Cookie Policy

How we use cookies and similar technologies on this site.

We’re finalising this policy ahead of launch. Last updated 14 September 2026.

What cookies are

Cookies are small text files a website stores on your device. Similar technologies (such as your browser’s local storage) work in the same way. We use them to keep you signed in, remember your choices, and (only with your consent) understand how the site is used. This policy sits alongside our Privacy Policy.

Strictly necessary

These make the site work: staying signed in, your basket, and the choices you make before you have an account. They do not require consent.

Name	Purpose	Type	Lifetime
`sb-…-auth-token (and numbered parts)`	Keeps you securely signed in to your account. Set by our authentication provider (Supabase).	Cookie	Rolling — refreshed while you use the site; removed when you sign out
`wtr_app`	Set briefly when you arrive from our mobile app, so we can return you to the app after checkout.	Cookie	30 minutes, or removed as soon as checkout finishes
`netcompetitions.cart.v1`	Holds the items in your basket before you are signed in, so they are still there when you come back.	Local storage	Until you clear it or sign in (it then moves to your account)
`netcompetitions_pending_interests`	Remembers the categories you pick before you create an account, so they are not lost when you sign up.	Cookie	30 days, or removed once your account is created
`netcompetitions_pending_watches`	Remembers competitions you choose to watch before you create an account, so they are not lost when you sign up.	Cookie	30 days, or removed once your account is created
`netcompetitions_analytics_consent`	Remembers whether you accepted or declined optional cookies, so we do not ask again.	Cookie	1 year
`nc_device_signal_at`	Records when we last ran our fraud-prevention check on this device, so we do not repeat it on every page. Holds a time only, nothing about you or the device.	Local storage	Until you clear it

Functional

These remember choices you have made so the site behaves the way you left it. They do not require consent.

Name	Purpose	Type	Lifetime
`nc_display`	Remembers your display preferences: how many competition cards you prefer per row on smaller screens, and the colour theme of your For You feature.	Cookie	1 year
`nc_draw_sound`	Remembers whether you turned the sound on or off on the draw page.	Local storage	Until you clear it
`nc_recent_searches`	Keeps your last few searches on this device so you can pick them again. Never sent to us.	Local storage	Until you clear it
`netcompetitions_signup_attribution`	Remembers which page you started from during this visit, so that if you create an account we can record how you found us.	Session storage	This visit only — cleared when you close the browser tab
`netcompetitions_referral`	If you arrived through a friend’s referral link, remembers their code so they get credit if you sign up.	Local storage	30 days
`netcompetitions_affiliate`	If you arrived through a partner’s link, remembers their code so they get credit if you sign up.	Local storage	30 days

Campaign attribution (consent required)

If you reach us by scanning a leaflet or poster, or through one of our campaign links, we would like to remember which one so we can see what works. This cookie is only set if you have accepted optional cookies. It is ours alone and is never shared with advertisers.

Name	Purpose	Type	Lifetime
`nc_mc`	If you arrived by scanning one of our leaflets, posters or campaign links, remembers which one, so we can see which campaigns work. Only set if you have accepted optional cookies.	Cookie	30 days

Analytics (consent required)

With your consent, we use a privacy-focused analytics provider (hosted in the EU) to understand how the site is used so we can improve it. These cookies are only set after you accept them, and we do not use them for advertising. If you decline, they are not set.

Name	Purpose	Type	Lifetime
`ph_…_posthog`	Our privacy-focused analytics (PostHog, hosted in the EU) uses this to tell one visit from another so we can understand how the site is used. Only set if you have accepted optional cookies. Not used for advertising.	Cookie	1 year

Managing your choices

When you first visit, we ask whether to allow optional cookies. You can accept or decline, and change your mind later. You can also block or delete cookies through your browser settings, though blocking necessary cookies may stop parts of the site working (for example, staying signed in).

We only set non-essential cookies and storage with your consent, as required by the Privacy and Electronic Communications Regulations (PECR) and the UK GDPR. This page is generated from the same list our website code uses, so it stays complete as the site changes.
