![]() Photos are saved in Local Storage/Device Storage/Conversations/Media. You can turn off Storage access for the app, thus preventing any photos or files from being able to be saved to the device, but that also prevents them from being downloaded and viewed in the app as well, essentially making Conversations a text only messenger. And if you have any backup or cloud syncing setup for your photos then these photos from Conversations wil also show up in your online storage. You will need to scan the QR code for each of your contact's devices on all of your devices.Īnother aspect of security is that photos are automatically saved to your phone's photo gallery where they are saved unencrypted. Also if you have more than one device verifying a key on one device does not make that key verified on other devices. If a contact has multiple devices then a key for each device will need to be individually verified. Once verified any messages from the contact will show a shield icon. The verifying of a contact's OMEMO keys is done through the exchange of QR codes that are scanned. In many ways it is very similar to PGP which only added encryption to the message contents of emails. It is just the nature of this system that confidentiality is only available for message contents. OMEMO adds encryption to the message contents, but the underlying system of XMPP remains unencrypted. When XMPP was first developed there was no encryption implemented in the design. All your contacts are stored unencrypted.Some goes for the files which are uploaded encrypted. Other meta data with the message is not encrypted. Even if the messages are OMEMO encrypted it is only the message contents that are encrypted. Archiving of messages on the server is a concern.Regarding the above information, even with OMEMO enabled the following is unencrypted on the server: A correlation between your account and your payment information for longer than it is necessary to fulfil our return policy.Or more general the times when you use our services. Your IP address or any information that could be inferred by that address like your location.Other private data your XMPP client might upload like a list of conference bookmarks. ![]()
