RNG∞ · last updated September 21, 2026
RNG∞ is a free random number game made for fun. It has no ads, no analytics and does not sell or share your data.
Stored in your browser
- Your full roll history, your settings and your player name.
- A random player id and a random secret that let the server recognise your rolls.
If you don't sign in with Google, your settings and secret stay on your device, and your roll history is copied to the server only for your public profile (it is not restored on your other devices). Clearing your browser's site data deletes the local copy.
Stored on the server (leaderboard)
- Your player name, your best roll of the day, of the week and of all time, and how many times you rolled.
- A one-way hash of your secret, used to check that rolls sent under your player id really come from you.
- Your roll history (each number and when you rolled it, up to your last 100,000 rolls): every roll made online, plus, for players from before 23 September 2026, the rolls their device had kept locally (sent once). This powers your public profile and, once you sign in with Google, lets your history, stats and badges follow you on every device.
- If you sign in with Google: your Google account identifier (a number issued by Google), linked to your player id so you get the same player on every device. Your email address is used in your browser to show which account you are signed in with; it is not stored on the server.
To stop abuse, your IP address is used in memory for one minute to count requests; it is never stored. Your player name, best rolls and roll counts are public on the leaderboard. Your public profile (opened by clicking your name) shows your 10 best rolls with their dates, the badges you have collected, your number of rolls, your lifetime XP and when you started playing; it never shows your full roll history. Live duels (player names, duel rolls and reactions) can be watched by anyone who has the duel code; they are deleted one day after the last action. Your unlocked achievements, equipped title and skin, duel record and head-to-head results are public, like your profile. Public duels are listed on the Duel tab while they are running. Daily and weekly data expire automatically.
