  • Art. 9(2)(a) GDPR, where body, fitness, activity, health-related, or nutrition data may qualify as special-category data and processing is based on your separate explicit consent
  • Art. 6(1)(f) GDPR, where processing is necessary for security, troubleshooting, and reliable technical operation
  • Art. 6(1)(c) GDPR, where processing is necessary to comply with legal obligations

Acceptance of the Terms and Privacy Policy is separate from consent to process body, fitness, activity, health-related, and nutrition data. Before using tracking features, you may be asked to provide separate explicit consent for this processing.

Providing body, fitness, training, and nutrition data is voluntary. Some app features may not work or may be limited if you do not provide this data.

6. Body, Fitness, and Nutrition Data

The app processes data such as weight, body metrics, nutrition, training, and activity only for personal tracking and progress display.

This data is not used for medical diagnosis, medical treatment, or automated medical decisions.

You should not use the app as a substitute for medical advice or professional healthcare.

7. Registration and User Account

To use the app, you need a user account. Account creation may require an invitation. During invitation request, registration, and account use, we process data such as your name, email address, invitation status, and password.

The app is intended for users who are at least 16 years old. Users under 16 may not create an account or use the app.

Passwords are not stored in plain text.

Your email address is used for login, important account functions, password reset, and security-related messages.

8. Password Reset and Email Delivery

If you request a password reset, we send an email containing a password reset link.

We use Resend for transactional email delivery, including password reset emails and invitation emails.

We may use Brevo to manage the invitation waitlist and double opt-in subscription confirmation before access is granted.

Resend
Resend, Inc.

This may include your name, email address, message content, date and time of the message, and related technical or account information where needed to handle your request.

Contact and support messages may be reviewed by the app administrator for support, troubleshooting, security, documentation, and follow-up purposes.

The legal basis is Art. 6(1)(b) GDPR where the request relates to your user account or use of the app, and Art. 6(1)(f) GDPR where processing is necessary for support, documentation, troubleshooting, security, or legitimate communication handling.

Contact and support messages are stored only as long as necessary to handle the request, document the communication, resolve follow-up questions, or protect legitimate interests.

The app is hosted on Heroku.

The app database is also operated through Heroku or Heroku-managed infrastructure, where applicable.

11. Content Delivery Network and Frontend Resources

When you access the app, your browser may connect to jsDelivr servers. For this purpose, technical data such as your IP address, browser information, requested file, referrer URL, and date and time of access may be processed.

This processing is necessary to deliver the app interface reliably and securely. The legal basis is Art. 6(1)(f) GDPR, our legitimate interest in providing a secure, stable, and functional app.

15. Transfers Outside the EU/EEA

Some service providers may process personal data outside the European Union or European Economic Area. Heroku and Resend are providers based in the United States. Brevo / Sendinblue GmbH is based in Germany and may use subprocessors or infrastructure outside the EU/EEA where legally permitted. If you consent to analytics, Google Analytics may involve processing by Google Ireland Limited and Google LLC, including possible processing in the United States. jsDelivr / Prospect One is based in Poland but may use globally distributed CDN infrastructure.

Such transfers take place only where an appropriate legal basis exists, such as:

  • an adequacy decision by the European Commission
  • Standard Contractual Clauses
  • additional contractual and technical safeguards
  • another legally permitted basis

16. Storage Period

Personal data is stored only as long as necessary for the purposes described in this Privacy Policy.

Account, fitness, body, training, and nutrition data is generally stored as long as your user account exists.

Invitation requests and invitation records are stored only as long as necessary to manage access, document subscription confirmation, prevent abuse, and protect legitimate interests.

Contact and support messages are generally stored for as long as necessary to handle the request, document the communication, resolve follow-up questions, or protect legitimate interests. They may be deleted earlier if they are no longer needed.

After account deletion, personal product data is deleted or anonymized unless legal obligations or legitimate reasons require further storage.

Technical logs are stored only for a limited period where necessary for security, troubleshooting, or operation.

Backups are retained for a limited period, typically 7-30 days. Deleted data may remain in encrypted backups until backup rotation. Backups are not used for normal product processing.

17. Account Deletion

You can request deletion of your account.

After your request, your account is scheduled for deletion. Final deletion takes place after a 30-day waiting period, unless you cancel the deletion request before that period ends.

During the pending deletion period, normal access to the app may be restricted.

After the waiting period, personal product data is deleted or anonymized, including:

  • body data
  • weight entries
  • training data
  • activity data
  • running data
  • step counts
  • nutrition entries
  • goals

A minimal deletion record may be retained, such as the time of request, time of deletion, and a reduced technical reference, where this is necessary for documentation, security, or legal defense.

18. Data Export

You may request or download a copy of your stored data where this feature is provided.

The export may include:

  • profile data
  • body data
  • weight entries
  • training data

20. Withdrawal of Consent

Where processing is based on consent, you may withdraw your consent at any time with effect for the future.

If you withdraw consent for body, fitness, activity, health-related, or nutrition data, tracking features may no longer be available. Withdrawal does not affect the lawfulness of processing carried out before withdrawal.

The lawfulness of processing before withdrawal remains unaffected.

21. Required Data

Some data is required to use an account, especially your email address and password.

Other data, such as weight, nutrition, training, goals, or body data, is voluntary. Without this data, some features may not work or may be limited.

This Privacy Policy may be updated if app features, service providers, or legal requirements change.
