Finnish Post has decided to start using your data for service planning and development. What for? Well of course for "personalized content and targeted advertising". This is opt-in by default.
"My data may be used for service planning and development, as well as for delivering personalized content and targeted advertising using profiling.
Profiling refers to automated processing of personal data where the information is used to evaluate personal characteristics, such as interests or service usage. The purpose of profiling is to enhance the customer experience and ensure that the customer receives relevant and interesting recommendations and services."
Notably for some reason this is separate from "Marketing consents" and is enabled by default.
