5.5.1 处理隐私数据 示例代码

在准备应用的隐私政策时，你可以使用“协助创建应用隐私政策的工具” [29]。 这些工具以 HTML 格式和 XML 格式输出两个文件 - 应用隐私策略的摘要版本和详细版本。 这些文件的 HTML 和 XML 内容符合 MIC SPI 的建议，包括搜索标签等特性。 在下面的示例代码中，我们将演示此工具的用法，并使用由这个工具产生的 HTML 文件来展示程序隐私策略。

[29] http://www.kddilabs.jp/tech/public-tech/appgen.html

更具体地说，你可以使用以下流程图来确定使用哪个示例代码。

这里，“广泛同意”一词，指代广泛许可，由用户在应用的首次加载时，通过展示和查看程序隐私策略授予应用，用于应用将用户数据传输到服务器。 相反，短语“特定同意”指代在传输特定用户数据之前，立即获得的预先同意。

5.5.1.1 授予广泛同意和特定同意：包含应用隐私政策的应用

要点：

1. 首次加载（或应用更新）时，获得广泛同意，来传输将由应用处理的用户数据。
2. 如果用户未授予广泛同意，请勿传输用户数据。
3. 在传输需要特别细致的处理的用户数据之前获得特定同意。
4. 如果用户未授予特定同意，请勿传输相应的数据。
5. 向用户提供可以查看应用隐私策略的方法。
6. 提供通过用户操作删除传输的数据的方法。
7. 提供通过用户操作停止数据传输的方法。
8. 使用 UUID 或 cookie 来跟踪用户数据。
9. 将应用隐私策略的摘要版本放置在素材文件夹中。

5.5.1.3 不需要广泛同意：包含应用隐私策略的应用

要点：

1. 向用户提供查看应用隐私策略的方法。
2. 提供通过用户操作删除传输的数据的方法。
3. 提供通过用户操作停止数据传输的方法
4. 使用 UUID 或 cookie 来跟踪用户数据。
5. 将应用隐私策略的摘要版本放置在素材文件夹中。

5.5.1.4 不包含应用隐私策略的应用

要点：

1. 如果你的应用只使用它在设备中获取的信息，则不需要显示应用隐私策略。
2. 在市场应用或类似应用的文档中，请注意应用不会将其获取的信息传输到外部。
