Hide Whatsapp profile picture from a certain user I want to hide the profile picture in WhatsApp and still be able to message this person. 

As far as I've understood, to message someone on WhatsApp, you need to store his/her number in the phonebook. Once you do this, you can't stop this person from seeing your picture, because WhatsApp does not have this options under the privacy settings. 

Changing the "Who can view my profile picture" to nobody is not an option. 

Also, if I delete the person from my phonebook, I will not be able to message his/her anymore. Same problem when using the app WhatsNot.

Is there a workaround or an app hide your profile pic from individual users?

Thank you for your help!
The only way would be creating a group with just you &amp; him, and then blocking him.. You'll not be able to message him directly, but only through that group (ofcourse he'll know you've blocked him).. 

Another way would be starting a conversation between you &amp; him and deleting his number (yes, it's mentioned in the question), but you'll still be able to chat with him (his number will be displayed instead of name) and make sure 'Who can see Profile Pic' is 'Contacts Only'..

Other than this, I don't think there's any other way..
