Private by design

Your journal is encrypted on your phone. Ovanest has no account, no server for your health data, no ads, no analytics and no tracking. Backups are encrypted on your phone with a passphrase only you know, so nobody else can read them, including us. Reminders are discreet, so your lock screen never mentions your cycle.
