Is it worthwhile to offer a "recover your status" functionality for a paid version in phone app?

I'm thinking about offering this functionality for the paid version of an app, I think it would take around to 80 hours to achieve the development of such functionality.

To better clarify what the functionality is about, it would allow an user to uninstall its app, be it because he has got tired from it, it fails for whatever reason and the user wants to reinstall it, the user needs to make space in his phone for a certain temporal app and it needs my app to make enough space for that temporal app.

It's to notice that in my app, you may lose several weeks of app use if you decide to uninstall it, so it's not that bad a functionality, but even then, I think cases like the previous ones are not common enough to compensate for the effort of developing such functionality.

Do you think that functionality is worthwhile to develop or do you think that it wouldn't compensate?
