In the past, third-party storage (like cookies) was not partitioned by the website. This meant that a third-party embed could access its storage across all websites where it appeared, potentially enabling widespread tracking of user activity.
Storage Access introduces a more privacy-conscious approach. While embeds can still access their unpartitioned storage, they can only do so when certain conditions are met. This means that users have greater control over their data and can choose which third-party embeds are allowed to access their information.
68% of people report that they are concerned about their privacy online. The Storage Access API addresses this concern head on by providing a low-friction way of asking the user if sharing their data across sites should be allowed. This prompt appears following a user gesture, surfacing right when a user intends to carry out an action with your service.
Storage Access prompts are an opportunity to build trust with your users by demonstrating that you value transparency and that users are in control, creating a more positive experience with your product.
