Some things should not sit in a chat history for years: a Wi-Fi password, a
bank detail for one payment, an address, a private message. With KryVault you
write the note once, send a link, and the link stops working when you decide.
How to send a private note
Create a free vault. No email, no phone number — a random key is your account.
Press New note, write your message and save it. It is encrypted in your browser before it is uploaded.
Press Share next to the note and choose how long the link should work: 1 day, 7 days or 30 days.
Send the link. The other person opens it and presses Show note. They can read it, copy it, and that is all.
What makes it private
The key is inside the link, after the #. Browsers never send that part to a server, so the key goes from you to the other person and never to us.
We store only scrambled text. We cannot read the note, its title, or anything else in your vault.
You can take it back. Press Stop sharing, or delete the note, and the link dies straight away. If you set 1 day, it also stops by itself tomorrow.
You can see if it was opened. Each link shows a download count, with nothing about who opened it.
Good uses
Passwords and Wi-Fi details for a guest or a new colleague.
One-time bank or UPI details you would rather not leave in WhatsApp.
A home address or a phone number for someone you have just met online.
A private message for one person — a confession, a warning, something personal.
Recovery codes you need to move from one device to another.
What it does not do
It is not “burn after reading”. The link keeps working until it expires or you stop it, so the person can open it more than once. Choose 1 day for short-lived secrets, and stop the link once they have read it.
Anyone with the link can read the note. Send it only to the person it is meant for.
Once someone has read a note, they can copy it. No tool can stop a screenshot.
Common questions
Can KryVault read my note?
No. The note is encrypted in your browser before it is uploaded. The key is in the part of the link after #, which never reaches our server.
Does the note delete itself after reading?
Not automatically. The link works until it expires (1, 7 or 30 days) or until you press Stop sharing or delete the note — whichever comes first.
Does the reader need an account?
No. They only need the link and a web browser.
Is sending notes free?
Yes. Notes and share links are included in the free 100 MB vault. There is no sign-up.
