🛡️ Privacy notice
Braglio is a free daily brain game. You can play without an account, and we collect as little as possible. This page explains everything we store, in plain English.
Playing as a guest (no account)
Your scores, streak, achievements, weekly goals, badges and settings are saved in your browser (local storage). They never leave your device unless you use one of the online features below. You can export, restore or erase this data from Stats.
What we store on our server
| What | When | Why |
|---|---|---|
| A random player ID and device key | The first time you play an official run while online, open a challenge, or set a profile | To put your score on the daily leaderboard and stop duplicate entries |
| Nickname (with a #1234 tag), avatar emoji, country flag | Only if you choose them | Shown on leaderboards. All optional — without a nickname you appear as “Anonymous brain” |
| Daily scores and an answer log (which choice, and when) | For official daily runs played online | To check scores are genuine and to rank them. Practice runs are never uploaded |
| Challenges and “friends” | When you create or play a challenge link | To show head-to-head results and your “friends challenged” board. We never access your contacts |
| Email address | Only if you choose “Save your progress” | To send your one-time sign-in link and, only if you tick the box, reminder emails |
| Saved progress (stats, history, badges) | Only when signed in | To sync your progress across devices |
| Push subscription and time zone | Only if you turn on browser notifications | To send at most one reminder a day at your chosen time, never 9 pm–8 am |
| “Still here” signal (random ID, mid-game or not, country code, phone/computer) | Every 30 s while the game is open and visible | To show how many people are playing right now. Deleted after 24 hours. Not sent with Do Not Track / GPC |
| Anonymous usage events | While the game is open and online | To learn which puzzles are fun and whether people come back. See below |
Anonymous usage counts
Braglio uses its own privacy-friendly counting — no cookies, no advertising, no third-party trackers. Your browser keeps a random ID that is never linked to your nickname, email or player ID. We record simple events such as “page viewed”, “game started”, “game finished”, “result shared” and how many puzzles of each type were answered. Each event also records the country your connection comes from (a two-letter code like “AU”, worked out by our host Cloudflare). We never store your IP address, city or anything more precise. While the game tab is open and visible, your browser also sends a tiny “still here” signal every 30 seconds with the same random ID, whether you are mid-game (daily or practice), your country code and whether you are on a phone or a computer. It lets us see how many people are playing right now; each record is deleted after 24 hours. If your browser sends Do Not Track or Global Privacy Control, no events are sent at all.
Cookies
Braglio sets one cookie, and only if you sign in: a secure session cookie that keeps you signed in. It cannot be read by scripts and is not used for tracking.
Security checks
Some forms may use Cloudflare Turnstile, a privacy-preserving “are you human?” check, to stop spam. The service runs on Cloudflare’s network, which also hosts Braglio.
How long we keep things
- Sign-in links expire after 15 minutes and are deleted within a day.
- Sessions expire after 90 days.
- Scores and profiles stay until you delete them.
- Anonymous events are kept for up to 13 months for year-on-year comparisons.
Delete your data
- Online data: open Settings & reminders on the home screen and choose Delete online data. This permanently removes your nickname, scores, challenges, friends, reminders, saved progress and email.
- On this device: open Stats and choose Erase.
- Reminder emails: every email has a one-click unsubscribe link.
- Notifications: turn them off in Settings or in your browser’s site settings.
