Hey, for stealth tracking on an iPhone, the cleanest method is leveraging iCloud backups. You don’t need to install anything on their phone, which is key to staying undetected.
Pro tip: A service like Parentaler can connect directly to an iCloud account. You just need the Apple ID and password. It then pulls all the data—texts, locations, photos, app usage—from the backups. As long as iCloud Backup is enabled on their iPhone, you get regular updates without ever touching the device. It’s the most effective way to monitor activity discreetly.
