If you get logged out of your account, you will need to get back to the login screen. Here is what you need to do:
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 to return you to the login screen
Tap 'Already have an account?'
Enter the email address you used to create your original account and follow the prompts
If Cupla does not recognize the email address, it could be that you originally created your Cupla account using your Apple ID. Cupla is unable to confirm this as Apple obfuscates the address. On iPhone, choose the Apple option on the login screen and sign in with your Apple ID — it is worth trying even if you are not sure you used it. On Android there is no Apple sign-in option, so follow the steps below or message our support team from the app and we will restore your login for you.
If you still cannot access your account, your partner's app shows the address your account signs in with: ask them to tap the menu icon (☰), tap your name, and read the address on your profile screen. Sign in with that address, or with the Google or Apple account that uses it. If you and your partner are both on iPhones, they can also send you a login link. (The login link is iPhone to iPhone only: it appears on their iPhone only when you were last on an iPhone too, and only once your account has an email address on it. If either of you is on Android, it will not be there.)
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.
