Privacy Policy

Last updated: October 12, 2026

Game Ngày Xưa (gamengayxua.online) is a small site of free browser games. This page explains what data we store, why, and how you can delete it.

1. No account needed

You never need to sign up or log in. We do not ask for your email, phone number or any personal information to play.

2. Data stored on your device

Your browser stores (in localStorage) your game progress: records, gear, Spirit Jade, upgrades, daily quests, sound settings, language, your leaderboard display name and a random player ID. This data stays on your device. Clearing site data in your browser settings removes all of it.

3. Data sent to our server

• Leaderboards: when you submit a score we store the name you typed, your score, the time and your random player ID to show the leaderboard. Don't use your real full name if you don't want others to see it.
• Playing with friends (Sword Immortal Online): your display name and your character's state are relayed through our server to the other players in your room while you play. The server does not keep them after the room closes.

4. Access logs

Like any website, our server keeps access logs with IP address, country, browser, page viewed and time. We only use them to run the site, block attacks and count visits. Logs are deleted automatically after about 14 days. The site runs behind Cloudflare (content delivery and security network), which processes requests to the site and may set technical cookies to stop attacks.

5. Cookies and advertising

The site currently shows no ads and uses no tracking cookies.

If we add advertising in the future (for example Google AdSense), we will update this section before turning it on. Third-party vendors, including Google, may then use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising at adssettings.google.com.

6. Children

Our games are suitable for all ages. We do not knowingly collect personal information from children. Parents who want a name removed from a leaderboard can contact us (section 8).

7. Your rights

You can delete all data on your device at any time (section 2). To remove or change a name submitted to a leaderboard, contact us.

8. Contact

Email [email protected]. We'll reply as soon as we can.

9. Changes

When this policy changes we update this page and the date at the top.
