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

A method comprising:

• receiving, by computing hardware via a first computing device, a session request comprising a request to access computing functionality on the first computing device;
• responsive to the session request, causing, by the computing hardware, the first computing device to display a computer-readable indicium, wherein the computer-readable indicium comprises:
• an indication of the session request;
• and
• navigation instructions to navigate to a consent interface for the computing functionality;
• receiving, by the computing hardware via a second computing device, an indication of an interaction with the computer-readable indicium;
• responsive to the interaction, causing the second computing device to follow the navigation instructions and display the consent interface, wherein the consent interface comprises a mechanism for providing privacy-related user consent preferences for the computing functionality to process personal data;
• receiving, by the computing hardware via the mechanism on the consent interface displayed on the second computing device, the privacy-related user consent preferences;
• and
• responsive to receiving the privacy-related user consent preferences:
• detecting, by the computing hardware, a change to the privacy-related user consent preferences
• automatically transmitting, by the computing hardware, the changed privacy-related consent preferences from the second computing device to the first computing device based on a selection of a second selectable mechanism on the second computing device;
• and
• causing, by the computing hardware, storage of the changed privacy-related user consent preferences on the first computing device so that the privacy-related user consent preferences are applied with respect to the computing functionality processing the personal data on the first computing device based on the selection of the second selectable mechanism on the second computing device.

A non-transitory computer-readable medium storing computer-executable instructions that, when executed by computing hardware, configure the computing hardware to perform operations comprising:

• receiving, via a first computing device, a session request comprising a request to access a particular service on the first computing device;
• responsive to the session request, causing the first computing device to display a code that identifies the session request and navigation instructions;
• receiving, from a second computing device that has followed the navigation instructions, the code;
• responsive to receiving the code, causing the second computing device to navigate to and display a consent interface for the particular service, wherein the consent interface comprises a mechanism for providing privacy-related user consent preferences for the particular service to process personal data;
• receiving, via the mechanism on the consent interface displayed on the second computing device, the privacy-related user consent preferences;
• and
• responsive to receiving the privacy-related user consent preferences:
• detecting, by the first computing device, a change to the privacy-related user consent preferences
• automatically transmitting the changed privacy-related consent preferences to the first computing device based on a selection of a second selectable mechanism on the second computing device;
• and
• storing the changed privacy-related user consent preferences on the first computing device so that the privacy-related user consent preferences are applied with respect to the particular service processing the personal data on the first computing device.
