為協助您遵守美國州級隱私權法律，Google Mobile Ads SDK 支援使用 Google「受限的資料處理 (RDP)」參數，用來指定是否啟用 RDP。在適用的美國州別，Google 也支援全球隱私權平台 (GPP)。當 Google Mobile Ads SDK 採用了任一信號，在為您提供服務時，SDK 將限制特定專屬 ID 並處理其他資料。

Google also supports the\n\n[Global Privacy Platform](//support.google.com/admob/answer/14126918)\n\n(GPP) for applicable US states. When the Google Mobile Ads SDK uses either\nsignal, the SDK restricts certain unique identifiers and other data is processed\nin the provision of services to you.\n\nYou must decide how restricted data processing can support your compliance plans\nand when to enable. Determine whether to use the RDP parameter\ndirectly or signaling consent and privacy choices with the\n[GPP Specification](//github.com/InteractiveAdvertisingBureau/Global-Privacy-Platform).\n\nThis guide helps you enable RDP on a per-ad request basis and use the GPP\nsignal.\n\nEnable the RDP signal\n\nTo notify Google to enable the RDP signal, write the key `gad_rdp` with a value\nof `1` to\n[`SharedPreferences`](//developer.android.com/reference/android/content/SharedPreferences)\nstorage. Google Mobile Ads SDK reads the `gad_rdp` key during ad loading: \n\nJava \n\n SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(context);\n sharedPref.edit().putInt(\"gad_rdp\", 1).apply();\n\nKotlin \n\n val sharedPref = PreferenceManager.getDefaultSharedPreferences(context)\n sharedPref.edit().putInt(\"gad_rdp\", 1).apply()\n\n\u003cbr /\u003e\n\n| **Tip:** You can use [network tracing](/admob/android/network-tracing) or a proxy tool such as [Charles](/admob/android/charles) to capture your app's HTTPS traffic and inspect the ad requests for a `&rdp=` parameter.\n\nUse the IAB GPP Signal\n\nIf you collect consent decisions with a consent management platform or your own\ncustom messaging, the Google Mobile Ads SDK respects GPP signals written to\nlocal storage. The User Messaging Platform (UMP) SDK supports writing the GPP\nsignal. To gather US state consent, see\n[US IAB Support](/admob/android/privacy/us-iab-support)."]]
