Information sources for an App

Our research into an App is based on the following information sources, to the extent they are available:

• Information self-asserted by App Creators, such as in public communications (e.g. press releases, website, app store listing) describing their App.

• Information inferred by third parties, such as by direct examination of the running App, review of publicly available code, reverse engineering, or review of assertions by App Creators.

• Information from third-party audits, in which a qualified independent third-party entity has the full cooperation of the App Creators, and full access to all relevant people and information, in order to assess all aspects of the App.

We consider third-party audits the best source for reliable information about an App. Relevant parties include experts in epidemiology, public health, technology, operations, governance and civil rights.
