Your privacy

Redwood Betting Tools Ltd controls the small amount of personal data handled here; the Data Protection Act 2018 and UK GDPR both apply.

Stored on your device

The calculator saves your latest slip (stake, prices, settings and results) in your browser's local storage under the name l15slip, so it's there when you come back. Stored on your device, it isn't a cookie. Clear your browser's site data if you want it gone.

No cookies are set here, no advertising or analytics code runs, and nothing loads from other companies, which is why a cookie banner never appears.

What our servers record

Like any website, our servers log each request: the page, the time, your IP address and the browser's own description of itself. Running the site, keeping it safe and counting page visits is why we keep these logs; that's our legitimate interest. These logs are never used to identify you, sold or passed on, except to Amazon Web Services as host or where the law requires it. Once they stop being needed for those purposes, we delete them.

Your rights

Any personal data we hold about you can be shown to you if you ask. You can ask for correction or deletion, ask us to stop using it, or object to our use of it. Write to us at the address above. An email to contact@lucky15calculator.uk does the same job. Unhappy with our response? You can complain through the Information Commissioner's Office using its complaints page.

Using the calculator

The calculator and guides give you information to help check a slip. Your bookmaker settles your bet by its own rules, and that's the result that matters. Your entries may not match the Rule 4, prices, place terms or bonuses; when a number seems different, look in your account. Nothing here is financial advice.

Bonus figures come from the terms each bookmaker publishes, and the date we read them is shown next to them. Bookmakers can change or withdraw a bonus at any time.

These terms, or the site itself, may be updated by us. Using the site means you accept the terms in force when you use it. Questions about them can be sent to contact@lucky15calculator.uk.

Links to bookmakers

The Gambling Commission licenses every bookmaker linked here, and its public licence register holds the account numbers. Every visitor sees the links, and each one leads to the bookmaker's homepage.

These links carry no tracking at the moment. If we later join a bookmaker's affiliate programme, we may get paid when someone opens an account through a link. How the calculator works stays the same either way.

Staying safer when you gamble

Only adults should be betting; keep any losses within what you can afford. BeGambleAware provides guidance and tools for limits. Where gambling harms you or a person close to you, GamCare keeps the National Gambling Helpline open, free and confidential, day and night.
