Contacts

Set up CardDAV

Sync your Locari contacts to iPhone, iPad, Android, macOS, Outlook, or Thunderbird — one-time setup, automatic updates from then on.

With CardDAV sync, your Locari contacts are available on all your devices: iPhone, iPad, Android (DAVx5), macOS, Windows Outlook (plugin), and Thunderbird. After the one-time setup, changes sync automatically — no manual export needed.

What Locari provides: A CardDAV server your devices can read contacts from. What you set up: One device password per device and the connection in the respective app. No third-party account required.

Common Tasks

  • Create a device password
  • Set up iPhone or iPad
  • Set up Android with DAVx5
  • Set up macOS Contacts
  • Set up Windows Outlook
  • Delete a device password

How to

Create a device password

  1. Open Contacts, click Mobile Sync in the top right — you will be taken to User settings → Address Book.
  2. Click New Device, enter a name (e.g. "Erik's iPhone" or "Office MacBook").
  3. Click Generate Password — the password is shown once, so copy it immediately.
  4. Use the password during device setup (steps below).

The device password is shown only once. If you did not save it, delete the password and create a new one.

The step-by-step guides (one accordion per device type) only appear on the Address Book page once you have created at least one device password. You can create up to 10 device passwords per user.

iOS / iPadOS

Automatic via QR code (recommended):

  1. Create a device password (see above) — the page then shows a QR code.
  2. Scan the QR code with the iPhone/iPad camera app.
  3. Tap "Profile downloaded" in Settings.
  4. Install the profile and enter the device password.

Manual setup:

  1. Settings → Contacts → Accounts → Add account → Other → CardDAV account.
  2. Enter the server URL (displayed and copyable on the Address Book page).
  3. Username: your Locari email address. Password: device password.
  4. Tap Next → Save.

Android (DAVx5)

  1. Install DAVx5 from the Google Play Store.
  2. Open DAVx5 → + → Login with URL.
  3. Enter the server URL (copy from the Address Book page), your email, and device password.
  4. Tap Create account — DAVx5 syncs your contacts.

Example: Portfolio manager Daniela sets up DAVx5 on her Android tablet and has all 45 contacts from her portfolio automatically available in the native contacts app.

macOS

  1. System Settings → Internet Accounts → Add Account → Other Account → CardDAV Account.
  2. Account type: Advanced. Copy and paste the server URL from the Address Book page.
  3. Username: your Locari email. Password: device password.
  4. Click Sign in — contacts appear in the macOS Contacts app.

Windows Outlook (plugin)

Outlook does not support CardDAV natively. The free open-source plugin CalDav Synchronizer is required.

  1. Download and install CalDav Synchronizer from caldavsynchronizer.org.
  2. Restart Outlook → CalDav Synchronizer → Synchronization Profiles.
  3. Click Add → create a CardDAV profile, enter server URL, email, and device password.
  4. Click OK — the plugin syncs on the next Outlook start.

Thunderbird (TbSync)

  1. In Thunderbird: Add-ons → install TbSync and Provider for CalDAV & CardDAV.
  2. TbSync → Add account → CalDAV & CardDAV.
  3. Enter server URL, your Locari email, and device password → click Create account.

Other clients

For any other CardDAV-capable app, enter the details manually. The server URL and username are copyable in the Other Clients accordion:

  • Server URL: shown and copyable on the Address Book page
  • Username: your Locari email address
  • Password: the device password you created

Connections and Fields

Address Book page — device passwords

Accessible via Contacts → Mobile Sync or directly at User settings → Address Book. The device-password table shows:

  • Device Name — freely chosen for identification (e.g. "Erik's iPhone")
  • Active — the connection is usable
  • Last Used — time since the most recent sync (or "Never used")
  • Actions — delete the password via the three-dot menu

Server URL and credentials (for manual setup)

  • Server URL: https://app.locari.ai/api/carddav/principals/{your-user-id}/ (copyable with one click on the Address Book page)
  • Username: your Locari email address
  • Password: the device password created above (not your Locari login password)

Delete a device password

Delete the password from the device first, before removing it in Locari. If you only remove it in Locari, the device will keep trying to connect. After 5 failed attempts, your IP address will be blocked for 15 minutes.

Order of operations:

  1. Device: remove the account or profile in the respective app.
  2. Locari: User settings → Address Book → delete the password via the three-dot menu.

Device-specific removal steps:

  • iOS: Settings → General → VPN & Device Management → "LOCARI Contacts" → Remove profile.
  • macOS: System Settings → Internet Accounts → "LOCARI" → Remove account.
  • Android (DAVx5): Open DAVx5 → select account → menu → Delete account.
  • Outlook: CalDav Synchronizer → Synchronization Profiles → select profile → Delete.
  • Thunderbird: TbSync → select account → Remove account.

Good to Know

  • Device passwords are personal: each user manages only their own passwords — up to 10 per user.
  • Full list: the complete contact list of your workspace is synced per device password.
  • One password per device is recommended so you can disconnect individual devices precisely.
  • You edit the contact list itself under Contacts.
