Cookie Policy

Below is everything we set, grouped by whether it depends on your Accept/Decline choice further down this page.

Running the site (always on) — these don't involve Meta and aren't affected by your cookie choice:

• cookie_consent — remembers your Accept/Decline choice itself, so we don't ask again every visit.
• la_email — set once you've signed up or ordered, so we know not to show you the same signup prompt again.
• la_ref — records a referral code if you arrived via a friend's link.
• la_archive_headline — remembers which version of The Archive page you were shown, for our own testing of what works.
• A couple of small cookies that remember whether you've already seen or closed our newsletter popup.
• Your shopping cart — kept in your browser's local storage, not a cookie, so it survives a page refresh.
• la_pricing_visitor — a random, first-party identifier that keeps you in the same version of a pricing test and prevents prices changing between product, cart and checkout. It contains no name, email or advertising ID and is retained for up to 400 days.

Our own campaign measurement (always on) — also not shared with Meta by itself:

• la_attrib — if you arrive via a link with tracking parameters (for example, from one of our ads or emails), we note which campaign and creative brought you here, and the page you landed on. This is our own record for working out which of our campaigns actually lead to a sale. Kept for 90 days.

If you clicked through from a Meta ad specifically, its click reference is advertising data. We do not store that reference unless you have accepted advertising cookies, and we remove it if you later click Decline.

Private site statistics — on unless you opt out — Lost Axis counts page and product views, cart and checkout actions, purchases, section interactions, campaign names, referrer domains, approximate country, device class and browser family. We use these statistics only to understand and improve this website. They stay within Lost Axis and are not used to identify you, build a profile or target advertising. They do not contain advertising click IDs, names, email or postal addresses, full IP addresses, or a persistent visitor identifier.

A random session identifier and a small retry queue exist only in session storage and are not reused in a later browser session. Anonymous session events are retained for 13 months so Lost Axis can inspect complete journeys, then converted to daily aggregate totals and deleted. Use Cookie Preferences to turn Private site statistics off or back on. Turning them off stops new events at once and clears the current statistics session from this device. Rejecting advertising cookies does not erase or disable these private aggregate statistics.

Advertising measurement — only if you accept, below — with your permission, we use two connected tools from Meta Platforms, Inc. so we can tell whether our Facebook and Instagram ads are working:

• Meta Pixel — code that runs in your browser and tells Meta when you view a page or take an action, such as joining our list. It sets two cookies of its own, _fbp and _fbc, so Meta can recognise your browser again later.
• Meta Conversions API — the same kind of event, sent directly from our own server rather than your browser. We use it as a backup for the Pixel, since browsers increasingly block that kind of script. It includes a scrambled (technically: cryptographically hashed) version of your email address, plus your IP address and browser type, so Meta can still match the event to the right ad — your actual email address is never sent to Meta in readable form, but this is not anonymous data: it is designed specifically to be matched back to you.

With the same permission, the OpenAI Ads Measurement Pixel records completed purchases so we can measure ads shown in ChatGPT. The purchase event contains the order value, currency, product identifiers and an order-based event identifier; we do not explicitly include your name, email, delivery address or payment details in that event. The pixel uses the first-party cookies __oppref (up to 30 days) and __obref (up to 365 days).

With that permission, the Google Ads tagrecords page visits and advertising attribution so we can measure and improve our Google advertising. Google may set advertising cookies, including cookies whose names begin with _gcl_. After Stripe confirms a successful payment, the tag also records a purchase conversion containing the order value, currency and a Stripe transaction identifier; it does not include your name, email, delivery address or payment details. The Google library is not requested until you accept, and withdrawing consent switches its advertising storage and personalisation signals back off.

None of these measurement tools runs — in your browser or from our server — unless you have clicked Accept. If you click Decline, or simply haven't answered yet, they stay off.

Data collected by Meta's tools is processed by Meta under its own privacy policy, and cookies it sets are generally kept for up to 180 days. Google and OpenAI process the advertising measurement and attribution data collected by their tags under their respective privacy policies.

We remember the choice you made the first time you visited — both in your browser and, so our server can respect it too, in a matching cookie — for up to 180 days. You can review or change it at any time using Cookie Preferences in the footer of every page, or right here, without needing to clear your browser or hunt for a settings menu.

Beyond the Cookie Preferences link above, you can also control cookies more broadly:

• Browser settings — most browsers allow you to block or delete cookies through their settings menu. Consult your browser's help documentation for instructions.
• Facebook ad preferences — you can manage how Meta uses your data for advertising by visiting your Facebook Ad Preferences settings.
• Your Online Choices — visit youronlinechoices.com to opt out of behavioural advertising from participating companies.

Disabling cookies may affect the functionality of certain features on our site.
