* The option to show caller info notifications is enabled by default, so the app will ask for phone-related permissions.
* At first start, the app will suggest to download main database which is required for most of the functions. Simply confirm the download.
* Check the "Auto-update database" checkbox in the menu (recommended) to automatically receive daily DB updates (these are incremental/delta updates, so they consume very little traffic).
* Check the "Block unwanted calls" checkbox to block calls with negative rating automatically.
