Is your calendar not appearing in XNeuronal?

XNeuronal reads the calendars your Android phone knows about, and adds the appointments you dictate to them. If your calendar is missing from the list, it's almost always a setting in its app. Here's which one.

How XNeuronal reads your calendars

On Android, each calendar app that syncs an account (Google, Microsoft, Samsung, etc.) deposits its appointments into the phone's calendar. XNeuronal reads this calendar, never the provider's server: no password to give, no connection to authorize.

In Settings > Phone Calendar, you check the calendars to read one by one. Their appointments become cards: the morning briefing and "what do I have this week" know about them. You also choose which calendars XNeuronal adds the appointments you dictate to.

Nothing is read until you check something. Unchecking stops reading, already imported cards remain, and Settings > Memory > Clear removes them calendar by calendar.

The setting, app by app

Outlook, Microsoft 365, Exchange

Why isn't my Outlook calendar appearing?

  1. Open the Outlook app.
  2. Go to your account, then Calendar.
  3. Enable "Sync calendars".
  4. Go back to XNeuronal and tap "Refresh list".

An IMAP or POP account doesn't have a calendar: Outlook can't sync anything for it. A Microsoft 365 or Exchange business account has the same button.

Proton Calendar

How do I connect Proton Calendar?

  1. Install "Sync Provider for Proton" from the Play Store, the official Proton app.
  2. Connect your Proton account within it and enable the calendars to sync.
  3. Go back to XNeuronal and tap "Refresh list".

Proton doesn't offer CalDAV: this app is the only gateway to the phone's calendar.

iCloud, Nextcloud, Fastmail, Infomaniak, Zimbra, Yahoo

How do I connect iCloud, Nextcloud, or another CalDAV calendar?

  1. Install DAVx⁵ (paid on the Play Store, free on F-Droid).
  2. Add your CalDAV account with your provider's address.
  3. For iCloud, first create an app-specific password on appleid.apple.com: your usual password will be rejected.
  4. Go back to XNeuronal and tap "Refresh list."

DAVx⁵ syncs both ways: an appointment dictated to XNeuronal goes back to iCloud or Nextcloud.

Samsung Calendar, Mi Calendar, DigiCal, Business Calendar

I'm looking for "Samsung Calendar" in the list and can't find it

  1. These apps don't have their own calendars; they display the phone's calendars.
  2. In XNeuronal, look for the calendar under the account name (your Gmail address, your Samsung account), not under the app name.
  3. The "My Calendar" calendar on a Samsung without an account appears under "Phone."

POP or IMAP email account (OVH, Free…)

How do I add a POP or IMAP account, for example with OVH?

  1. A POP or IMAP email account only carries messages: it doesn't have a calendar, so there's nothing to sync.
  2. Check what calendar your provider offers alongside the mailbox.
  3. Exchange (OVH Exchange, Microsoft 365, corporate server): install the Outlook app, add the account, enable "Sync calendars."
  4. CalDAV (OVH Email Pro and Zimbra, Infomaniak, Fastmail, Nextcloud): install DAVx⁵ and add the account using the CalDAV address provided by your provider.
  5. A simple email account (OVH MX Plan, Free) doesn't have a calendar: keep your Google Calendar or your phone's calendar.

What XNeuronal keeps for you

The name of your calendars (often an email address) never appears in a shared card or on a public page. Imported appointments are cards like any others, with the same privacy rules.
