Are my data backed up?
We use Google Drive to backup your data. If you go to Setting > Backup and Restore and tap Backup, we will ask Google to save your data.
Once the backup is successful, you should see small toast confirmation "Yay! Backup created" and the date of your backup will be changed. If you see this Google has sent us a message that your data has been stored safely.
