Accidental app uninstall

1 week ago I accidentally uninstalled an app containing important passphrases.

Is it possible to restore the state of my system to the situation prior to that uninstallation?

No, unfortunately that is not possible

Peut être si vous avez utiliser votre espace de sauvegarde dans iode os

Is it possible to write in english, please.
It is an international thread!
Thank you
