Read that as description
Those three are a picture, not a full accounting, and the list has no edges drawn around it. It also claims nothing about the technical setup sitting behind the site, so please do not read it as one.
Straight answer
This page is about the information that may be around when people use Here2Eat. It skips the legal voice on purpose. An explanation you have to decode first is not doing its job.
It is here for anyone who wants to know how that information is treated in general terms. Someone standing on a pavement reading a place card, someone who runs a kitchen and turns up on one of those cards: same page, same answer for both of you.

The broad shapes
Three broad kinds, pitched at the level you would use telling somebody about it on the walk over. Nothing below is a specification and nothing below needs a glossary.
Those three are a picture, not a full accounting, and the list has no edges drawn around it. It also claims nothing about the technical setup sitting behind the site, so please do not read it as one.
The reason
Because a page has to load, a list of nearby places has to come back while you are still standing there, and a message somebody sends has to reach a person who can read it.
That is the honest length of the answer. Information is handled so the site works, so the pages hold together across visits, and so a reply is possible when you write in. Nothing here is pointed at some other purpose waiting quietly behind those.
Which loops straight back to what this site is for. You are out, you are hungry, and you want one nearby place that fits the next few minutes, chosen without opening five tabs first. Everything the site does with anything is aimed at making that choice arrive quickly and hold up when you walk to it.
Care and change
Whatever is around gets sensible care, scaled to what this service really is: a small, quick way to settle where to eat while you are already out on your feet.
This wording can change. Sites get rebuilt, the way a thing works gets adjusted, and the sentences describing it have to follow along. When it does change, whatever stands here on the day you read it is the wording that counts for your visit. No older copy is kept alive somewhere behind it.
So if you ever want to know where things stand, come back and read this page again. It carries the current text, and the date near the top says when that text was last touched.
Ask
Something on this page leaves you with a question? Use the same way in that the rest of the site already points at, the contact address sitting in the footer of every page including this one. No separate channel gets opened up here, because one route in is easier for everybody to remember.
One thing helps a lot: put the word privacy at the front of what you write. Flagged that way it gets read as a privacy question, instead of sitting in the pile with notes about a spot worth adding or a card that needs correcting.
