Cross-Platform App CommunicationApple and Google have both worked to create APIs for exposure notifications that work together so iPhone and Android smartphones can interface with one another and you'll receive notifications if exposure happens even if the person you've been in contact with has an Android smartphone.
Exposure Notification Opt-In
In the iOS 13.5 Exposure Notification is a privacy setting that is off by default, and using the feature requires users to download an app and consent to sign up for the exposure notification system.
If you do, at some point, get COVID-19, there's a separate consent process for anonymously alerting people that you've been in contact with. The app needs express consent to inform others of the diagnosis, and nothing happens automatically.
In other words, it is opt in at the users choice at every level, and also anonymously, using on-device generated cryptographic keys, that are only connected on the cloud. Permissions are also the user’s choice. It is OFF by default, and the API only becomes active when the user downloads an App, activates it voluntarily, that detects nearby persons with a similar App and exchanges keys. None of these data are shared with either Apple or Google.
Want to bet it doesn't become mandatory? The Cloud is lousy with all sorts of back-doors and taps, ISP's and otherwise, government requested and sanctioned.
