Web Browser Cookies

Is it possible to interact with the built-in browser’s cookies? I have a website that currently has persistent login for users, and I want players to not have to log in every time when inside the built-in browser. The browser seems to clear all cookies and storage when it closes.

My game sends http requests to my website to store user data, so I have access to the cookie containing an access token sent from the server, but I need a way to be able to access the browser’s cookies.

I’m also open to any other suggestions. I’m looking to display charts based on the current user’s data, so if there’s a way to send an html file or something that I could render inside the game, that could work too.

Thanks,
Mark
