Point their phone at this. Two seconds, no typing, nothing to mis-hear.

Your own devices only. Type here, it turns up on your phone. Nobody else can see it — there is nothing to deliver.
What one other person sees. It updates for them each time you save. They can only read — nothing comes back.
Drag this to your bookmarks bar (desktop), or add it as a bookmark and paste the code as its URL (iOS Safari). Tap it on any page to save it to Quick Stash.
Runs one real send end to end — encrypt in chunks, upload resumably to your Drive, fetch it back the way a recipient's browser would, decrypt it and compare every byte, then register and resolve a short code. About 9 MB, and it deletes everything it makes.
Permanently delete everything KTRD stores in your Google Drive — every saved tab group, note, share link, sent file, and your mailbox. Your Google account stays connected; only your data is erased. This can’t be undone.
