Español HQ Support

For sign-in, sync, account deletion, or study-data help, open a support request.

Include your device model, operating-system version, app version, what you expected, and what happened. If the problem involves sync, say whether it happens on iPhone, iPad, Mac, or more than one device.

Before contacting support

• Keep the app installed so locally queued changes are not discarded.
• Reconnect to the internet, reopen the app, and allow sync to retry.
• Use Settings to export a copy of your study data when possible.

Never send your password, old-app passcode, authentication token, private database URL, or an unredacted export containing material you do not want support to read.

See the privacy policy for data, retention, export, and deletion details.
