Privacy

Greyden Scott develops Greyden Games. This policy covers greyden.games, Hoppy Dungeon, UNG FU, and Star Trail, including their websites, browser games, and iOS and Android apps.

Short version

Effective 6 October 2026

We do not sell personal information for money. Most game progress stays on your device. The websites can use Google Analytics and the Meta pixel to understand visits and to measure and show ads. On hoppydungeon.com, ungfu.app, and startrail.greyden.games those tools stay off in the UK, EU, and EEA until you accept them, and elsewhere they load unless you opt out. greyden.games loads them on each visit. Star Trail's apps use no analytics or advertising. Hoppy Dungeon and UNG FU can report limited app events to Meta, and UNG FU can show an optional rewarded ad.

On your device

Saved games stay on the device or in that browser. We do not receive them from the website. Clearing the site's data, or deleting the app, removes them.

  • Hoppy Dungeon keeps settings, saved equipment, and a pending best score on the iPhone.
  • UNG FU keeps settings, the coin wallet, best score, best distance, tutorial completion, and a pending leaderboard score.
  • Star Trail keeps the journey in progress, a short history of recent runs, sound settings, and the privacy choice, in the browser or in the app.

Hoppy Dungeon's browser alpha may send the level reached when a run ends. That event is anonymous. It does not include a name, email address, Game Center account, or an advertising identifier.

Websites

greyden.games, hoppydungeon.com, ungfu.app, and startrail.greyden.games can load Google Analytics 4 and the Meta pixel. Google Analytics is configured without Google Signals and without ad personalisation. It is used to understand traffic and, on the game sites, how a browser game is played. The pixel measures whether Facebook and Instagram ads bring people to a game, and it can be used to build custom and lookalike audiences so people who have visited may later see ads for that game on Meta's services. Meta can link a visit to a Facebook or Instagram account if you have one.

When a tool is active, Google or Meta may receive an IP address, pages viewed, device and browser type, and referral source. The pixel sends only the events we choose, not every button and form. Waitlist names and email addresses are not sent to Google or Meta, and contact details are not sent to Meta for audience matching.

  • greyden.games records a page view, and a click on a link that leaves the site, including the link address, the destination, and the link text. There is no account and no form that collects a name or email address.
  • hoppydungeon.com can record pages visited, a browser-alpha run started or finished, an App Store page opened, or a waitlist joined.
  • ungfu.app can record pages visited and a browser-game run started or finished.
  • startrail.greyden.games sends a page view only.

Those website tools are never loaded inside the UNG FU or Star Trail apps. Hosting and security providers, including Cloudflare, may process an IP address, browser type, and request time to deliver and protect a site. On the game sites, Cloudflare's country lookup decides whether to ask before loading analytics. That lookup can be wrong if you use a VPN, and it is not stored as a profile.

Consent on the game sites

On hoppydungeon.com, ungfu.app, and startrail.greyden.games, Google Analytics and the Meta pixel are accepted or rejected together. In the UK, EU, and EEA neither loads, and neither sets cookies, until you choose Accept all. Elsewhere they load unless you choose Reject all, or your browser sends a Global Privacy Control signal. That signal keeps both off and hides the banner. Privacy choices in the site footer can change the choice at any time. Rejecting stops further collection from that website. On Star Trail it also clears the analytics and pixel cookies on that site. It does not delete information Google or Meta already hold, and it does not control the apps.

For visitors in the UK, EU, and EEA, analytics and advertising on those game sites rely on consent. Hosting and security rely on our legitimate interest in running a working site. Replies to messages rely on our legitimate interest in helping you.

greyden.games does not show a consent banner and does not respond to Global Privacy Control. Privacy choices on the game sites do not control tracking here. You can block these tools in your browser.

Apps

Star Trail

The iOS and Android apps contain the same game as the website and use no analytics, advertising, or tracking. Apple and Google handle downloads and store accounts under their own policies.

Hoppy Dungeon

The iOS game contains no advertising. Releases with Meta App Events enabled use the Meta Facebook Core SDK to report installs and app opens. When automatic purchase logging is enabled, the SDK also reports purchase events: the product identifier, transaction identifier, purchase time, amount, and currency. Meta may also receive the app and SDK version, device model and operating system, IP address, app or device identifiers, and diagnostics. The game does not use Facebook Login, does not request a Facebook profile, and does not send a Game Center display name or waitlist email to Meta through this integration.

The app asks through Apple's App Tracking Transparency prompt before starting that reporting. If tracking is not allowed, the SDK is not started. The choice can be changed in iOS Settings. The Info screen includes a Tracking Permission button that opens those settings. Apple's advertising identifier stays off even if tracking is allowed. Apple's SKAdNetwork may still provide privacy-preserving attribution reports. The website's privacy choices do not control the iOS SDK, and the app does not currently offer a separate switch for this logging.

UNG FU

After game over in the iOS or Android app, Watch Ad can play a Google AdMob rewarded ad in exchange for 20 coins in the local wallet. Ads do not start on their own. No coins are awarded if the ad is unavailable, fails, or is closed before Google confirms the reward. A completed reward is stored locally so the same callback cannot add coins twice. The app does not send Google a score, character collection, coin balance, purchase, waitlist details, or contact information for this feature.

To request and measure an ad, Google and participating ad buyers may process an IP address, device and operating-system details, app or device identifiers, coarse location inferred from an IP address, advertising identifiers where the platform and your choices permit them, ad views and interactions, and diagnostics. The app uses Google's User Messaging Platform for advertising privacy choices where required. When Google requires an ongoing entry point, Ad privacy choices appears in the options menu.

