SDK opt-out (e.g. GDPR)

Starting with Batch 1.12, you can now opt-out from the SDK.

If you plan to send personal user data and have to comply with EU's GDPR, any other data privacy law or simply want to give your users more control regarding their privacy, these methods will help you plug your consent screen to Batch.

There are two SDK operation modes:

  • SDK enabled by default, opting-out required via an explicit method call: this is the default mode.
  • SDK disabled by default, opting-in required

Important: On iOS, disabling the SDK won't disable push notifications if Batch already has a valid token. In case you want to implement a notification opt-out, you will need to direct users to iOS' settings by using the [BatchPush openSystemNotificationSettings](Objective-C) or the BatchPush.openSystemNotificationSettings() (Swift) method.

Opting-out

In order to opt-out from SDK, simply call:

  • Objective-C
  • Swift
[Batch optOut];

Opting out will:

  • Prevent [Batch startWithAPIKey:] from starting the SDK
  • Disable any network capability from the SDK
  • Disable all In-App campaigns
  • Make the Inbox module return an error immediatly
  • Make any call to -[BatchUserDataEditor save] do nothing
  • Make any "tracking" methods from BatchUser ineffective

Even if you opt-in afterwards, data generated (such as user data or tracked events) while opted out WILL be lost.

You can also wipe the local SDK data:

  • Objective-C
  • Swift
[Batch optOutAndWipeData];

This will wipe the data locally and request a remote data removal for the matching advertising ID/Custom User ID. Batch will blacklist the advertising and the Custom User ID for one month following the data removal. Batch will also discard the data sent from the Custom Data API for that specific Custom User ID. The Inbox feature will no longer work if you were relying on the Custom User ID.

Note: Opting out is not possible while the SDK hasn't started. Make sure you've called [Batch startWithAPIKey:] beforehand.

Disabling the SDK by default

In order to disable the SDK by default, you need to add a key called BATCH_OPTED_OUT_BY_DEFAULT with a true boolean value to your Info.plist.

Opting-in

Once you've opted-out (either programatically, or by default), you can re-enable the SDK by calling the following:

  • Objective-C
  • Swift
[Batch optIn];
[Batch startWithAPIKey:@"YOUR_API_KEY"];

Note: Even if you've already done so before opting-out, you are required to call [Batch startWithAPIKey:] or the SDK won't work until the next start.
