I don't know much about these contact tracing apps.
If you download the app does it start tracking you movements right away? If so who is getting this information?
Info for Apple and Google app
Apple Inc. and
Google released the first versions of their Covid-19 contact-tracing tools to public health organizations on Wednesday so the agencies can start building applications ahead of the system’s launch in mid-May.
The tool set is a combination of software updates for iOS and Android, and software development kits to help developers build and test their apps. Apple released an early beta version of its software update that incorporates the technology, iOS 13.5, while Google is rolling out an update via its Google Play app store.
The first phase of the system will let health agencies build apps that allow a person who tests positive for Covid-19 to input their diagnosis. The system will then use Bluetooth technology to learn who the person has come into contact with and then notify those people of a possible exposure.
Apple released Xcode 11.5, a new version of its software development kit on Wednesday, while Google is providing an update of its SDK to select developers.
The companies also said that on Friday they will release sample code to help developers understand how the exposure-notification system will work, along with more information on which types of apps will be allowed.
Apple, Google Release Virus Contact-Tracing Tools to App Makers
In a few weeks, your smartphone may tell you that you've been close to someone infected by the coronavirus and that you may need to isolate yourself.
By mid-May, Apple and Google will offer a mobile software tool that will let iPhones and Android devices talk to each other and allow digital
contact tracing, which tracks those with infections and alerts others who have been in close contact.
Apple and Google will release an API, or application programming interface, that helps a smartphone anonymously detect when it's been near the smartphone of someone who has reported they have the virus.
That API will let software developers build apps — distributed by public health authorities — that could alert users to potential exposures to COVID-19.
Digital contact tracing doesn't diagnose infections; it only tells users if they've encountered someone who is infected. While other companies are building contact tracing apps, the Apple/Google partnership could greatly expand tracing, since:
