How to set up end-to-end encryption

This article describes the steps to set up end-to-end encryption for Day One Sync.

End-to-end encryption utilizes a private key to encrypt all your journal entries before they reach Day One servers. Since the encryption key is held only by you, you can be sure your journals are protected with maximum security.

If you’re on an Apple device, the encryption key is stored securely using iCloud through your Apple ID. If you’re on Android you can back it up to Google Drive or iCloud in Settings> Sync> Encryption Key. You can also save or print your key to be stored securely in your possession. Please keep this somewhere safe. We don’t have a back up copy for you.

Please note that journals cannot be switched back from end-to-end encryption to standard.


Open Settings > Journals. Any journal with a shield icon is end-to-end encrypted. Tap any journal and then tap Advanced for the encryption setting. 

As of version 4.2, encryption is enabled by default and a private key is generated automatically. It is stored securely in iCloud. You can also access it at any time if you are logged in by selecting “Show Encryption Key” in the Sync setting. 


If enabling encryption manually on previously synced journals the standard encrypted journal is deleted from the server and new encrypted entries are uploaded from the device that turned it on. Please allow the sync process to complete before making changes on this or other devices.


Enabling end-to-end encryption on the Mac is very similar. Open Preferences > Journals.  If needed, generate an encryption key first.  Then click the “i” icon next to the journal you wish to encrypt and change the encryption option.

If you have already enabled encryption from iOS, you will be prompted on Day One Mac to input your encryption key. You can enter the key manually, use the on-screen scanner to scan the PDF you have saved, or use the front-facing camera on your Mac to scan the key from your iOS device.


 Enabling end-to-end encryption on Android is very similar to iOS.

Settings > Journals > Tap a journal > End-to-End Encryption > Tap Confirm
