KUVRT

The emergency code

The emergency code is a second password. Typed on the lock screen, it deletes everything at once, as "Delete everything" does.

  1. Turn on the app lock with a password. Only then does "Emergency code" show on the "App lock" screen. Open App lock
  2. Tap "Emergency code". Type "Your password", then the code under "Emergency code" and "Emergency code again". Open Emergency code
  3. Tap "Set the emergency code".

The same screen has "Change the emergency code" and "Turn off the emergency code". Both ask for your password.

KUVRT refuses a code that is your password or one typo away from it, whatever the capitals. Pick one nothing like your password, so you never type it by mistake.

Typed on the lock screen, it asks nothing and cannot be stopped or undone. KUVRT then opens with an empty chat list under a new KUVRT with the same name, locked with the emergency code.

Your chats go from your contacts' devices too, as with "Delete everything". To them you are a stranger.

It works only while the lock screen shows. With "Lock after" at "1 hour", KUVRT may still be open when it matters, so choose a short time.

A new password turns the emergency code off, and so does "Turn off the app lock". Set it again after.

What this cannot do

  • An empty KUVRT can look like something was deleted. The code hides nothing about KUVRT having been used.
  • The new KUVRT is not quite like the old one: it asks you to save its recovery phrase, notifications are off, fingerprint or face is gone, and settings are back to their defaults.
  • Our server sees the deletion and the new KUVRT close together and could link them.
  • Anyone who copied the device's storage before has everything.
  • Screenshots, exports, what the keyboard learned, the notification history of the system and password managers are out of its reach.
  • People KUVRT could not reach keep their copy.

Using it while someone is watching, such as an official, can have consequences. Think about that before you rely on it.

KUVRT never asks for your recovery phrase, your password or your emergency code. Anyone who does is not us.
