Most ways of sending a file leave a trail: WhatsApp ties it to your phone
number, email ties it to your inbox, and Google Drive ties it to your Google
account. KryVault lets you send a file with a link that is not tied to any
name, number or email — yours or theirs.
How it works, in four steps
Create a free vault. No sign-up — your browser makes a random 28-character key, and that key is your whole account. Save it somewhere safe.
Upload the file. It is encrypted inside your browser before it leaves your device, so our server only ever holds scrambled data.
Press Share and pick how long the link should work — 1 day, 7 days or 30 days.
Send the link by any app you like. The person opens it in a browser and downloads the file. They do not need an account, an app or your vault key.
Why the link is private
A KryVault share link looks like this:
kryvault.com/s#Abc…xyz.Q7k…p2E. Everything after the
# is the key that unlocks that one file. Browsers never send the
part after # to any server — so the key goes from your browser,
through whatever app you send it with, straight to the other person’s browser.
We never receive it.
We cannot open the file. We store only scrambled data, plus a scrambled copy of the file name that only the link can unlock.
The link opens one file only. It does not reveal your vault key, your other files, or your folder names.
You stay in control. Press Stop sharing at any time, or delete the file, and the link stops working at once. Every link also expires by itself.
You can see whether it was used. Each link shows how many times it has been downloaded — nothing about who downloaded it.
Good reasons to send a file this way
Sending an ID copy, a medical report or a property paper to one person, without it sitting in a chat history forever.
Passing documents to a lawyer, a journalist or a support group without linking them to your phone number.
Sharing a file with someone you do not want to give your email or WhatsApp number to — a buyer, a landlord, a stranger online.
Sending something from a shared or office computer without signing in to anything.

Being honest about the limits
Anyone who has the link can open the file. Treat the link like the file itself. If you paste it in a group, everyone in the group can download it.
The app you send it with still knows who you sent a message to. KryVault keeps the file private; it cannot hide the fact that you messaged someone. For the most privacy, send the link through an app that does not need your phone number.
Size. The free vault holds 100 MB in total. Paid plans hold 5 GB or 20 GB.
Downloads count towards your vault’s monthly download limit (three times your storage each month), which stops links being used to spread big files to thousands of people.
Like any website, our hosting provider sees IP addresses when people connect. We use them only to deliver the page and stop abuse. For more, see privacy.
Common questions
Does the person receiving the file need an account?
No. They open the link in any modern browser and press Download. They do not need an account, an app, or your vault key.
Can KryVault see the files I send?
No. The file is encrypted in your browser before upload, and the key that unlocks it is in the part of the link after #, which browsers never send to any server.
How long does a share link last?
You choose 1 day, 7 days or 30 days. You can stop a link earlier at any time, and deleting the file stops every link to it.
Is it free?
Yes. The free vault holds 100 MB for 90 days, and sharing is included. There is no sign-up and no card.
