What happens after the trial on lightroom mobile ends?

I have the android v5.0 of LR mobile. 

I've tried to read all the posts regarding the trial but there are too many! What will happen when the trial ends? Will I be able to use LR on my phone as I did before? With the option of paying a monthly subscription for premium features, that is. Will I lose my pics, presets I purchased and uploaded to the app along with the ones I created myself? I don't wanna pay for ACC just to use the app every once in a while. And I truly don't wanna struggle to find a replacement for the Lightroom app. 

Thank you all in advance for all your replies.
