Please remember the default behavior of YunoHost when installing a new app is: everyone has access to the app.
This may be an issue for Kresus as it is a personnal tool. Please remember to edit access rights in the YunoHost web administration panel or using command line interface.

Are you facing an issue, want to improve this app or say thank you?
Please open a new issue in this project: https://github.com/YunoHost-Apps/kresus_ynh
