What we use
OnSou only uses technical cookies and local storage, essential for the service to work. There are no advertising, third-party analytics or social media cookies, which is why no consent banner is needed.
List
fz_locale (cookie, 1 year): remembers the language you chose.
Authentication session (local storage, until you clear site data): keeps your anonymous account so you stay in your groups.
fz_name (local storage): remembers the name you used so you don't have to type it again.
fz_install_dismissed (local storage): remembers that you closed the install prompt.
Browser cache (service worker): stores the site's own files so it loads faster. It does not store positions or maps.
How to delete them
From your browser settings, by clearing site data for onsou.app. If you do, you will lose access to your groups until you rejoin with the code.
