Confidentiality and GDPR

GDPR: Strong

You process special category personal data (health) and sometimes data for genetic research. Software for diagnostic use is an in vitro diagnostic medical device: check whether the algorithm is CE-marked under the IVDR for your exact application and tissue type. Many apps are 'research use only'. Choose providers with ISO 27001 and ISO 13485, a data processing agreement and clear data location (EU hosting or on-premise). Also ask whether your slides are used to train models. Under the EU AI Act, medical AI falling under the IVDR is classed as high-risk. Validate every algorithm locally on your own scanner and stains before using it in routine practice.

Data is held in the EU by default (Paris cloud, plus EU regions via Bedrock/Azure/Vertex). Open models run entirely in your own environment. Pro/Team/Enterprise and API do not train on your data.

Rule of thumb Use the business variant with a data processing agreement, and keep a human in the loop for decisions that matter.
