Our anti-lost tracker works with the Find My App and consumes the download of any other app, and the tracker does not store location data and history, and since it is non-encrypted, the private key is not shared in any way, so except The original owner and no one else, including Apple itself, can decrypt the transmitted information, which will protect user privacy.
