Not much. You can try clearing your Safari cache by going to "Settings>Apps>Safari>Clear History and Website Data."
Clear your cache and cookies on iPhone - Apple Support
There's also, in "Settings>Apps>Safari>Advanced>Website Data," lots of stuff kept for individual website.
You can also go to "Settings > General > iPhone Storage," and select an app. You can either "Offload App" which
removes the app and its cache, but keeps the app data, or "Delete App" which dumps the app and its data.
Here's a hint: we are not Apple; folks who read these posts are just users like you. Some of us hang around here from time to time in case our experience may help someone. We don't get paid and we don't have a schedule, and the Apple engineers don’t read this stuff. Choosing a name like Apple_sucs34 won't encourage us to offer any help. In general, when you ask someone for help, Apple, or anybody, really, you're more likely to get results by being polite and serious, and stating your concern without trying to offend people.
