To edit your profile info, tap the profile icon, then tap "My profile".
Here, you can update your photos, edit your bio, add your work or school info.
You have to go to your profile settings, tap "my profile", then click on "my photos" and there you will be able to delete or add photos.
You are either visible to others looking for people like you or invisible for everyone. If you chose so, you can hide your profile by visiting Fruitz > Settings > Hide my profile.
Your profile is hidden on the app, which means people can no longer see your profile and you can no longer see and like new profiles. You will only have access to your matches received before the switch to hidden mode.
