Cookie policy
What Dupin stores on your device, why, and how to change it. There are no advertising or cross-site tracking cookies, and analytics only runs if you say yes.
Last updated 4 November 2026
Change or withdraw your choice at any time. It applies straight away.
Your choices
| Category | What it covers | Your consent |
|---|---|---|
| Essential | Signing in, protecting sign-in, remembering your cookie choice | Not needed: the site can't work without them |
| Preferences | Settings you choose yourself, like light mode or starred markets | Not needed: only saved when you change something |
| Analytics | Counting page views, clicks, load speed and errors | Off until you agree |
| Marketing | Advertising, retargeting, cross-site tracking | Not used |
The first time you visit we ask, with Accept all and Reject all side by side. If you don't answer, nothing optional runs. If your browser sends a Global Privacy Control signal, we treat it as Reject all and don't ask. We ask again after 12 months, or sooner if this policy changes in a way that matters.
Cookies

All three are first-party (set by Dupin, sent only to Dupin). We don't set any third-party cookies.
Stored in your browser
These stay on your device (local or session storage) and are only written when you use the feature. Starred markets are also saved to your account when you're signed in, so they follow you between devices.
| What | Why | Category | Lasts |
|---|---|---|---|
| Light mode | Shows the site in the theme you picked | Preferences | Until you switch back or clear it |
| Starred markets | Your Favourites view on match pages | Preferences | Until you clear it |
| Favourite leagues | Pins your leagues to the top of fixtures | Preferences | Until you clear it |
| Expanded leagues | Keeps open the leagues you opened | Preferences | Until you close the tab |
| Pinned matches and layout | Your Multiview board | Preferences | Until you clear it |
| Display filters | My markets, insight market filter and sort order | Preferences | Until you clear it |
| Live alerts seen | Keeps a live match's alert timeline in place if you reload | Preferences | Until you clear it |
| Install prompt dismissed | Stops the "Get the Dupin app" prompt reappearing after Not now | Preferences | 14 days |
You can wipe all of these at once with Clear saved preferences in , or from your browser's site data settings.
Analytics
With your consent, we count page views, clicks on buttons and links, time on a page, page load speed and script errors, so we can see which features are used and fix what breaks. We built this ourselves; it isn't a third-party tool.
- Nothing is stored on your device for analytics: no cookie, no local storage.
- Visitors are counted with a one-way code made from your IP address and browser, which changes every day. We never store the IP address itself, and visits can't be linked across days or to other sites.
- We record device type (phone, tablet or desktop), country, and the site that linked you to us.
- When you're signed in, events are linked to your account.
- Nothing is shared with or sold to advertisers. Events are deleted after 13 months.
Whatever you choose, we record failed and blocked sign-in attempts to protect accounts, and a record of your cookie choice itself (what you chose and when, kept 2 years) so we can show we asked.
Other services
| Service | When | What it means |
|---|---|---|
| Stripe | Only when you pay for Pro | Checkout happens on Stripe's own site, which sets its own cookies for payments and fraud prevention. See Stripe's cookie policy. |
| Match alerts | Only if you turn alerts on | Your browser installs a small Dupin service worker and a push subscription so alerts can reach you. Turn alerts off, or remove notification permission in your browser, to delete them. |
| Team and league images | When pages show badges and logos | Loaded from our football data provider's image server, which sees your IP address like any website you load images from. We don't use it to track you. |
