In what ways can brands proactively communicate with customers about the data they collect and how it is used in order to build trust and maintain transparency in their personalization efforts?

Brands can proactively communicate with customers by being transparent about their data collection practices through clear and easily accessible privacy policies. They can also provide opt-in options for customers to choose the type of data they are comfortable sharing. Additionally, brands can regularly update customers on how their data is being used through email newsletters or notifications. By being open about their data practices and actively seeking customer consent, brands can build trust and maintain transparency in their personalization efforts.
