// Submits build information to Realm when assembling the app
|
|
//
|
|
// To be clear: this does *not* run when your app is in production or on
|
|
// your end-user's devices; it will only run when you build your app from source.
|
|
//
|
|
// Why are we doing this? Because it helps us build a better product for you.
|
|
// None of the data personally identifies you, your employer or your app, but it
|
|
// *will* help us understand what Realm version you use, what host OS you use,
|
|
// etc. Having this info will help with prioritizing our time, adding new
|
|
// features and deprecating old features. Collecting an anonymized bundle &
|
|
// anonymized MAC is the only way for us to count actual usage of the other
|
|
// metrics accurately. If we don't have a way to deduplicate the info reported,
|
|
// it will be useless, as a single developer building their app on Windows ten
|
|
// times would report 10 times more than a single developer that only builds
|
|
// once from Mac OS X, making the data all but useless. No one likes sharing
|
|
// data unless it's necessary, we get it, and we've debated adding this for a
|
|
// long long time. Since Realm is a free product without an email signup, we
|
|
// feel this is a necessary step so we can collect relevant data to build a
|
|
// better product for you.
|
|
//
|
|
// Currently the following information is reported:
|
|
// - What version of Realm is being used
|
|
// - What OS you are running on
|
|
// - An anonymized MAC address and bundle ID to aggregate the other information on.
