Can a software can keep track of task you are doing. Foe eg. if i use Boilsoft for joining the videos, can developer know what I am doing. Same case for Mp3 cutter. Thanks
No. There's no provision for anonymously sending personal information to the software developer.
If there's any, it is needed that the user must approve it.
Adding to it, bugs and update checks can be done in the background, which can be changed in the settings section of the software.
