Hello,

Thank you for your response and for providing this information.

However, upon further review we noticed that your app does not comply with the following guideline:

Guideline 5.1.5 - Legal - Privacy - Location Services

Your app uses background location services but does not clarify the purpose of its use in the location modal alert as required in the iOS Human Interface Guidelines.

Please see attached screenshots for details.

Next Steps

To resolve this issue, please revise the NSLocationAlwaysUsageDescription value in the Info.plist to specify the intended purpose of using the user's location while the app is in the background.

Resources

For additional information and instructions on configuring and presenting an alert, please review the Requesting Permission section of the iOS Human Interface Guidelines and the Information Property List Key Reference.

We look forward to reviewing your revised app.

Best regards,

App Store Review
