Once the application is installed on a cell phone or tablet it will start to collect data from the device. And, on regular intervals it tries to upload this data to your Private Area. The FreeAndroidSpy Private Area is the website in which you can securely access your data as many times as you wish, any time. For more information on the Private Area, please refer to the "Working with the Private Area" section in the FAQs.
The application works completely invisible and cannot be seen by the user of the phone. When FreeAndroidSpy is uploading your data to your Private Area all communications are secured by the industry standard SSL/TLS and the data remains encrypted, hence no one else except you has access to your data.
Usually the application will not drain the battery and it will use up to 3% of it.
