What is NO SUS?
NO SUS sends notes and files that open once. Write a note or add up to 10 files (50 MB combined) and get one link. It is encrypted in your browser, and the key stays in the part of the link after the #, which browsers do not send to the server. No account for the sender or the reader. For documents, Watermarked links put each viewer's typed email across the page and keep a view log (these links are not end-to-end encrypted). For text, Traceable copies give up to 100 readers a slightly reworded copy, so a pasted leak points to a reader's copy (a strong hint, not proof). The Android app (beta) opens PDFs with screenshots blocked. Free. Not open source.
