SharedStorage
Deprecated
To be removed
This feature is pending removal from browsers. Using it now may lead to broken functionality in future updates. Following the announcement that Chrome will maintain its current approach to third-party cookies, Chrome decided to withdraw certain Privacy Sandbox features including the shared storage.
Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.
