We've tested this exact camera against a real ARW sample file and independently verified the shutter count against exiftool — this one is confirmed working.

Shutter count for the Sony A7CR (ILCE-7CR) is read from MakerNote tag 0x9050, decrypted, offset 0x000A in the camera's ARW file metadata — entirely in your browser, the file is never uploaded anywhere.
