MarbleRoo Privacy Policy
Last updated: November 11, 2026
This policy explains what the MarbleRoo game collects, why, and the choices you have. MarbleRoo ("we", "us") is made in California, United States. Questions or requests: hello@marbleroo.com. The game's rules and weekly prizes are in our Terms and Prize Rules.
What we collect
| Data | Why |
|---|---|
| A player ID. The game creates a hidden account with a random ID on your device. | To keep your place on the boards and let only you change your own scores. |
| Your Google or Apple account details, only if you sign in. Firebase stores your email address and basic profile information. With Apple, you can choose to hide your email; Apple then gives us a private relay address instead. | To bring your account back on a new phone and let you win weekly prizes. |
| Your saved progress. A backup of your game progress: stars, levels, cosmetics, prizes and game settings, with a short summary (level and star counts) and notes from automatic checks for impossible jumps in stars or levels. | To bring your progress back on a new phone, and to keep the boards fair: a player whose progress jumps further than a person could is kept off the boards. Only you and we can read it. |
| Leaderboard details. The name you choose for the boards (or a game-generated one like "Swift Otter 42"), with a short number tag, when you last changed it, your furthest level, weekly scores, whether you are signed in, and when each was sent. Prize claims are linked to your player ID. | To run the public boards and weekly prizes. Your name, tag and scores are visible to other players and to anyone who reads the boards. Names are checked for rude words, and we may change a name that breaks the rules. |
| A player summary. Your board name, furthest level, star count, when you last played, and whether the automatic checks marked your progress. | So the MarbleRoo team can find your account when you ask for help, send you messages or gifts, and keep the boards fair. Only we can read it. |
| Messages from the team. Messages and gifts we send to you in the game's mailbox, and any star or level corrections we make to your progress. | To tell you about your account (for example, if it is being reviewed) and to send gifts. Only you and we can read them. |
| Crash reports. Device model, operating system, app version, a device installation ID, and what the app was doing when it crashed. | To find and fix problems. |
| Play statistics. A random app ID, your device type and operating system, your rough location such as your country, how often and how long you play, and game events such as levels won, Rush runs finished and arcade prizes won. | To see whether players come back and improve the game. This doesn't use your advertising ID, your name or your email. |
| App and device checks. Google and Apple services confirm that requests come from the real app on a genuine device. | To protect the game and its boards from abuse. |
| The website's waitlist, only if you join it. Your email address, whether you use an iPhone or Android, your rough country from your browser's language setting, and when you joined. | To invite you to test MarbleRoo and to email you when it launches, with the right store link. Only we can read it. Unsubscribe from any email, or email us to be removed. |
| Suggestion box messages, only if you send one. Your message, any contact details you choose to add, and any photos you attach. | To read and reply to your message. |
Google's servers also process technical information, such as your IP address, when your device connects to these services.
What stays on your device
Your stars, levels, cosmetics and settings are saved on your device, and a backup is kept with your account (see "Your saved progress" above). Sound and music settings stay on your device only. The game uses motion sensors to detect a shake, and this stays on your device. It only reaches your camera or photos if you choose to attach a picture to a message.
Who handles your data
We don't sell your data, and we don't share it for targeted advertising ("cross-context behavioral advertising"). We use Google services to run the game: Firebase Authentication, Realtime Database, App Check, Crashlytics and Google Analytics for Firebase, and Google Sheets and Drive for suggestion box messages. If you sign in with Apple, Apple handles that sign-in under its own privacy policy. Apple or Google may also process data when they check the app. Google's servers may be outside your country, including in the United States. See Google's Privacy Policy.
We may share information if the law requires it, or to protect the game and its players.
Why we're allowed to use it
Where laws like the GDPR or UK GDPR apply, we use your information because:
- It's needed to provide the game you asked for: your account, saved progress, board name and scores, prizes, and messages from the team.
- We have a legitimate interest in keeping the game fair, safe and working: the cheat checks, crash reports, play statistics and app checks.
- You agreed to it: signing in with Google or Apple, sending a suggestion box message, or joining the website's waitlist. You can withdraw your agreement at any time.
How long we keep it
- Account, saved progress and board rows: until you delete your account. Past weekly boards are otherwise kept.
- Prize claims: these hold only your player ID and which prize was claimed. They stay after deletion so a prize can't be claimed twice.
- Crash reports: 90 days (Google's Crashlytics keeps them that long).
- Play statistics: for the period set in Google Analytics, 14 months at most.
- Suggestion box messages: for as long as they're useful, or until you ask us to delete them.
Deleting your data and your rights
You can delete your account in the game under Settings > Account > Delete account, or follow these steps if you no longer have the game. Depending on where you live, you may also have the right to see, correct, delete or move your data, or to object to how we use it. Email us to make a request.
Children
MarbleRoo is meant for people aged 13 and over. It is not directed at children under 13, and we don't knowingly collect their personal information. If you believe a child under 13 has given us information, email us and we will delete it.
Security
We use database rules and app checks to protect your information, but no online service can be completely secure.
Changes
If we change this policy, we'll update this page and the date above, and tell you in the game if the change is important.
