# Cancellation Right Given the particular nature of the Product subject to the transaction, which assumes an instantaneous execution, the Purchaser acknowledges that he/she is informed that his/her right of cancellation cannot be exercised. The supply of digital content not provided on a physical medium and whose execution has begun after prior agreement requires a voluntary waiver by the consumer of his right of cancellation. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
