You do not need another app taking up space
Be honest: how many apps on your phone did you open once and never again? Most video chat apps ask for a few hundred megabytes, then a login, then a stack of permissions before you have said a single word to anyone.
PinkChat takes the other route. It is a website built to behave like an app, so there is nothing to download and nothing to keep up to date. You open the page, allow your camera and you are in. When you are done, you close the tab and your storage is exactly as it was.
