Currently WhatsApp claims it uses end to end encryption.
However the app provisions users to switch on backups to Google Drive and other providers. So if I am in a group chat with a set of users and send out sensitive/personal information, I assume I can delete my chat at any time and make a request to WhatsApp to delete any information on me when I delete my account.
However if other users are backing up their chats to say Google Drive etc how can I ensure my data is deleted from everywhere?
I understand anyone can just screenshot or copy this data from their device and paste it somewhere. But the app itself provisions for these backups so does WhatsApp have a duty under Right to Erasure / GDPR to ensure they can also be deleted if a request is made for an individual?
