Questions about user identification

[dyang]

Hi,

I understand TelemetryDeck's focus on privacy, and that it uses device identification as a base to identify users by default. I have three questions:

1. In case users use the same app on multiple devices, e.g. iPhone and iPad, does each device count as a unique user?
2. If a user deletes an app and later reinstalls it on the same device, will they be recognized as the same user or a new user?
3. If a user switches to a different device, e.g. by upgrading to a new phone, will they be recognized as a new user?

Thanks!
