About BenchMyBrain
Free brain testing for everyone. No sign-up, no gimmicks, no tracking.
What Is This?
BenchMyBrain is a free brain testing site with 41 interactive cognitive tests — 40 that feed your overall Brain Score, plus a color vision screening. Test your reaction time, memory, focus, spatial reasoning, typing speed, and more.
All tests are original and custom-built for this site. Nothing is embedded from other platforms. Each test runs entirely in your browser with no server-side processing of your performance data (opt-in leaderboard submissions are the one exception).
No Accounts Required
You don't need to create an account or log in. Your personal bests are saved locally in your browser (localStorage) so you can track progress over time.
We don't collect or store any personal information. No email addresses, no passwords, no profiles.
Privacy & Data
Analytics:We use Google Analytics (GA4) to understand site usage — which tests are popular, where visitors come from, device types, etc. This is anonymous and aggregated data only.
No tracking cookies:Beyond Google Analytics, we don't use tracking pixels, third-party cookies, or behavioral tracking.
Payments:Everything is free. If you choose to support the site with an optional donation, it's processed by Stripe — we never see your card details, and it's never required to use anything.
Your test data: All test scores and personal bests stay in your browser. Unless you submit a score to a leaderboard, we never see or store your individual performance.
Leaderboards: If you choose to submit a score, we store your chosen nickname, the score, and a two-letter country code derived from your IP address at submit time (the IP itself is never stored). Nickname, country flag, and score are shown publicly on that leaderboard.
Who Built This?
BenchMyBrain is built and maintained by MeyDev, an independent developer creating free tools, games, and productivity apps.

Every test on BenchMyBrain is free and always will be — no accounts, no test paywalls, no limits on plays. Your scores, personal bests, Brain Score, and the Full Cognitive Report(a detailed breakdown of your results) are all free too. If you find it useful, you can support the site with an optional donation — but nothing here is ever locked.
