I want to change my phone. How can I transfer the data?

On the Rankings screen, from the overflow menu, top right if the screen, select Export/Backup. Select which data you want to backup (URLs/time span), then scroll down and tap the Create Backup button. Save the backup file to some cloud storage service ,or email it to yourself. On the new phone, after installing SERmojo app, download the file on your phone and open it (or open directly from your email).
