Trampoline Hop · last updated 20th August 2026
Trampoline Hop is a free browser game. It is run by Sam Olliver, trading as a sole trader in the United Kingdom, who is the data controller for everything described here.
If you only play, nothing leaves the device. Your best score, coins, outfits and sound setting are saved in the browser's own storage on that phone or computer. We cannot read it, and clearing your browser data deletes it.
| If a player… | we store | and it is |
|---|---|---|
| puts a score on a scoreboard | the nickname typed in, the score, the chosen outfit, ring colour and the drawn pixel avatar | public, visible to anyone who opens the scoreboard |
| makes an account to save progress | a username, best score, coins, which outfits are owned, and the chosen outfit and ring | private to that account |
| signs in with Google | only the anonymous account identifier Google gives us. No email address is ever stored, and nothing but that identifier is read from what Google sends. | private to that account |
| makes a password instead | a scrambled version of the password, never the password itself. It cannot be turned back into the original, which also means we cannot tell you what it was if it is forgotten. | private to that account |
| adds a friend | the two usernames, and the request until it is accepted or declined | visible to those two players |
| turns on notifications | the subscription the browser issues, which lets us send a message to that device and nothing else | private, and deleted when notifications are turned off |
| sets a good score | the path that run took up the tower, with the nickname and score, so it can be replayed as a "ghost" for other players to race | public as a moving character, and dropped as newer runs replace it |
That is the complete list. There is no analytics, no tracking of what a player does in the game, no profile built about anybody, and nothing sold or shared with anyone for marketing.
The scoreboard is public. The game asks players to pick a nickname rather than use a real name, and says so on the screen where it is typed. If a real name has already been used and you would like it removed, email us and we will take it off.
No ads run in this game at present. None are switched on, so nothing is being shown to anybody today.
If they are switched on, the game may show short video ads that a player can choose to watch in exchange for carrying on after a crash or doubling the coins from a run. They will always be optional. No ad will ever be forced, and no part of the game will be locked behind one.
Because this game is aimed at children, ads will be set up so that they are not personalised: not based on anything a player has done here or anywhere else, and no advertising profile is built. Ads would be served by Google, whose own handling of data is covered by the Google Privacy & Terms. Visitors in the UK and Europe are asked for consent before any advertising cookie is set, and refusing is as easy as agreeing.
| Who | Why |

| Cloudflare | Hosts the game and delivers it to the browser |
| Upstash | Stores the scoreboards, accounts and friend lists |
| Sign-in, ads and the consent message | |
| Google Fonts | Supplies the game's typeface |
Account details stay until the account is deleted. Scoreboard entries stay until they are beaten or removed. Ghost runs are dropped as newer ones replace them. Notification subscriptions are deleted as soon as notifications are turned off.
You can ask to see what we hold, have it corrected, or have it deleted. For a child, a parent or guardian can ask on their behalf. There is no form and no account needed: email us with the nickname or username and we will deal with it, normally within a few days and always within one month.
If you are not happy with how we handle it, you can complain to the Information Commissioner's Office at ico.org.uk.
