This page lists every cookie and browser storage item used on centenaryph.com, what it does, and how long it lasts.
Cookies are small text files a website saves in your browser. Similar technology, called browser storage, lets a site remember things on your device. Some are needed for the site to work; others are optional.
These keep the site working and secure. They are always on, because sign-in and the admin area cannot work without them.
| Name | Purpose | How long |
|---|---|---|
cph_session | Keeps you signed in to your account while you browse. | Until you close your browser or sign out |
cph_remember | Keeps you signed in on this device if you tick "Remember me" when signing in. | Up to 30 days |
cph_admin_session | Signs in CPH staff to the admin area. Not used for visitors. | Until the staff member signs out or closes the browser |
These are saved only on your device and are not sent to us until you submit an order.

cph-catalog-view | Remembers whether you prefer the grid or list view in the catalogue. | Until you clear your browser data |
cph-cookie-consent | Remembers whether you accepted or rejected analytics cookies, so we do not ask on every page. | Until you change it or clear your browser data |
cph-theme | Remembers the site's colour theme. | Until you clear your browser data |
We use Google Analytics to understand which pages help people find books, so we can improve the site. These cookies are only set if you choose Accept. If you reject them, Google Analytics does not store cookies on your device; Google may still receive basic, cookieless signals that a page was viewed, without identifying you.
