Frequently Asked Questions
Is this service free?
Yes, LottoPro is 100% free to use for everyone. No registration, no subscription, and no hidden fees β ever.
Are the numbers truly random?
Yes. We use the Web Crypto API (crypto.getRandomValues), the same cryptographic standard used in banking software, ensuring every number is genuinely unpredictable.
Does LottoPro generate bonus numbers?
Only for lotteries where the buyer chooses a bonus number: Powerball (Powerball), Mega Millions (Mega Ball), and EuroMillions (Lucky Stars). For UK Lotto, Korea 6/45, and Japan Loto 7, the bonus ball is drawn by the operator β not the player β so we only generate the main numbers.
Can I use the same numbers every week?
Absolutely. Use the "Include Numbers" field in the generator to lock in specific numbers you always want included. Your history is also saved automatically so you can reference past sets.
Does using a number generator improve my chances of winning?
No. Each lottery draw is completely independent. No tool, system, or strategy can improve your probability of winning. LottoPro is provided for entertainment and convenience only.
Is my data stored or shared?
We do not collect personal data. Your generated number history is stored only in your own browser (localStorage) and is never transmitted to our servers. See our Privacy Policy for full details.
