Day One Android supports two automatic backup methods—Day One Sync and text backups to Google Drive—and one manual backup method—JSON exports.
Backups are used to safeguard your data from loss. If you lose your phone or have a problematic update, backups are useful for restoring your data to your device(s).

Sync keeps data up-to-date across multiple devices and manages conflicts. Sync is primarily used if you use Day One on multiple devices (Android, iPhone, iPad, and/or Mac). Day One supports syncing data to as many devices as you'd like. Day One Sync stores your journal in the cloud and is easily re-downloaded when you log in on a new phone.
Sign into the server dashboard at https://dayone.app at anytime to verify data currently synced/backed up.
Note: The Day One app does not require an Internet connection to use it. All data is stored locally, so you have access to your information at any time. You can create and edit entries on multiple devices while offline and all the data will merge together properly once you are back online.
These are enabled in Day One > Settings > Advanced > Auto Backup to Google Drive. This must be enabled by you due to permissions needed to store data on Google Drive. These backups are a JSON export of the text of the entries only. Photos are not included in these automatic backups. To include photos, please use the manual export to JSON option (see below).
Day One Android supports exporting your journal data in the JSON file format—an open data format that can be imported back into Day One on any of your devices or saved in another location.
To manually export your journal into JSON, perform the following steps:
Go to Day One Android > Settings > Import/Export
Tap on Export Day One .zip file
Wait for the export to be created. This may take several minutes for larger journals
Tap on either Save to device to save the export to a local folder, or Share to send it to Google Drive, Dropbox, or another application of your choosing.
If you choose Save to device, the export will be located in a folder called Day One in the main directory of your device.
