How to keep Checkboxes checked even after leaving the page/site?

Hi, I have created a “test” database and linked a checkbox to this database, and have created a dataset to try to link to this as well. I am still not having any luck with keeping my checkboxes in a checked state once leaving the page and returning again. I have no idea what I am doing, I have researched all of the Corvid forums and aticles about API and watched tutorial videos but I can’t seem to find anything pertaining to what i would like to do. plese help!
