Initiating data privacy pipelines using reusable templates

Implementations are directed to developing and facilitating a data collaboration using a data collaboration tool that bundles data pipelines and governing contracts into a data collaboration app. The data collaboration tool may include an authoring mode and may include an electronic canvas that visually represents all contracts and pipelines of the data collaboration app on a single canvas and visually represents traceability from the contracts to the pipeline elements they enable. A developer may use authoring mode to develop a template app that includes placeholder elements, including a reference to an anonymous placeholder participant. The template app may be shared, and a recipient may invite data collaborators to fill in the placeholder elements and deploy the app, enabling the data collaborators to trigger the data pipelines to execute in a data trustee environment to generate insights from each other's assets without exposing the assets to the collaborators or the developer.
