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. (Apple sign-in is iPhone only: if you created your account with your Apple ID and your new phone is an Android, skip to If you’re not sure which account to use below.)
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.
If the Cupla app on this phone is showing your data, do not log out. Signing back in does not always return you to the same account, whichever phone you are on. An email address that already belongs to another Cupla account opens that account instead of yours, and anything you set up in the meantime, including a partner connection, is left behind. Message our support team from the app first and we will make sure your login is attached to your account.
Log out only from an app that is already empty:
On Android, try once. If logging back in still lands you in an empty app, stop there and message our support team rather than working through the other sign-in options: on Android an address we have not seen before can create a new blank account instead of opening your existing one.
Tap the menu icon (☰) in the top-left corner of the Home screen. If there is no ☰ on your Home screen, tap More in the bottom-right corner of the screen instead.
Tap Me.
Scroll to the bottom and tap Log Out.
Log back in using your original account details.
If your partner's app still shows the two of you as connected while yours does not, see We look connected on my partner's app, but not on mine.
If you're not sure which account to use
If your partner is on an iPhone, ask them 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. The option is iPhone to iPhone only: you and your partner both need to be on iPhones, and it appears only once your account has an email address on it. If either of you is on Android, it will not be there.
If you created your account with Sign in with Apple and your new phone is an Android, you sign in with an email code instead, sent to the exact address Apple gave Cupla when you signed up. To find that address, on any iPhone or iPad signed in to your Apple ID open Settings (on a Mac, System Settings), tap your name, then Sign in with Apple (on some versions it's inside Sign-In & Security), then Cupla. It's also at account.apple.com under Sign-In and Security. It will be either your own Apple ID email address or one ending in @privaterelay.appleid.com, which Apple forwards to your inbox. Then on your Android phone, open Cupla, tap I already have an account, tap Continue with Email, and enter that exact address. Any other address, even another one of yours, opens a new empty account.
If you still can't access your data, message our support team from the Cupla app and we'll help you recover your account.
