Purpose of Obtaining Permission

To provide you with accurate weather services, we may request to obtain your device's location permission.

• Precise Location: It is only temporarily obtained when you actively enable the Precise Location Weather function, to provide minute-level precipitation, approaching meteorological warnings and other refined services for your current location. Data will be processed immediately after use and will not be stored for a long time.

Permission Authorization and Withdrawal

You can independently choose to allow or deny the location permission request when using weather-related functions for the first time.
