While not directly intentional, it kind of defeats the purpose of Iridium if you are signed into Google and report everything to them. From a technical point of view, signing in to Google requires a Google API key, client ID and client secret. Iridium does not ship with one — therefore it does not work. If you insist to use Google sign-in, check Chromium API keys and follow the instructions for
Providing Keys at Runtime.
This helps the development team to find issues with potential privacy problems. The development marks all external URLs they find in the Chromium source code with a “trk:” prefix. Additionally, all “trk:” URLs receive a number which makes tracing the code easier, i.e.
git grep trk:173.
When a marked URL is used while browsing, a warning “loading traced URL” in form of a yellow bubble below the address will be displayed, but the request will be executed.This must not appear every time loading a certain URL. If it does, please file a report in our bug tracker on GitHub.In the case of trk:173, an update of the spell checker from Google is loaded. From our view, this is no real problem, since no client data is submitted.
