Your have the right to demand a confirmation on whether we do or did process your PII. If we did process PII connected to your person, you have the right to be informed which PII we processed, as well as for why we did process this data, and in which way we processed it.

Art. 16 DS-GVO – Right to correction

You have the right to demand the immediate correction of incorrectly stored PII. Under consideration of the reason of processing of the collected PII, you also have the right to demand the completion of incomplete datasets, which also includes demanding additional annotations.

Art. 17 DS-GVO – Right to deletion

You have the right to directly transfer this data to another service provider without our interference as long as this is technically feasible.

Art. 21 DS-GVO – Right to objection

You have the right to object to our processing of your PII, if this processing takes place for our own justified interests, serves the fulfillment of public interests, or in the exercise of official authority vested in the controller.

If you object to processing, your PII will no longer be processed, except if we do offer protected reasons for the processing of this data that outweight you rights and interests, or if the processing is necessary to claim, exercise, or defend legal claims.

  • Art. 6 Abs. 1 lit. b EU-Datenschutzgrundverordnung (DSGVO): If we collected PII to fulfill a contract or agreement;
  • Art. 6 Abs. 1 lit. c EU-Datenschutzgrundverordnung (DSGVO): If we are legally required to collect this PII;
  • Art. 6 Abs. 1 lit. f EU-Datenschutzgrundverordnung (DSGVO): If we need to collect this data to fulfill the legitimate interests of the service we provide, or a third party. In these cases, you interests, basic rights, and basic freedoms must not outweight these legitimate interests.

If PII is processed based on Art. 6 Abs. 1 lit. a or f you can object to processing of your data at any time.
