Thread protects users' data by saving it to local iPad storage, and then to Thread’s server using a data sync process. This two-step process safeguards data by providing an immediate backup to the cloud every time data changes. Due to this process, the Thread application can be utilized offline without an internet connection. If a user is temporarily working offline, data syncing will resume immediately with a reliable internet connection.

Please note, to protect data that has not been synced, do not uninstall the Thread application. These actions will remove data from the iPad before a sync can occur. It is strongly recommended to perform your own data backups in addition to those Thread by CentralReach provides.

Offline Work and Unreliable Internet

Virtually any change to local data triggers a sync. When there is an active connection to the server, the data will sync immediately, or as fast as the internet upload speed allows. If the Thread application is unable to sync new data to our server, it will retry every ten seconds until successful.

After ten minutes without a successful data sync, an alert will display across the top of the screen. Return to an active connection as soon as possible and data will sync automatically.

How to Recognize and Address Problems with Data Sync

If the data sync alert appears unexpectedly, there may be a problem with your iPad, the internet connection, or our server. Here are some considerations:

Caution - Protect your data if a sync has not yet occurred:

  • DON’T uninstall the Thread application on your iPad. Doing so will remove any work not yet synced to the server.

  • DO create your own data backup to iCloud or iTunes. See section below, “How to perform your own data backups.”

Things to Consider

These are not sequential steps, any may help identify or resolve an issue.

  • Can you get online using other apps on the same iPad?

  • Is your location experiencing WiFi or internet problems?

  • Are other team members having problems syncing in Thread?

  • Retry after updating to the most current version of Thread in the App store.

  • Close Thread completely by double-clicking the iPad home button, then swiping up on the app card. Reopen Thread and retry.Report the Problem

  • Sign out of Thread by:

    • Tapping the settings gear and Sign Out

    • Sign in again (Use the same credentials/team) and retry.

  • Retry after powering off and restarting your iPad.

Report the Problem

Please contact Thread if there is a reliable internet connection and assistance is needed, by:

  1. Tapping the question mark (?) icon in the upper right-hand corner of the Thread application screen.

  2. Tap Chat With Us.

  3. Let us know the date and time of the last sync as reported in the alert bar, along with results from the "Things to check / try" section.

If issues also prevent users from contacting us in the Thread application, chat us from our website ( This submits questions anonymously (without user data), so be sure to include your name, organization, and how to contact you, in addition to submitting a detailed description of the issue(s).

It is recommended to perform your own data backups in addition to the two automated methods provided. Adding this step will prevent data loss if a device is damaged or lost, or if the Thread application or team data is accidentally removed from the iPad before a data sync occurs.

Follow these instructions from Apple to backup data regularly to iCloud or iTunes -
