Data processing systems and methods for synching privacy-related user consent across multiple computing devices

A consent extension system for extending one or more privacy-related consents to process personal data for a particular data subject from a first computing device to a second computing device, the system comprising:

• one or more processors;
• and
• computer memory, wherein the consent extension system is configured for:
• receiving, from the particular data subject, the one or more privacy-related consents to process personal data on the first computing device;
• receiving a request to extend the one or more privacy-related consents to the second computing device;
• and
• in response to receiving the request, automatically facilitating the extension of the one or more privacy-related consents to cover the second computing device.

A computer-implemented data processing method for extending at least one privacy-related consent for an entity to process one or more pieces of personal data associated with a user of a first computing device to a second computing device, the method comprising:

• receiving, from the user via the second computing device, a request to initiate a transaction between the entity and the user, the second computing device not being associated with any privacy-related consent data for the user;
• at least partially in response to receiving the request, providing a computer-readable indicium on a consent extension interface on the second computing device;
• receiving authentication of the computer-readable indicium from the first computing device, the first computing device being associated with stored privacy-related consent data for the user;
• and
• at least partially in response to receiving authentication of the computer-readable indicium from the first computing device, associating the second computing device with the stored privacy-related consent data for the user so that the privacy-related consent data applies to the second computing device.

A computer-implemented data processing method for extending privacy-related consent for an entity to process one or more pieces of personal data associated with a user of a first computing device to a second computing device, the method comprising:

• receiving, from the user via the first computing device, privacy-related consent data corresponding to consent for the entity to process one or more pieces of personal data associated with the user;
• storing the privacy-related consent data as first device consent data, the first device consent data comprising an association of the first device consent data with the user;
• providing a computer-scannable code on a consent extension interface on the second computing device;
• receiving authentication of the computer-scannable code from the first computing device;
• in response to receiving authentication of the computer-scannable code from the first computing device, facilitating the communication of the first device consent data to the user;
• after facilitating the communication of the first device consent data to the user, receiving a request to associate the first device consent data with the second computing device as second device consent data;
• and
• in response to receiving the request to associate the first device consent data from the user with the second computing device as second device consent data, storing the first device consent data as second device consent data, the second device consent data comprising an association of the second computing device consent data with the user.
