Integration

Important

This SDK does not transmit any data to the SDK provider. Therefore, if you use this SDK to collect personal information, you are considered the data processor. The SDK provider is not a data processor or a sub-processor. You must fully inform users and obtain their authorization in accordance with relevant laws and regulations. When informing users, ensure that the SDK provider is not identified as a data processor or a sub-processor.
