Yes, it would be a great idea to update the wording as there is no way to derive that from the current one.

Even being sympathetic, my thought reading this was "probably bad code quality/rotten core despite the great feature set".

You can have a "History/Background/Origin" section where you put exactly what you wrote in your comment and it will be fine.

This notwithstanding, thank you very much for developing this app! I will look into deploying it on my server, it will be of great help to people around me who often need manipulating PDFs but are not super technical!
