In short: no account, no personal data collected. Your records stay only on your own device.
1. Information we do not collect
No account is required to use this app. We do not collect personal information such as your name, email address, or phone number.
The exception is the in-app "💬 Feedback" form. If you submit it, the message, feedback type, current page and language, and any optional email address you enter are sent to the operator through Formspree. We use them only to reply, investigate bugs, and improve the app.
2. Information stored on your device
Your settings, town name, discovery log, and weekly-clear records are stored in your browser's localStorage (the native app also mirrors them into the app's Preferences), on your device only.
This data is never sent to our servers.
Clearing your browser's site data, or deleting the app, removes these records.
3. Analytics
We currently use no analytics. Nothing is measured — not even visit counts.
In the future we may enable anonymous, cookie-free aggregate analytics (a privacy-preserving tool such as Plausible that does not identify individuals). If we do, we will update this page.
4. Third-party services
The charting library (Chart.js) is bundled with the app and is not loaded from an external CDN.
Feedback is sent to Formspree over encrypted HTTPS only after you press the submit button, and is processed under Formspree's privacy terms.
Sharing to X or LINE happens only when you explicitly tap a share button, and is handled under each service's own terms. If you don't tap it, no information is passed to those services.
5. Notifications (native app only)
In the native app (iOS / Android), notifications are limited to a once-a-week local notification. It stays within your device; no information leaves the device.
You can revoke notification permission at any time from your OS settings.
Deleting feedback you sent: to have a feedback submission (the message and any email address you gave) deleted, email info@veai.jp with the date you sent it and roughly what it said. We will delete it after checking. There is no account, so nothing else is held about you (records on your device are removed when you uninstall the app).
This app is free, non-commercial, and open source. We handle no data beyond what is described above.
Its purpose is not to gather anyone's information, but to let you experience "structures that can happen to any society".
