ProfCalendarAccount deletion is immediate and cannot be undone. Calendars you own, including shared calendars, disappear for their members too. Cancel a Play subscription separately.
- Export any ordinary calendars you want to keep before deleting. Warn members of shared calendars you own.
- Open Settings → Delete account on Android or in web Settings. Read the list of affected calendars and confirm only when ready.
- If you cannot access the app, use the account-deletion page to request help.
Your profile, memberships and owned calendars are removed. Content you contributed to calendars owned by others remains without your account attribution. There is no grace period. Export does not include cycle data. Deletion does not cancel Google Play billing.
If it still doesn't work
Check sync help or contact support. Tell us the app version and what you tried; never send passwords or private calendar contents.
