Abstract: The disclosed technology provides for secure storage and usage of data at an electronic device. A device may include a hardened data manager that securely stores data associated with users of the device and/or another device. An application that does not have access to the securely stored data can still use the securely stored data by requesting that another system process at the device perform operations on the securely stored data and/or one or more updates to the securely stored data. For example, an application can request rendering of an avatar of a user. A rendering engine, separate from the application, can obtain securely stored base data from the hardened data manager, obtain updates to the securely stored base data, and render the avatar using the updates to the securely stored base data, without exposing the securely stored base data to the application.
