Privacy Policy
Last updated: 6 June 2026
This policy explains what personal data GameOn! collects, why, and the rights you have over it. GameOn! is a multi-sport match-reminder app published by MujiLab.
The short version
We collect the minimum needed to run the app: your account, your followed teams, and your reminder settings. There is no advertising SDK and no analytics SDK in the app. We never sell or share your personal data. You can delete your account, and all the data tied to it, at any time from inside the app.
1. Who is responsible for your data
The data controller is MujiLab (sole proprietorship, France), the publisher of GameOn!. For any privacy question or request, contact us at contact@mujilab.com.
2. What we collect, why, and on what legal basis
- Account details (email address, and the name and identifier from your Google account when you sign in with Google). Purpose: create and secure your account and sign you in. Legal basis: performance of our contract with you.
- Device notification token and basic device information (a Firebase Cloud Messaging token). Purpose: deliver the match reminders you ask for. Legal basis: performance of our contract. You can turn notifications off at any time in your device or app settings.
- Your preferences (the teams and athletes you follow, reminder timings, language and theme). Purpose: provide your personalized feed and reminders. Legal basis: performance of our contract.
- Subscription status (whether you are on the free plan or GameOn! Plus, handled through RevenueCat and the app stores). Purpose: manage your subscription and unlock Plus features. Legal basis: performance of our contract.
- Technical and diagnostic data (crash and error logs, and network metadata from our security proxy). Purpose: keep the app stable, secure and working. Legal basis: our legitimate interest in operating a reliable, secure service.
We do not run advertising or analytics SDKs, and we do not build advertising profiles or make automated decisions about you.
3. Who we share it with
We use a small number of trusted service providers (processors) strictly to run the app:
- Google (Firebase Authentication and Firebase Cloud Messaging): sign-in and push notifications.
- RevenueCat: subscription management for GameOn! Plus.
- Sentry: crash and error monitoring (EU region).
- Cloudflare: security proxy and protection against abuse.
- Hetzner (Germany) and Turso: hosting and database.
We do not sell or share your personal data, and we do not disclose it to third parties for their own marketing.
4. Where your data is processed
Our servers and database are hosted in the European Union (Germany), and our error monitoring runs in the EU region. Some of our providers (such as Google, RevenueCat and Cloudflare) may process limited data outside the European Economic Area. Where that happens, the transfer is covered by appropriate safeguards, such as the European Commission's Standard Contractual Clauses or an adequacy decision.
5. How long we keep it
We keep your account data for as long as your account exists. When you delete your account (from inside the app, or by contacting us), your account and the personal data attached to it are deleted. Technical and diagnostic logs are kept only for a limited period and then removed.
6. Your rights
Under the GDPR you have the right to access your data, to have it corrected or erased, to restrict or object to its processing, and to data portability. Where processing is based on consent, you can withdraw it at any time. To exercise these rights, delete your account in the app or email contact@mujilab.com.
You also have the right to lodge a complaint with your local data protection authority. In France, this is the CNIL (cnil.fr).
7. California privacy rights
If you are a California resident, you have the right to know what personal information we collect and why, to request its deletion or correction, and not to be discriminated against for exercising your rights. The categories we collect are described in section 2 (identifiers, contact details, purchase status, and technical data), used only to operate the app.
We do not sell or share your personal information (including for cross-context behavioral advertising), so no "Do Not Sell or Share My Personal Information" action is required.
8. Children
GameOn! is not directed at children under 13, and we do not knowingly collect data from them. If you believe a child has provided us with personal data, contact us and we will delete it.
9. Security
We use industry-standard measures to protect your data, including encrypted connections and access controls. No method of transmission or storage is ever completely secure, but we work to keep your data safe.
10. Changes to this policy
We may update this policy as the app evolves. We will change the "last updated" date above and, for significant changes, let you know in the app.
