — website hosting, delivery, security, and privacy-friendly website analytics.
These providers process information only for the relevant services and according to their contractual obligations and privacy terms.
8. International data transfers
BeeStrong account and workout data is primarily processed in the European Union through Supabase infrastructure in Frankfurt and may also be accessed or administered from the United Kingdom. Some service providers may process information outside the United Kingdom or European Economic Area. Where required, international transfers are protected using appropriate safeguards, such as UK or EU adequacy regulations, Standard Contractual Clauses, the UK International Data Transfer Addendum, or other safeguards permitted by applicable law.
9. Cookies and local storage
BeeStrong uses local storage and similar device storage for essential app functions, including offline functionality, authentication sessions, preferences, cached files, and locally saved workout data. The BeeStrong website does not use advertising cookies or cross-site behavioural tracking. Cloudflare may process necessary technical information to provide security, content delivery, and analytics.
10. Biometric authentication
On supported Android devices, BeeStrong may allow you to protect access using device biometrics. Biometric authentication is performed locally by the Android operating system. BeeStrong does not receive or store your fingerprint, facial image, biometric template, or other raw biometric data. BeeStrong stores only a local preference indicating whether biometric protection has been enabled.
11. Data retention

- Workout, template, program, and measurement data: until deleted by you or until the account is deleted.
- Progress photos: until deleted by you or until the account is deleted.

Backups may retain deleted information for a limited period before being securely overwritten.
12. Account and data deletion
You can request deletion from within BeeStrong through: Profile > Delete account and data > Delete account and cloud data. You can also request deletion without using the app at beestrongapp.com/en/delete-account/ or by contacting support@beestrongapp.com. We may ask you to verify ownership of the account before processing an external deletion request. Deleting your account removes or anonymises personal information associated with the account, except information that must be retained for legal, accounting, fraud prevention, dispute resolution, or security purposes. Requests will be handled without undue delay and normally within 30 days. Deleting the app from your device does not automatically delete your cloud account.

- Correct inaccurate information
- Request deletion
- Restrict processing
