Privacy Policy — HOSHINZO
HOSHINZO is built on a simple principle: your data belongs to you and has no reason to leave your device.
No data collected
HOSHINZO collects no personal data. The app works entirely offline. It requires no account, no sign-up, and no internet connection to function.
No data transmitted
No information is sent to our servers or to third parties — in fact, we have no server. Your preferences, favorites, and session history are stored only and locally on your device. They are deleted if you uninstall the app.
No tracking, no ads
HOSHINZO contains no analytics tools, no advertising trackers, and displays no ads.
External links
The app contains links to scientific publications (DOI references). Opening them takes you out of the app and into your browser. These external sites have their own privacy policies, which we do not control.
Changes
Any update to this policy will be posted on this page with a new date.
