Flowvault · File Send

Send a file that self-destructs.

Drop a file (up to 10 MiB), pick how long it lives (up to 7 days) and how many times it can be downloaded, and share the link. The AES-256 key travels in the URL fragment (the part after #), so our servers never see it. After the final download the file is hard-deleted — not even Flowvault can bring it back. You’ll also get a secure delete link so you can destroy the upload yourself at any time. Learn more on the security page.

The encrypted file is hard-deleted from our storage the moment the last download is consumed — whichever comes first, downloads or expiry. Maximum retention is 7 days.

Also require a password to downloadAdds a second gate on top of the link’s secret key. Useful if the link might leak through email, chat, or a forwarded reply. Share the password through a different channel.

Encrypted client-side with AES-256-GCM. The key lives in the download URL’s #fragment— browsers never send fragments to servers, so even our database can’t decrypt the file.
