Is gemz as safe as threema? And what´s the diference between normal chat and secret chat? Does the normal chat save any informations (and secret not?) or is the possibility of self deleting messages the only difference?
edit: And/or what does "leave no trace on our servers" mean?
While all messages are always securely encrypted, messages in Secret Chats use client-client encryption, while regular chats use client-server/server-client encryption and are stored securely encrypted in the cloud. This enables your regular messages to be both secure and immediately accessible from any of your devices, you can also easily find them using server search — which is very useful at times.
Secret chats are meant for people who want more secrecy than the average fella. All messages in secret chats use end-to-end encryption. This means only you and the recipient can read those messages — nobody else can decipher them. Messages cannot be forwarded from secret chats. And when you delete messages on your side of the conversation, the app on the other side of the secret chat will be ordered to delete them as well.
You can order your messages, photos, videos and files to self-destruct in a set amount of time after they have been read or opened by the recipient. The message will then disappear from both your and your friend's devices.
All secret chats are device-specific. This means, you can only access messages in a secret chat from their device of origin.
