Delete Your Banri Account and Data

This page explains how to delete your account and data in Banri (伴日; developer: YT Vibe Studio, led by Yu-Tung (Jack) Chang). You can do it yourself in the Android app or on the web version, without contacting us and without having to install the app first.

Steps to delete

1. Open the Banri app, or go to dodo.emtpjack.workers.dev in a browser, and sign in with the Google account you want to delete.
2. Tap “Settings” in the top-right corner → “Account & sync” → “Remove account…”.
3. Review what will be deleted; you can tap “Export a backup first” to keep a copy.
4. Tap “Permanently remove account”. Google will ask you to confirm your identity once more, and deletion happens immediately after that.

Data that will be deleted

• Your account (the account created in this App through Google sign-in)
• Your personal calendar and all events, to-dos, items you're waiting on, and things to prepare in it
• Shared calendars you created and everything in them (other members will no longer see them either)
• Personalization settings: your assistant's name, what it calls you, speaking style, life areas, daily routine, iCal URLs, and Google Calendar connection
• AI answer reports and feedback you submitted
• Reminder schedules and push subscriptions for all devices
• Local data on the device used to delete the account

Data that will be kept

• Shared calendars created by others that you were invited to: you will leave them automatically, but items you added to them belong to that shared calendar and will remain for the other members (still showing your name at the time). If you want them removed, delete those items yourself before deleting your account.
• Local data not yet cleared on other devices you have signed in on: you can delete it on that device in Settings → Data → Clear local data.

Cloud data is deleted from the database immediately after you confirm, and cannot be recovered.

Only want to delete some data?

• A single event or to-do: tap Delete on its edit screen.
• Shared calendars: in Settings → Shared calendars → Manage, you can delete calendars you created or leave calendars created by others.
• Google Calendar connection: Settings → Google Calendar → Disconnect.
• Stop using AI: in Settings → My assistant, turn off “Use AI to organize and answer questions”.
