I found a site that doesn’t collect much user data, but it seems to have been down for a while. Attempts to upload the file were unsuccessful.
Maybe you know a site with a good privacy policy where you can get direct links to the file?
A file retention period of at least three months is desirable.
I have said it before, but it is worth repeating, if you want to transfer a large file over the internet between two persons, Bit Torrent is still a good solution.
You obviously need to encrypt the data before sending it, but 7zip should sort that out for you, you then just create a torrent and send the torrent file over, and seed the torrent until completion.
As long as the file is securely encrypted and both sides terminate the torrent as soon as the intended recipient has the file, the risk of data leakage is minimal.
You don’t even need a tracker if the torrent client has the ability to do so.
Oh yeah, magnet links exists
