- If your device goes offline, any changes you make will automatically sync once you’re back online.

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.

FAQ
Is sync supported on all devices and operating systems?
Is sync supported on all devices and operating systems?
Two-way contact sync works with most major platforms that support CardDAV, including iOS, Android, macOS, and Windows. Some third-party apps may have limited support. For the best experience, follow the platform-specific setup instructions provided in the Dex app.
Why don’t I see my contacts?
Why don’t I see my contacts?
After setting up sync, your device may take a few minutes to download your Dex contacts — especially if you have a large number of them. This is normal. Once the sync is complete, your contacts will appear in your device’s address book. If they don’t show up after a while, double-check that the account is enabled in your contact settings and that you followed all setup steps correctly.
Sync seems delayed – is that normal?
Sync seems delayed – is that normal?
Yes, that’s expected. Most devices sync contacts periodically, not in real time. So, after you make changes in Dex or on your device, it may take a little while for the updates to appear. The timing depends on your device’s sync schedule and your network connection. A stable internet connection helps ensure sync happens smoothly, but some delay is normal. If you don’t see updates after a reasonable time, try refreshing your contacts.
Do I need to keep the Dex app open for sync to work?
Do I need to keep the Dex app open for sync to work?
No — once sync is set up, your device handles syncing in the background using the CardDAV protocol. You don’t need to have the Dex app open for it to work.
How do I turn off contact sync?
How do I turn off contact sync?
