It is possible to have multiple accounts with Day One depending on the option chosen when signing into your account on each device. Here are the sign-in options: 

  • Apple ID
  • Day One account (email/password)

When using Apple ID to sign in, we use CloudKit technology provided by Apple and Day One receives a unique/anonymous token which we use to sign users into a Day One account based on the Apple ID being used in the device Settings. We never have access to the actual Apple ID credentials. 

A standard Day One account is one created by the user with an email and password. 

If you have two separate accounts, here is how to "merge" them. Be sure that your data is in the Day One app on at least one device. If your data is not present within Day One, please contact support for assistance first. These steps will not affect data in the app or a subscription status. 

  1. Before you begin, export your data as a JSON file. This can be re-imported if necessary. See here
  2. Sign out of Day One Sync in the app on all devices.

  • Open Day One on iOS and tap on the Settings icon.
  • Tap your account (Name, email) at the top.
  • Tap Sign Out.

macOS:

     3. Use these steps to delete the account with Apple ID. This does not affect data stored locally on the device. 

  • Go to dayone.me/user/login in a web browser, then click Authenticate with Apple ID below the Sign In button (see screen shot below).
  • Sign in using your Apple ID email address and password. (Note: This uses an official Apple-provided-and-secured web service.)
  • Click Account, then click Delete Account.
  • To confirm this choice, click the Authenticate with Apple ID then sign in again.
  • Click Delete My Day One Account.

     4. Go to back to dayone.me, and sign in using your original Day One account email address and password.
