Part A - The Contributor's personal data

10.2. The Company acts as Controller of the personal data of the Contributor that it processes in order to operate the Platform, administer the Account, allocate and review Tasks, calculate and make payments, verify identity, prevent fraud, comply with its legal obligations, and establish, exercise or defend legal claims.

10.4. The categories of personal data processed, the recipients, the retention periods, the international transfers and the Contributor's rights as a Data Subject are described in the Privacy Notice, which forms part of this Agreement.

10.5. Because Contributors may be located in any country, the Contributor's personal data may be transferred internationally. Where required, the Company applies appropriate safeguards for such transfers in accordance with applicable data protection law.

Part B - Personal data contained in Input Data (Annotation Tasks)

10.6. Input Data provided for Annotation Tasks may contain personal data.

10.11. The legal basis for the Company's processing of the Collected Data is the performance of this Agreement and, where applicable and separately obtained, the Contributor's consent. Where the Collected Data includes Special Categories of Data, including biometric data, the Company relies on the Contributor's explicit consent, obtained separately at the point of collection.

10.12. The purposes of processing the Collected Data include the creation, curation and supply of datasets and the development, training, validation, benchmarking and improvement of artificial intelligence and machine learning systems, including the supply of such datasets to the Company's clients.

10.13. The Contributor may withdraw consent at any time, as easily as it was given, by the means indicated on the Platform.

The Contributor acknowledges that, following withdrawal, the Company may be unable to retrieve, isolate, alter or delete Collected Data that has already been incorporated into a dataset, delivered to a client, or used to train or develop a model, and that the Company may continue to process such already-incorporated data where it has a separate lawful basis for doing so.
