Is it correct to keep such logic in the application?

Question

Mobile development

Hello. I myself am a frontend developer and now I am writing a pet project, and since I use firebase, I would like to know whether it will be correct from the point of view of the architecture of mobile applications to do the logic by the type of selection of any information, and even do the same search based on the information entered by the user in the application itself ?
Why I ask, because in the front we transfer all such logic to the server, and since I use firebase, I don’t have a server as such.

Answer 1

I smoked a firebase doc and realized that all the functions that I need are already available (I should have started with this), so I can close the question.
