If your device has SD card and your android OS is lower than 5.0, your notes will be backed up to the SD card. If your device doesn’t have SD card or if your android OS is 5.0 (or higher version), your notes will be backed up to the internal storage of your device.
The backup location for internal storage is ‘/main storage/data/colornote/backup’. If you use file manager app on your mobile device, the ColorNote backup file will appear in ‘/main storage/data/colornote/backup’. However, if you try to see ColorNote backup file on the pc by connecting the mobile to your PC, backup file will appear in ‘/data/colornote/backup’
* However, if you had not allowed ColorNote to access your photos, media, and files on your device after installing ColorNote, your notes would not have been backed up to your device.
