Your Cupla data isn't gone — everything is stored against your account, not on your phone. You just need to install Cupla on your new phone and log back in with the same account you used before.
Logging back in
Download Cupla from the App Store or Google Play Store on your new phone.
Open Cupla. If on iOS, tap Already have an account?
Log in using the same method you used before — email, Apple, Google, Facebook, or Passkey.
Allow calendar and notification permissions when prompted so Cupla can sync correctly.
Once logged in, your partner connection, shared events, to-dos, and subscription access should appear automatically. It may take a minute or two for everything to sync.
If you accidentally created a new account
If Cupla looks empty after logging in, you may have ended up in a new account. Log out and log back in with your original details:
Tap More.
Tap Me.
Scroll to the bottom and tap Log Out.
Log back in using your original account details.
If you're not sure which account to use
Ask your partner to send you a login link from their Cupla app. See My partner got a new phone. How do they set up Cupla? for the steps — your partner can follow the same process to send you a link.
If you still can't access your data, message our support team from the Cupla app and we'll help you recover your account.
