# Privacy manifest files In SDK source code there is `PrivacyInfo.xcprivacy`, which describes the data the SDK collects and the reasons the required APIs use that data. You can find more information about privacy manifests on the [Apple Developer Documentation](https://developer.apple.com/documentation/bundleresources/privacy_manifest_files). ## Describing data use in privacy manifests Record the categories of data that your app or third-party SDK collects about the person using the app, and the reasons it collects the data. If you [enable]((/docs/sinch-chat/getting-started/ios/configuration-parameters/#disable-some-of-the-features) the option to send voice messages, you **must add** the `NSPrivacyCollectedDataTypeAudioData` data type to your `PrivacyInfo` file. Likewise, if you [enable]((/docs/sinch-chat/getting-started/ios/configuration-parameters/#disable-some-of-the-features) the Share Location option, you **may need to add** `NSPrivacyCollectedDataTypePreciseLocation` data type to your `PrivacyInfo` file, depending on the scenario. If you [enable]((/docs/sinch-chat/getting-started/ios/configuration-parameters/#disable-some-of-the-features) the option to send photo or video messages, you **must add** the `NSPrivacyCollectedDataTypePhotosorVideos` data type to your `PrivacyInfo` file. You can find more information about describing data use in privacy manifests on the [Apple Developer Documentation](https://developer.apple.com/documentation/bundleresources/privacy_manifest_files/describing_data_use_in_privacy_manifests). An example of a privacy manifest is given below: ```swift NSPrivacyCollectedDataTypes NSPrivacyCollectedDataType NSPrivacyCollectedDataTypeAudioData NSPrivacyCollectedDataTypeLinked NSPrivacyCollectedDataTypeTracking NSPrivacyCollectedDataTypePurposes User can send voice message to the other user using chat. NSPrivacyCollectedDataType NSPrivacyCollectedDataTypePhotosorVideos NSPrivacyCollectedDataTypeLinked NSPrivacyCollectedDataTypeTracking NSPrivacyCollectedDataTypePurposes User can send his photos or videos to the other user using chat. NSPrivacyCollectedDataType NSPrivacyCollectedDataTypePreciseLocation NSPrivacyCollectedDataTypeLinked NSPrivacyCollectedDataTypeTracking NSPrivacyCollectedDataTypePurposes User can send his location to the other using chat. ``` Now that you have assigned permissions and populated the privacy manifests, you can [show the chat]((/docs/sinch-chat/getting-started/ios/showing-chat/).
