Yes Fnoord, this is one potential use case but not the primary one.
Our focus is on giving people an EASY and SECURE way to send their file to each other.
Most other services out there are easy to use but not secure or private, or very secure, but you need to be a semi developer to use them. If anyone shares their file publicly, it will be their responsibility.
All the files will be split and encrypted, then uploaded to a random hub on your provider of choice. Of course, we provide a free provider. No matter what provider, all files will be encrypted before leaving your machine.
About delete, as the name suggests, we don't have control on your file, we will encrypt it, give you the key, and then send it, like a very secure post.
