RNG∞ · last updated October 11, 2026
RNG∞ is a free random number game made for fun. It has no ads, no cookies, no third-party 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, of the month 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.
- The days on which you rolled and how many times each day (kept about 400 days), and the date of your first roll. They are only used to compute totals for the creator of the game, such as how many players were active on a day or came back after their first day.
- 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. The casino leaderboard on the Gamble tab shows, under their player name, the players who won, lost or wagered the most coins in the casino games (coins wagered, net result and number of rounds). Daily and weekly data expire automatically.
Anonymous visit counters
To know roughly how many people visit and where they come from, the site sends one small signal per visit. The server only adds it to daily totals: number of visits, the site you came from (its domain name only, never the full address), a ?ref= tag if the link had one, your country and an approximate area (a square about 100 km wide, as given by the hosting provider: never your address, never your town), the hour of the day, phone or computer, language, and whether it is your first visit or your first visit of the day (two markers kept in your browser). No identifier, no IP address and no cookie is stored, so these totals cannot be linked to you. They are kept about 200 days.
Suggestions, friends and quests
- A suggestion you send with the 💡 button is stored with your player name so the game's creator can read it and reply, and so are the replies you send back in that conversation. Only you, the creator and the people the creator invited to help run the game can see them.
- Your friends list and pending friend requests are stored on the server and visible only to you. A friend can see your lifetime XP, when you last rolled, and the duel you are currently in.
- Daily quest progress, your daily bonus streak, your coins and the skins, buttons and emotes you own are stored on the server.
Duel chat
- Messages written in a duel's chat are shown with your player name to everyone in that duel, spectators included. They are stored with the duel and deleted with it, one day after its last action.
- If you set a password, the server keeps only a scrambled fingerprint of it (scrypt with a random salt), never the password itself. No e-mail address is asked for.
- Messages you send to a friend (💬 on the Friends page) are stored on the server so you two can read them, filtered like the duel chat, and deleted 7 days after the last message of the conversation (at most the last 100 are kept). Only you and that friend can read them in the game; you can block a friend so they can no longer write to you.
- Messages are filtered automatically (insults, links, long numbers), but no filter is perfect: never share personal details such as your full name, address, phone number or social accounts. You can hide any player's messages with the Hide button.
Services used
- Vercel hosts the site and the server functions.
- The database (leaderboard, histories, duels) runs on a virtual server rented from OVHcloud in Europe. Until 28 September 2026 it was hosted by Upstash.
- Google provides Google sign-in (only if you use it) and the web fonts.
Deleting your data
To remove your player and leaderboard entries, open an issue on GitHub with your player name. You can also sign out and clear your browser's data for this site at any time.
