Quick guidance for common questions, plus a direct line to the team when you need it.

For LeanLine on iPhone

Account and recovery

LeanLine may start with an anonymous account. Protecting it with Sign in with Apple helps preserve access when you reinstall the app or change devices. If you already have LeanLine data, use the account-protection option from that existing account rather than starting over.

Purchases and LeanLine PRO

Purchases are billed through the Apple Account shown in the App Store. If PRO is not recognized, confirm that you are using the same Apple Account, reopen LeanLine with an internet connection, and use Restore Purchases from the PRO screen.

Apple Health and weight data

Apple Health access is optional. You can review or change LeanLine’s Body Mass permissions in the Health app or iOS Settings. Raw weight logs remain local to your device unless you deliberately export or share them.

Notifications

If reminders or social alerts are missing, check iOS Settings → Notifications → LeanLine. Notifications require permission and an active network connection before LeanLine can register the device for delivery.

Friends, challenges, and Squads

Use exact LeanLine Codes and Squad invite codes, and connect only with people you trust. If social information appears delayed, reopen LeanLine while online. Blocking and reporting tools are available for inappropriate content or abusive behavior.
