Chanting Hall — trial build. Last updated: 2026-11-11. ← Back to the hall

1. The short version

No accounts. No sign-up. No tracking, no analytics, no advertising. Your practice records never leave your device. The live hall only ever sees an anonymous figure on a cushion, and the presence server keeps nothing after you leave.

2. Data stored on your device (localStorage)

The app stores the following in your browser's localStorage, on your device only:

• Practice records: today's counts (Heart Sutra rounds, mantra recitations, wooden-fish taps, minutes), your day streak and the last active day.
• Your chosen figure (avatar), your interface language and your hall preference.

This data is never uploaded by the app. You can erase it at any time by clearing the site's data in your browser. The Export button downloads a JSON copy of it to your own device; the Import button reads a file you choose — both happen entirely on your device.

3. The live presence service

When the live hall is connected, the presence service processes only anonymous presence information:

• the figure id you picked, a display name derived from that figure, your cushion number, and your language-hall preference;
• a random connection id generated for the session.

This information exists only in the server's memory, only while you are connected. The presence service writes nothing to disk, keeps no history, and does not log IP addresses. When you disconnect, your seat and your presence data are gone. The service's health check exposes only total connection counts.

As with any internet service, the network infrastructure that carries your connection (for example the web server or reverse proxy in front of the presence service) may keep standard technical logs; those are outside the presence service itself and are not used to identify practitioners.

4. Cookies and third parties

This trial build sets no cookies, runs no analytics and embeds no third-party trackers, fonts or scripts. The page and its assets are served as static files.

5. Payments and donations

This trial build takes no payments and accepts no donations, so no payment information of any kind is collected.

6. Changes and contact

If this policy changes, the updated version will be posted on this page with a new date. Questions about privacy: support@chantinghall.com
