For an introduction to consent\n\u003e mode, read [Consent mode\n\u003e overview](/tag-platform/security/concepts/consent-mode).\n\nGoogle Analytics offers consent mode to adjust how your SDK behaves based on the\nconsent status of your users. You can implement consent mode in a basic or\nadvanced way. If you aren't sure whether to implement basic or advanced consent\nmode, learn more about [basic versus advanced consent\nmode](/tag-platform/security/concepts/consent-mode#basic-vs-advanced) and check\nwith your company's guidelines. \nAdvanced consent mode Basic consent mode \niOS Android\n| **Important** : Consent mode for apps was updated Oct 30th 2023 and now contains two additional parameters.

Learn more about Google's [Updates to consent mode for traffic in European Economic Area (EEA)](https://support.google.com/tagmanager/answer/13695607).\n\nBefore you begin\n----------------\n\nBefore you can manage user consent, you need to implement:\n\n- [Google Analytics for Firebase SDK](https://firebase.google.com/docs/analytics)\n- A consent settings banner to capture user consent\n\n | **Tip:** If you don't want to implement consent settings yourself, consider using a consent management platform (CMP).\n\nSet up consent mode\n-------------------\n\nTo set up consent mode, you need to:\n\n1. [Set the default consent state](#default-consent).\n\n### Set the default consent state\n\nBy default, no consent mode values are set. To set the default consent state for\nyour app:\n\n1. Open your app's [info.plist](https://developer.apple.com/documentation/bundleresources/information_property_list) file.\n2. Add the consent mode key-value pairs. The key describes the [consent\n type](/tag-platform/security/concepts/consent-mode#consent-types) and the\n value indicates consent state. Values can either be `true`, meaning consent\n was granted, or `false`, meaning consent was denied.\n\n In accordance with the updates to consent mode for traffic in\n European Economic Area (EEA), a value of `eu_consent_policy` can be set\n for `ad_user_data` and `ad_personalization`, meaning consent is denied only\n for users in regions subject to the EU User Consent Policy.\n\n Set the following:\n - `GOOGLE_ANALYTICS_DEFAULT_ALLOW_ANALYTICS_STORAGE`\n - `GOOGLE_ANALYTICS_DEFAULT_ALLOW_AD_STORAGE`\n - `GOOGLE_ANALYTICS_DEFAULT_ALLOW_AD_USER_DATA`\n - `GOOGLE_ANALYTICS_DEFAULT_ALLOW_AD_PERSONALIZATION_SIGNALS`\n3. Save your changes. Next, implement the mechanism to update consent values.\n\nFor example, to set all grant consent for all parameters by default: \n\n \u003ckey\u003eGOOGLE_ANALYTICS_DEFAULT_ALLOW_ANALYTICS_STORAGE\u003c/key\u003e \u003ctrue/\u003e\n \u003ckey\u003eGOOGLE_ANALYTICS_DEFAULT_ALLOW_AD_STORAGE\u003c/key\u003e \u003ctrue/\u003e\n \u003ckey\u003eGOOGLE_ANALYTICS_DEFAULT_ALLOW_AD_USER_DATA\u003c/key\u003e \u003ctrue/\u003e\n \u003ckey\u003eGOOGLE_ANALYTICS_DEFAULT_ALLOW_AD_PERSONALIZATION_SIGNALS\u003c/key\u003e \u003ctrue/\u003e\n\n### Update consent\n\nTo update consent values after an app has launched, call the\n[`setConsent`](https://firebase.google.com/docs/reference/android/com/google/firebase/analytics/FirebaseAnalytics#setConsent) method.\n\nThe value set by the `setConsent` method overrides the default setting and\npersists across app executions. The value remains in that state until\n`setConsent` is called again, even if a user closes and reopens the app.\n`setConsent` only updates the parameters you specify.\n\u003e If a user withdraws their previously given consent for Analytics or Ad\n\u003e storage, Google Analytics deletes all user properties, including consent for\n\u003e [`ad_personalization`](https://developers.google.com/tag-platform/security/concepts/consent-mode#consent-type).\n\u003e To preserve the user's consent choice for ad personalization, restore the\n\u003e previous value for ad personalization using `setConsent`\n\u003e\n\u003e ([Swift](https://firebase.google.com/docs/reference/swift/firebaseanalytics/api/reference/Categories/FIRAnalytics(Consent)#setconsent_:)\n\u003e \\| [Obj-C](https://firebase.google.com/docs/reference/ios/firebaseanalytics/api/reference/Classes/FIRAnalytics#+setconsent:))\n\u003e .\n\nThe following example shows the `setConsent` method updating the different\nconsent values to `granted`: \n\n### Swift\n\n Analytics.setConsent([\n .analyticsStorage: .granted,\n .adStorage: .granted,\n .adUserData: .granted,\n .adPersonalization: .granted,\n ])\n\n### Objective-C\n\n [FIRAnalytics setConsent:@{\n FIRConsentTypeAnalyticsStorage : FIRConsentStatusGranted,\n FIRConsentTypeAdStorage : FIRConsentStatusGranted,\n FIRConsentTypeAdUserData : FIRConsentStatusGranted,\n FIRConsentTypeAdPersonalization : FIRConsentStatusGranted,\n }];\n\nIf a user decides to revoke their consent, make sure you update the consent\nstates accordingly\n\n\nUpgrade to consent mode v2\n--------------------------\n\nAs a part of Google's ongoing commitment to a privacy-safe digital advertising\necosystem, we are strengthening the enforcement of our [EU user consent\npolicy](https://www.google.com/about/company/user-consent-policy/).\n\nLearn more about Google's [Updates to consent mode for traffic in European\nEconomic Area (EEA)](https://support.google.com/tagmanager/answer/13695607).\n\nConsent mode users need to send two new parameters in addition to ad storage and\nanalytics storage:\n\n1.

[Enable verbose logging](https://firebase.google.com/docs/analytics/events?platform=ios#view_events_in_the_xcode_debug_console) on your device.\n2. In the Xcode debug console, look for:\n\n - `ad_storage`\n - `analytics_storage`\n - `ad_user_data`\n - `ad_personalization`\n\n For example, if Ad storage are enabled, you'll see the following message: \n\n ad_storage is granted."]]
