Google Apps Script

[Haider1]

I recently created a project on Google Apps Script through which employees of a company can know their salaries, and more than 50,000 thousand people will use it. The first question is: If the number of users of the project that I created increases, will it lead to the project being disrupted or causing any confusion in it? Secondly, I fear that Apps script will be stopped in the future and my project will collapse.
