Privacy Policy
Last updated: 17 October 2026
The short version: Little Marble saves your planet on our servers. You can play as a guest, or connect Google to resume on another device. We keep your game progress and, when connected, your Google account identifier and verified email address. No ads, analytics, or third-party trackers. Our host sees your IP address while delivering the service.
Who we are
Little Marble (the game, its website and its apps) is made by Dyxo ("we", "us"). Dyxo is the controller of the personal data described here. Questions and requests: hello@littlemarble.world.
What stays on your device
The game keeps these in your browser's storage or the app's, on your device:
- A cached copy of your planet and pending changes: so you can continue during temporary connection drops. Confirmed progress is stored on our servers.
- Your settings and your progress through the tips: your language, and which first-time notes and coach steps you have seen.
- The play log shown in the settings (☰): what you did and when, for playtests.
- A copy of the game's files, so it opens quickly and works offline.
Gameplay actions are sent to our servers to validate and save progress. Local settings and playtest logs stay on your device unless you choose to share them. Clearing browser data removes local copies and guest access credentials; it does not delete a linked cloud planet.
What we receive
- While you play. Your guest or linked account identifier, planet, and gameplay actions, which we validate and store on Cloudflare. A necessary session cookie keeps you signed in; the server stores a hash of its random value. Sessions expire after 30 days.
- When you connect Google. Google handles sign-in and returns a stable account identifier and verified email address. We request no access to your mail, contacts, or files. Google processes the sign-in under its own privacy policy.
- When you open the game or this website. Our host, Cloudflare, delivers the files. Like any website, it sees your IP address, your browser and device type and the pages you load, and may keep short-lived logs to keep the service secure and working. We don't run analytics, we don't add trackers, and the game's fonts and files all come from our own domain, not from third parties.
- When you write to us. Your email address and what you send us, including a play log if you choose to paste it in, so we can answer you and improve the game.
Why we use it (and on what legal basis)
- Delivering the game and keeping the website safe: the performance of our agreement with you (see the Terms) and our legitimate interest in running a working, secure service.
- Answering your messages and learning from your feedback: our legitimate interest in helping players and making a better game.
We don't sell personal data, we don't show ads, and we don't profile you.
Who we share it with
- Cloudflare, which hosts the game and its website on our behalf.
- Google, when you choose Google sign-in, to authenticate your account.
- Our email provider, which holds the messages you send us.
- Authorities, when the law requires it.
These providers may process data outside your country, including in the United States. Where that happens, the transfer is covered by safeguards recognised by EU law, such as the European Commission's standard contractual clauses or the EU–US Data Privacy Framework.
How long we keep it
- What's on your device: until you clear it or uninstall the game.
- Your cloud account and planets: while you use the service, or until you request deletion. Expired session and temporary sign-in records no longer authorize access.
- Hosting logs: as long as Cloudflare keeps them for security, typically a few days.
- Your messages to us: as long as we need them to help you, and no longer than 2 years.
Your rights
Depending on where you live (and in any case if you're in the European Union or the United Kingdom), you can ask us to access, correct or delete your personal data, to restrict or object to how we use it, and to get a copy of it in a portable format. Local copies and settings can be removed by clearing the game's data. To request access to, export of, or deletion of your server-held account, planets, or messages, write to hello@littlemarble.world; we'll answer within a month. You can also complain to the data protection authority where you live (in France, the CNIL).
Security
Connections to the game and its website are encrypted, and access to our services is limited to the people who make the game. No system is perfectly secure, but we take reasonable steps and will tell you, and the authorities, about a breach when the law requires it.
Children
Little Marble is not meant for children under 13, and we don't knowingly collect data from them. If you are under the age at which you can agree to this on your own in your country, ask a parent or guardian first.
Changes
The game is still being built, and this policy will change with it: for example when friends can play together or if something goes on sale. We'll update this page before those changes reach you, change the date at the top and, for important changes, tell you in the game.
