Inboxes
Inboxes are a special kind of communication tool used for one way communication with external users.
An authorized PrivMX user can create an Inbox, configure it's snippet and place it in a desired place (like webpage or an app). Anonymous, unregistered users can send data to the Inbox. This procedure uses Inbox Public Key, which allows to write data to an Inbox. One time access assures that the writer has no possibility of reading the data once it's sent.
Inboxes can be organized as source-specific containers, where anonymous users from each source can securely submit encrypted data (messages/forms/files). All the active users are notified right away when new data arrives. The data can be plain text or binary.
All the data is stored in the Bridge and can be freely accessed by authorized users.
