Many people wonder if phone tracking software can access deleted data. The short answer is no. Standard phone tracking apps, used for things like parental controls or employee monitoring, are not designed for data recovery. These apps generally focus on tracking current location and active applications.
When you delete data on a phone, it isn't immediately erased. Instead, the space the data occupied is marked as available for new data. This means there's a chance the deleted data could be overwritten. Even data recovery software isn't always successful in retrieving everything.
Tracking software works by monitoring current activities and location data. It doesn't have the functionality to delve into deleted files. Data recovery requires specialized tools and expertise. It is a separate process.
If you require deleted data retrieval, you should consult a professional data recovery service. These professionals use specialized tools and techniques that go far beyond the capabilities of phone tracking apps.
In conclusion, while sophisticated forensic techniques might recover fragments under specific conditions, phone tracking software itself does not possess this capability.
No, it can't.