The apps include the Meta SDK so we can tell which install ads led to an install. When it is enabled, it reports that the app was opened, with the IP address, device model, operating system version, and app version. On Android it also reports the Google advertising ID and the Google Play install referrer. It does not report gameplay, scores, coins, purchases, or waitlist details.

In the UK, EU, and EEA the SDK stays off until you choose Accept all the first time the app opens. Everywhere else it reports the app open unless you choose Reject all. Privacy choices in the options menu can change that later. The app reads the region the device reports, and it asks if that region is unclear. Apple's SKAdNetwork counts installs on the device and gives us only an anonymous campaign total, on every install, with no identifier. The app does not request Apple's advertising identifier. Google's and Meta's SDK disclosures still classify other app-scoped or developer-scoped device identifiers as linked and used for tracking.

For the current iOS app, those disclosures list coarse location, device ID, product interaction, advertising data, crash data, performance data, other diagnostic data, and other data types used for analytics. Coarse location, device ID, product interaction, and advertising data may be linked to you. Device ID is the category declared as used for tracking. Crash, performance, diagnostic, and other analytics data are declared as not linked to you and not used for tracking. Depending on the SDK and the category, they are used for third-party advertising, UNG FU advertising or marketing, analytics, and app functionality such as consent, ad delivery, and diagnostics. They are not used to personalise gameplay or the character shop.

Purchases, leaderboards, and waitlists

Apple processes Hoppy Dungeon payments for class unlocks and the all-classes bundle through StoreKit, including restores and refunds. We do not receive payment-card details. Purchased class unlocks can be restored with the Shop's Restore button. Star Trail has no in-app purchases.

If you use Game Center, Apple authenticates the player account and processes the display name and leaderboard score. Hoppy Dungeon submits the longest completed run. UNG FU submits the best completed-run score, and only a finished run is submitted. On Android, Google Play Games does the same for UNG FU. Apple and Google handle that information underApple's Privacy Policy and theGoogle Privacy Policy.

Waitlists are optional, and the details are kept until you ask for them to be removed or the list is no longer needed.

  • Hoppy Dungeon collects an email address, to confirm the signup and send launch news.
  • UNG FU collects a first name, last name, email address, and an iOS or Android preference, for launch news and possible invitations to help test the game.

How we use it

  • Deliver, secure, and troubleshoot the websites and browser games.
  • Understand website traffic and, where allowed, how a browser game is played.
  • Measure whether ads bring people to a game, an install, or a purchase, and improve those campaigns.
  • Build custom and lookalike audiences so a game's ads can be shown to people who have visited its site.
  • Provide Game Center and Google Play Games leaderboards.
  • Load an optional UNG FU rewarded ad and grant 20 local coins after Google confirms it.
  • Send waitlist confirmation and launch news.
  • Reply when you contact support or send accessibility feedback.

Sharing

We do not sell or rent personal information for money. Information may be processed by service providers only where needed to operate a game: Apple for Game Center and Hoppy Dungeon purchases, Google for Play Games and AdMob, participating ad buyers when you request an UNG FU ad, Meta for the pixel and the app SDKs described above, and infrastructure providers that host a site, store a waitlist, or deliver email. Google's handling of information is described in the Google Privacy Policy. Meta's is described in the Meta Privacy Policy. We may also disclose information if required by law or necessary to protect players and the service.

Under some United States state privacy laws, including the California Consumer Privacy Act, using a pixel for cross-context behavioural advertising counts as sharing or a sale even though no money changes hands. On a game website, Reject all opts you out of that sharing. On greyden.games, blocking the tools in your browser is how you stop that collection.

Your choices

On a game website, choose Accept all or Reject all at the banner, or later with Privacy choices in the footer. Rejecting stops further collection from that website. It does not delete what Google or Meta already hold, which they keep under their own policies, including the retention period set in the Google Analytics property. You can also manage Meta's use of your activity inMeta ad preferences andAccounts Center.

Website privacy choices do not control the apps. Hoppy Dungeon's iOS tracking permission is changed in iOS Settings, and the Info screen can open it. UNG FU's install measurement and ad privacy choices are in the app's options menu. Changing a choice stops or limits later processing as that provider describes it. It does not itself delete information they already hold.

Deletion

To remove Hoppy Dungeon data from an iPhone, open Settings, then General, then iPhone Storage, then Hoppy Dungeon, and choose Delete App rather than Offload App. Deleting an app stops further SDK events from that installation. It does not erase records Apple or Meta already hold, refund a purchase, or remove a purchase entitlement. To remove UNG FU or Star Trail data from a phone, delete the app. To remove a browser save, clear that site's data.

Apple controls App Store purchase history and Game Center records. Google controls Google Play Games records. Manage those through the Apple or Google account.

To ask us to access, correct, or delete information we hold, email the address for that game and say whether the request is about a waitlist, a support message, a website, or app events. Use the email address you originally provided if you can. You do not need a game account or a Facebook account. Do not send passwords or payment-card details. An email address alone may not identify records a Meta SDK already sent, because the games do not use Facebook Login.

If you are in the UK, EU, or EEA, you can also complain to your data protection authority. In the UK, that is the Information Commissioner's Office.

Children

We do not knowingly request personal information from children. If a child has sent an email address, joined a waitlist, or otherwise provided information, contact us and we will remove it where we can.

This policy may be updated as the games change. The effective date above will change when it does. Questions can be sent to the address for the game you use.
