EnergyKit data security
iCloud and iCloud Keychain securely synchronize EnergyKit data between a user’s Apple devices. End-to-end encryption through the entire process ensures the data isn’t accessible to anyone, even Apple.
Users can control the access of their energy data in the system Privacy settings. When apps want to access energy data, the operating system prompts a user for approval, in a way that’s similar to Home data, Contacts, Photos, and other iOS, iPadOS, and macOS data. If a user approves the prompt, apps can access the names of Homes, Electricity Guidance, and other home information. In addition, EnergyKit can receive electricity usage data from authorized apps.
Local data storage
EnergyKit stores data on a user’s Apple devices. The framework secures the data using the Data Protection class Protected Until First User Authentication and a data vault. However, local backups exclude EnergyKit data.
