Flip Flop Slam (Dép Lào Tuổi Thơ) · updated 19 October 2026

Flip Flop Slam is a browser party game at billthedevstudio.io.vn, made by Bill The Dev Studio (Bill Truong, an independent developer in Ho Chi Minh City, Vietnam). This page explains what the game stores, what it sends and how ads work.

In short

• No accounts, no login, no email or phone number.
• Your player name and look (pet, slipper, card colour) are only used to show you to the other players in your room.
• The game shows Google ads. Google may use cookies to show and measure ads.

Stored on your device

Your browser keeps your player name, look, language, volume, which tutorial steps you have seen, how many matches you have played (used to limit how often ads appear), the days of your first and latest visit (to count how many players come back), and a random device code from the server (to keep your in-game coins and experience on this device). Clear the site's data in your browser to remove them.

Sent to the game server

• While you play: your name, look, slams, chat messages and reactions go to the server, which passes them to the other players in your room. Rooms live only in the server's memory and disappear when the match ends; chat messages are not saved.
• Technical logs: the server logs match events (which seat slammed, who won a round) to fix bugs, without names or chat text. The web server keeps standard access logs (IP address, time, page) to stop attacks; these are rotated and deleted regularly.
• Source counts: when you open the game from a link with ?ref= (for example from TikTok or Facebook), the server only adds one to a daily count for that source. No IP address and no name are stored.
• Bug reports: when you send one with "Report a bug", what you wrote and your device details (game version, browser, screen size, language, room code, the page's last errors) are kept for 90 days and sent to Bill to fix the bug. No name or IP address.
• Player reports: when you report a player, the reason, what you wrote, their name, the room code and their last few chat lines are kept for 90 days and sent to Bill. Not the name or IP address of who reported.
• Progress: the device code, your in-game coins and experience, and a log of what added or spent them (which match, what was bought) are kept on Cloudflare (D1). A device that does not play for 30 days is deleted entirely. No name or IP address.
• Play counts: the server adds up daily numbers such as matches played, match length, time waiting for a match, how many players open the tutorial and how many come back after so many days. Totals only, not tied to you, no IP address or name.

Computer players

When few people are around, "Play now" may match you with computer players so you do not have to wait. Your browser may be asked to run the physics of a computer player's slam, as it does for your own.

Ads

The game shows ads through Google AdSense (H5 Games Ads). Google and its partners may use cookies and identifiers to serve ads, cap how often you see them and measure them, including ads based on your visits to other sites. How Google uses data: policies.google.com/technologies/partner-sites. Turn off personalised ads at adssettings.google.com.

Visitors in the European Economic Area, the UK and Switzerland are asked for consent before any personalised ads.

Ads never appear during a match, and never when you arrive through a room invite link.

Children

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