Each “Contact” listed in your twinme app represents a unique and reciprocal relation between your device and your contact’s device. Whenever you accept an invitation from someone, twinme creates a new entry in your “Contacts” list, which indicates a new relation with that contact’s device. This means that you can have multiple relations with the same person, such as a work relation and a personal relation, each associated to a different name and image.
If you delete a contact entry, only the associated relation is removed, and it does not affect any other relation you may have with that same person.
