Privacy Policy

Effective and last updated: July 29, 2026

1. Basic policy

Yohaku requires no account and uses no advertising or behavioural analytics SDK.

Space periods, display preferences and notification settings are stored on your device. The operator cannot view these records.

If enabled, local notifications are scheduled on your device. Your records are not sent to an external server for notifications.

Only when you use the support form do we process the information you enter and your reply-to email address to answer your enquiry.

Changes to this policy will be published on this site with an updated revision date.
