Secure file sharing

Secure file sharing, built to leave nothing behind

Most tools move a file from A to B and call it secure. Fliko goes further: the file is encrypted on your device, opened in a locked viewer, and deleted on a timer, so there is no lasting copy to leak.

"Secure" is an overused word in file sharing. Plenty of tools encrypt a file while it travels, then drop a permanent copy in the recipient's downloads and a link that works for days. That is not really secure. It just moves the risk somewhere you cannot see.

Fliko treats a secure share as something that should not survive once it has done its job.

What actually makes a file share secure

Three things have to be true, and most tools only do the first one.

  1. Protected in transit. The file should travel encrypted so nobody on the network can read it. Table stakes.
  2. Not readable by the service. The company moving your file should not be able to open it. With Fliko, standard files are encrypted on your own device with AES-256-GCM before they are uploaded, so our servers hold only the scrambled version.
  3. Gone afterwards. A secure share should not become an insecure copy the moment it is opened. This is the part almost everyone skips.

How Fliko secures a share

You pick a file, choose how it can be opened, and set a self-destruct timer. From there:

  • View-only mode opens the file in a locked viewer inside the Fliko app, with no download. On Android, screenshots and screen recording are blocked. On iPhone, Apple does not let any app block screenshots, so instead the content blanks out in a capture and you get a real-time alert. We will not pretend iOS can do more than that.
  • The timer starts when the file is first opened, not when you send it, so nothing expires before the right person sees it.
  • When the timer ends, the file is deleted from our storage and backups, and the access link dies with it. There is no recovery.

If you allow downloading instead, the recipient can save a copy, and we are honest that a downloaded file is theirs to keep. For anything you do not want copied, use view-only.

Secure sharing vs. ordinary file sharing

Ordinary sharing optimises for convenience: big files, long-lived links, easy saving. That is fine for a holiday video. It is the wrong default for an ID, a contract, or a medical report, because every convenience is also a copy waiting to leak.

Fliko optimises for the opposite. The share is temporary by design, view-only when it needs to be, and gone when its time is up.

Try it in your browser

You can send a secure share from fliko.in right now, no install needed, up to 250 MB and 10 files per share with a 1 to 10 minute timer. For larger files and longer timers, the iOS and Android app gives you more room.
