Privacy policy

Last updated 14 November 2026. This policy covers the game Chan nhau đi at chan.lukepham.uk and the site lukepham.uk (together, “the game”). Operator: Toàn Phạm, contact support@lukepham.uk.

1. Summary

• No account needed. The game never asks for your email, phone number or real name.
• Your progress is stored in your browser and in an anonymous coin wallet on the server.
• The game shows Google AdSense ads. Google and its partners may use cookies to serve and measure ads.

2. Data stored on your device

• Progress and preferences (your browser's localStorage): the captain name you choose, coins, voyages, purchased items, ship model, map, sea size, interface language and a random wallet key.
• Room player ID (sessionStorage): a random ID so reloading the page puts you back in your seat; it disappears when you close the tab.
• Cache (service worker): game files are kept so the game opens faster and uses less data next time.

The game does not set any cookies of its own.

3. Data stored on the server

• Coin wallet: coins, unlocked voyages, shop items, the solo match in progress and how many ads you watched today. The wallet is named after a hash of the random key on your device and is not linked to your name or any personal information.
• 2-player rooms: the captain names of the players, ship models, moves and bet amounts. A room is deleted 30 minutes after both players have left, or after 6 hours without activity. Your opponent and spectators see your captain name.
• Infrastructure: the game runs on Cloudflare. Like any website, Cloudflare processes IP addresses and technical request data to serve pages and block attacks, under Cloudflare's privacy policy. The game uses no analytics or tracking tools of its own.

4. Google AdSense ads and cookies

The game uses Google AdSense to show ads, including rewarded ads that you choose to watch for coins.

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
• You may opt out of personalized advertising in Google Ads Settings, or opt out of other third-party vendors' cookies at aboutads.info.
• Learn more: How Google uses information from sites or apps that use its services.

Users in the European Economic Area, the United Kingdom and Switzerland see Google's consent message before cookies are used for personalized ads, and can change their choice at any time through that message.

When you watch a rewarded ad, the server only records when the ad was started and claimed, to enforce the daily limit; the game receives no information about you from the ad.

5. Children

The game is not directed at children under 13 and does not knowingly collect personal information from children.

6. Deleting your data

• Press Reset progress in the harbor, or clear site data for chan.lukepham.uk in your browser. Once the key on your device is gone, the wallet on the server is no longer linked to you or anyone else.
• To have your server wallet deleted right away, or for any other question, email support@lukepham.uk.
