If you already have an account with Cupla, you simply need to sign in using the same credentials. However, if you accidentally ended up logged in to Cupla under a new account, you will need to follow these steps:
Tap the menu icon (☰). Depending on your app version, it will appear either in the top-left corner of the Home screen or in the bottom-right corner of the tab bar
Tap 'Me'
Scroll to the bottom and 'Log Out'
Log back in with your original credentials
If you have any trouble working out your original account credentials, and your partner is on an iPhone, please ask them to follow these steps. (Sending a login link is available on iPhone only, and only once your account has an email address on it. If your partner is on Android, or cannot see the option, message our support team from the app and we will restore your login for you.)
Tap the menu icon (☰). Depending on your app version, it will appear either in the top-left corner of the Home screen or in the bottom-right corner of the tab bar
Tap [Partners Name]
Tap 'Share login link with [Partners Name]' and send the link via your preferred messaging application
You will simply need to open the link from your mobile device with the Cupla App installed for the link to work.
If you would rather keep the new account than go back to your original one, your partner is the one who has to act: they disconnect from your old account and then connect to your new one. See We look connected on my partner's app, but not on mine.
