Cookie policy

Cookies are small files a website keeps in your browser. This page lists every cookie, and everything else, that The Wolfsbane Library keeps in your browser, why, and for how long. Our Privacy notice explains what we do with personal data more generally.

Strictly necessary

These make the shop work, so they are always on. They are set only by our own website, and none of them tracks you across other sites.

Name	What it does	How long
wl_ship	Remembers the destination you ship to, so prices are in your currency	One year
wl_track	Lets this browser show an order you looked up, without asking again	One hour
wl_orders	Keeps the references of orders placed in this browser (and nothing else), so you can find them again under Track an order. You can remove it from the order page	One year
wl_fix	Lets this browser correct the email address of an order it found through "Didn't get your email?"	30 minutes
wl_consent	Remembers what you allowed below, with a random reference to the record of your choice (which holds nothing that identifies you)	Six months

The website also keeps these in your browser's own storage, which never leaves your device:

Name	What it does	How long
Your basket	The books in your basket	Until you empty it or clear your browser's data
Checkout details	What you typed at checkout, so it is still there if you go back to change your basket	Until you close the tab

Only if you allow them

The cookie banner asks for each purpose below separately, and none is switched on until you choose. "Reject all" is one click, just like "Accept all", and closing the banner is never taken as agreement.

Measuring visits

Name	Set by	What it does	How long
_ga, ga*	Google Analytics	Tells visits apart, to count how the shop is used	Two years

Advertising and partners

Name	Set by	What it does	How long
_gcl_au, gcl*	Google Ads	Links an order to the advert that led to it	90 days
wl_aff	Our website, for impact.com	Keeps the click reference of the affiliate partner who sent you, so they can be paid for an order	The referral period, usually 30 days
wl_conv_*	Our website (browser storage)	Makes sure an order is counted only once	Until you clear your browser's data

Google may also set cookies on its own domains when it measures an advert. See how Google uses cookies.

Videos and audio from other sites

Some Marginalia articles include a player from YouTube (in its privacy-enhanced mode), Vimeo, Spotify or SoundCloud. Until you allow this purpose, or press play on one player, nothing is loaded from those services: a notice stands in its place, with a link to open it on the service's own site instead. Once a player is loaded, the service that hosts it receives your IP address and may set its own cookies, under its own policy: YouTube (Google), Vimeo, Spotify, SoundCloud.

Signing in to the back office

Our staff's sign-in uses two more strictly necessary cookies, which visitors never get: one keeps a member of staff signed in (it ends after 30 minutes without use, and after eight hours at most), and one remembers a device they chose to trust, for 30 days.

Changing your mind

Use "Cookie settings" at the foot of every page to change your choice at any time, purpose by purpose: withdrawing is as easy as agreeing. When you withdraw a purpose, we remove its cookies from our website and stop what it was running (a player already playing stops when the page reloads). Your choice is asked for again after six months, or sooner if what we ask for changes. You can also block or delete cookies in your browser's settings: the shop still works without the optional ones, but it needs the strictly necessary ones to remember your basket, your destination and your orders.
