Redwood Betting Tools Ltd, of 25 Canada Square, Canary Wharf, London E14 5LQ, United Kingdom, is the operator of Lucky 15 Calculator. Letters posted to that address reach the people behind the site; it's also where any privacy request should go.

Privacy and you

The little personal data this site handles is controlled by Redwood Betting Tools Ltd under the Data Protection Act 2018 and the UK GDPR.

Kept on your device

Your most recent slip (stake, prices, settings and results) is saved by the calculator in your browser's local storage as l15slip, ready for your next visit. Your reply to the age question is stored as l15over18. Both stay on your device, and neither one is a cookie. To remove both, clear your browser's site data.

This site sets no cookies, uses no advertising or analytics code, and nothing loads from other companies, so you won't see a cookie banner.

Recorded by our servers

As on any website, our servers note every request: page, time, your IP address and how the browser describes itself. These logs let us keep the site running, keep it safe and count page visits; that is our legitimate interest. We never use them to identify you, sell them or share them, apart from Amazon Web Services, which hosts the site, or when the law says we must. As soon as they're not needed for those purposes any more, we delete them.

The site checks which country your connection comes from so it can decide which regions may see bookmaker links. The country alone gets used; nothing about it is saved.

The rights you have

You can ask us to show you any personal data we hold on you, to correct or delete it, or to stop using it; you may also object to the way we use it. Use the address above to write to us. Not happy with how we respond? The Information Commissioner's Office has a complaints page you can use.

How to use the calculator

Information to help you check a slip: that is what the calculator and guides provide. The result that matters comes from your bookmaker, which settles your bet by its own rules. What you typed can differ from the Rule 4, prices, place terms and bonuses; if a figure looks different, your account is the place to check. Financial advice is not offered anywhere here.

We take bonus figures from the terms each bookmaker publishes, with the date we read them shown alongside. At any time, bookmakers can change or withdraw a bonus.

We may update the site or these terms. By using the site you accept whichever terms are in force at the time.

Bookmaker links

Each bookmaker we link to is licensed by the Gambling Commission; the account numbers sit on its public licence register. The links lead to each bookmaker's homepage; they appear only for people in Great Britain who have confirmed they are 18 or over.

Right now these links have no tracking on them. Should we later join an affiliate programme run by a bookmaker, we may get paid if someone uses a link to open an account. Either way makes no difference to how the calculator works.

Gambling more safely

Adults are the only people meant to bet; losses should stay affordable. When gambling harms you or someone close to you, GamCare runs the free, confidential National Gambling Helpline day and night; BeGambleAware provides guidance and tools for limits.
