Opt-out

When Opt-out is enabled, the SDK stops sending all events.

Configure at Initialization

Swift

let config = HackleConfigBuilder()
    .optOutTracking(true)
    .build()

Hackle.initialize(sdkKey: YOUR_APP_SDK_KEY, config: config) {
    // SDK ready to use.
}

Objective-C

Runtime Opt-out Control

Swift

hackleApp.setOptOutTracking(optOut: true)   // activate
hackleApp.setOptOutTracking(optOut: false)  // deactivate
let isOptOut = hackleApp.isOptOutTracking   // query (property, not method)

Objective-C

Persistence Management

The Opt-out state changed at runtime is reset to the value configured in the initialization Config on app restart.

To persist the state across app restarts, you must implement your own save and restore logic.

Swift

func saveOptOutState(_ optOut: Bool) {
    UserDefaults.standard.set(optOut, forKey: "hackle_opt_out")
    hackleApp.setOptOutTracking(optOut: optOut)
}

func getOptOutConfig() -> HackleConfig {
    let optOut = UserDefaults.standard.bool(forKey: "hackle_opt_out")
    return HackleConfigBuilder()
        .optOutTracking(optOut)
        .build()
}
