Two-Way Contact Sync

We're excited to introduce Two-Way Contact Sync, a new feature that keeps your Dex contacts updated across all your devices automatically. Any changes you make in Dex or on your device stay in sync, so your contact list is always up to date.

How it works?

• When you first connect your device to the Dex Sync Server, it downloads all your existing contacts.
• Any changes you make on your devices are automatically synced to your Dex account.
• Any changes made on Dex are automatically synced to your device.
• This happens in real-time or when your device checks for updates.

What the two directions are

The two directions are Dex and your device's own address book. Dex runs a CardDAV server, your device connects to it as an account, and contacts move both ways between those two places.

Google Contacts and iCloud are not part of that loop. Dex reads from Google when you connect a Google account, and it never writes back, so an edit you make in Dex does not reach Google Contacts and does not reach iCloud.

What gets synced?

• New contacts you create
• Deleted contacts will be removed from all your devices.
• Merged contacts: when you merge two contacts in Dex, the duplicate is deleted, so it is removed from all your devices too.
• Archived contacts will be removed from all your devices but can be restored anytime from the Archive page, under the drop-down menu at the top-right corner.

The following contact information will be synced across all your devices:

• Name
• Description
• Emails & Phone Numbers
• Company & Job Title
• Addresses
• Social profiles
• Profile images
• Birthday
• Website URL

Limitations

Dex Contacts does not sync certain types of contact information. The following are the currently known limitations:

• Dex only supports syncing a single website URL per contact; if multiple URLs are present, only the first one will be synced.
• Limited support for social media profile links.
• Special dates, such as anniversaries, are not supported and will not be synced to Dex.
• Custom fields will not be synced to Dex.

Get Started

Two-way contact sync is available to everyone. There is no waitlist and nothing to request.

Conflict Resolution

To ensure your contact data stays consistent across devices, an automatic conflict resolution process is used. Here's how it works:

• If the same contact is edited on multiple devices, the most recent update will take precedence and overwrite older changes.
• This is seamlessly handled in the background to prevent duplicate contacts and maintain data accuracy across all your devices.

Reliability

Dex is built to keep your contacts safe and in sync — no matter what.

• Syncing is reliable and secure, so your updates are always protected.
• If your device goes offline, any changes you make will automatically sync once you're back online.
• Your contacts are securely backed up on Dex's servers, so you never lose important information.

Privacy & Security

Your contact information is safe with Dex.

• All syncing is encrypted to keep your data private.
• Only you have access to your contacts—no one else can see them.
• Your information stays protected throughout the entire sync process.
