3.10Processing of videos in which third parties appear (coaches)Images and videos of third parties provided by the user, associated metadataPerformance of a contract (art. 6.1 b)Until the user deletes the content or requests its removal

1 Once the indicated periods have elapsed, the data will be blocked and retained solely for the handling of legal liabilities, after which they will be deleted or irreversibly anonymized. Data that has been anonymized or aggregated will fall outside the scope of the GDPR and may be retained indefinitely for statistical, research, or service improvement purposes.

Note: when a user (for example, a coach) uploads videos in which third parties appear, the user uploading the video declares that they have an appropriate legal basis and, where applicable, the necessary consent. Any person who considers that their image or data has been processed improperly may exercise their rights by writing to rgpd@fitizens.io.

Certain functionalities of the Service (for example, technique analysis through video and the generation of metrics) require the processing of data belonging to special categories (art. 9 GDPR) —including biometric and activity parameters captured by means of integrated physical sensors (for example, accelerometers, heart-rate monitors, optical sensors, cameras, or other equivalent devices)—.

For this reason, during the first opening of the App (or during the sign-up process), the Data Subject is asked for their explicit consent by means of a checkbox or equivalent mechanism. If the Data Subject does not grant such consent, it will not be possible to use the functionalities of the Service that require such processing (which may prevent use of the App).

The withdrawal of consent does not affect the lawfulness of prior processing and may be carried out at any time from the profile within the App or by communication to the DPO; however, withdrawal may imply the impossibility of continuing to provide the Service.

4 bis. Anonymized data and use for improvement and research purposes

FITIZENS applies anonymization and aggregation techniques in accordance with industry best practices and the guidelines of the AEPD and the EDPB, ensuring that the resulting information does not allow for the direct or indirect identification of users.

Anonymized or aggregated data may be used for statistical, research, and development purposes, and for the improvement and optimization of the functionalities and technologies of our Services.

5. Recipients and data processors

  1. FITIZENS will not transfer data to third parties except where legally required or with the prior consent of the Data Subject.
  2. Providers belonging to the categories in the table indicated below access the data as data processors (art. 28 GDPR).
  3. The Controller has formalized (or will formalize before any processing) the corresponding processor agreements (art. 28 GDPR) and has carried out (or will carry out) Transfer Impact Assessments (TIA) where appropriate, in accordance with EDPB Guidelines 05/2021.
