Example Configuration

🎛️ Feature Control

Setting	Type	Default	Description
`disable_notes_feature`	Boolean	false	Completely hides the Notes feature
`disable_patterns_feature`	Boolean	false	Completely hides DVR Pattern storage
`disable_in_app_purchases`	Boolean	true	Prevents all IAP (required with agency activation codes)

💡 Best Practices

Data Security: Set disable_notes_feature: true if the agency restricts the "Notes" feature

Password Compliance: Set disable_patterns_feature: true if the agency restricts the "PW/Patterns" feature

Cost Control: In-app purchases are disabled by default for MDM-managed devices. Set to false only if your agency uses individual store purchases.

⚙️ Report Language Settings

Setting	Type	Options	Default
