Is MyDrawDay affiliated with EuroMillions or any lottery operator?
No. MyDrawDay is not affiliated with, endorsed by, or connected to EuroMillions, SELAE, Camelot, Allwyn, or any national lottery operator, in any country. Every lottery name that appears in the app is used purely to describe that lottery's own publicly published rules and prize format — the same way a currency converter can reference "US Dollar" without being affiliated with the US Treasury.
MyDrawDay is also not a betting service, ticket seller, or lottery operator itself. It doesn't sell tickets, accept wagers, process bets, or handle real winnings in any way — it's an independent informational tool: an odds calculator, a number generator, and a syndicate cost-splitter, built around publicly available math. If you want to actually play, you'd do that through your country's official, licensed lottery operator, entirely separately from anything MyDrawDay does.
