If your suspicions are true, it means that the person hacked your Facebook account, your iCloud account, your Google, and then connected to happn or connected to the app via your phone number and/or from your phone.
In the first 3 cases, it is necessary to contact Facebook, Apple or Google directly and change your passwords. If you log in using your phone number, either someone has access to your phone or you have shared your credentials with a third party (which is against our T's and C's).
In any case, you can contact Customer Service as soon as possible, which will block your account while you secure your means of connection.
I think my account was hacked, what can I do?
