Many players ask: "Who can see my score?" On Fast Reaction Test, your benchmark history and tool settings usually stay in your browser on that phone or computer. We do not ask for your name, email, or password to play. You can test without an account.

What local storage means

Browsers can save small files for a site. That is how your last median ms can appear next visit. It is like a sticky note on your own desk, not a public billboard. Other people cannot read that note from their house.

What we do not do by default

  • We do not upload your round times to our servers for the core test
  • We do not sell your reaction history
  • We do not need your real name to click green

If you tap Share, you choose what text leaves your device through your own apps. That is your decision.

When internet tools appear

We may show ads later to keep the site free. Ad companies may use cookies under their own rules. Read our Privacy Policy for details. Ads do not change how the timer works. Timing still uses your device clock.

Clearing your data

Open browser settings. Find "site data" or "cookies and site data." Remove data for this website. Your scores reset. Useful on shared school computers. Always log out of shared PCs after play.

Kids and parents

Parents can test with children and talk about privacy. No kid should share personal info in chat while sharing a score. Share only the ms number and a fun message, not your address or school name.

School Chromebooks

Some schools wipe browsers daily. Scores may vanish overnight. That is normal. Export CSV if your teacher allows saving work.

Questions

Email us through the Contact page for privacy questions. We aim to reply within a few business days. This guide is for trust, not legal advice. See the full Privacy Policy for official wording.

Shared family computers

Brothers and sisters on one PC share one browser history. Anyone using that browser may see past scores. Clear site data before guests use the PC if you want a fresh start.

Phones and tablets

Your phone history stays on that phone unless you clear it or use cloud browser sync. Sync can copy history to a tablet. Check sync settings if you care who sees scores.

What ads may see later

If we show ads, ad partners may read cookies about visits. That is different from uploading your round times. Read the Privacy Policy before ads go live. Parents can use browser controls to limit ad tracking.

GDPR and your rights

Some countries let you ask what data a site holds. Our core play stores scores locally. Contact us through the Contact page for privacy questions. We answer in plain words when we can.

Teaching digital literacy

Use this site to explain local storage vs accounts. Kids learn that free games can still respect privacy when designed well. Always ask an adult before sharing anything online.

Backup your own log

Screenshots or CSV export are your backup. Do not rely on a school Chromebook to keep data forever. Save what matters to you.

Incognito mode

Private browsing may forget scores when you close the window. That helps on a friend's device. It also means you lose history on purpose. Pick normal mode if you want a chart over weeks.

Updates and clearing cache

Browser updates rarely wipe data alone. Clearing all cache does. Read the checkboxes before you clear. Keep cookies for this site if you want scores to stay.

Comparing to big sites that need accounts

Some sites force login and store clouds of data. We chose local storage for simple play. That trade means you own the backup job. Screenshots and CSV are your friends.

Trust and AdSense

When ads appear, they fund free tools. Ads do not need your reaction times to show. We still want you to know what is local vs what is ad tech. Ask questions on the Contact page any time.

Quick recap

Scores live on your device in browser storage. No account is required to play. Sharing is your choice. Clear site data to reset. Shared PCs need extra care. Read the Privacy Policy for ads and cookies. Export or screenshot if you want backups.

One last tip

Talk with a parent before you post any score online. Safe sharing is part of being a good digital citizen. Keep your real name and school out of public posts. A number alone is enough for friendly bragging.

Play with peace of mind

Test, improve, share if you want, or stay quiet. Your reflex journey can stay yours.
