As of now RepoTracker is a client-only application and there is no backend or database. This might change in the future, e.g. to enable sync between devices, but currently all data that you add to RepoTracker is stored exclusively in your browser.

Sign in with GitHub is only necessary to leverage an increased API request budget available to authenticated GitHub users (1500 instead of 60 requests per hour for REST and a similar metric for the GraphQL endploints).

RepoTracker uses privacy-friendly analytics provided by Plausible , who host all their services in the EU. Please consult their privacy policy and their data policy for more information.
