If your partner has a new phone, they simply need to install Cupla and log in using their original account. They do not need to create a new account or reconnect with you again.
Here is what your partner should do:
Download Cupla from the App Store or Google Play Store on their new phone.
Open Cupla, if on iOS tap Already have an account?
Log in using the same method they used before, such as email, Apple, Google, Facebook, or Passkey. (Apple sign-in is iPhone only: if their account was created with an Apple ID and their new phone is an Android, skip to If your partner is not sure which account to use below.)
Allow calendar and notification permissions when prompted so Cupla can sync correctly.
If they sign in by email, the 6-digit code is sent to whichever address they type, so it has to be the address on their own Cupla account, not yours. To check which one that is, tap the menu icon (☰), tap their name, and their email address is shown on their profile.
Once they are logged in to the correct account, your partner connection, shared events, to-dos, and subscription access should appear automatically. It may take a minute or two for everything to sync.
What if my partner accidentally created a new account?
If your partner ends up in a new, empty Cupla account, ask them to log out and return to the login screen:
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 their original account details.
If your partner is not sure which account to use
If you are on an iPhone, you can send them a login link from your Cupla app. (The option is iPhone to iPhone only: you need to be on an iPhone and so does your partner, and it appears only once their account has an email address on it. If either of you is on Android, it will not be there. Read their address off their profile instead, using the steps above, and have them sign in with that.)
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 your partner's name or profile circle.
Tap Share login link with [Partner's name].
Send the link using your preferred messaging app.
Your partner should open the link on their new phone with the Cupla app installed. This will help them access the correct account.
If their account was created with Sign in with Apple and their new phone is an Android, they sign in with an email code instead, sent to the exact address Apple gave Cupla when they signed up. If you can't see that address on their profile, they can find it on any iPhone or iPad signed in to their Apple ID: open Settings (on a Mac, System Settings), tap their 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 their own Apple ID email address or one ending in @privaterelay.appleid.com, which Apple forwards to their inbox. On their Android phone, they open Cupla, tap I already have an account, tap Continue with Email, and enter that exact address. Any other address, even another one of theirs, opens a new empty account.
If they still cannot access the correct account, please message our support team from the Cupla app.
